5:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
28:12Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
49:67ErrorThe "summary" attribute has an invalid attribute value "". Try using one of the following values: an alphanumeric string or a string.

<table border="0" cellspacing="0" cellpadding="0" summary="" class="TabellaCentrale">
 

49:10Message (Good Style)Consider using the "width" attribute with the "table" element. This is considered to be good style and can cause the table and page to render faster. Note that this is not a deprecated attribute in HTML 4.01 nor XHTML 1.0. It's also a valid XHTML 1.1 attribute.
49:10Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.
132:4Error (HTML 4.0 Compatibility)[81] The "align" attribute may not be used with the "P" element in a strict HTML 4.0/4.01 document. Instead of align="justify", consider using the CSS "text-align: justify" instead.

<P align=justify><IMG height=60 alt="" src="http://www.apat.gov.it/certificazioni/site/_images/LogoEmasCER.gif" width=41> <IMG height=60 alt="" src="http://www.apat.gov.it/certificazioni/site/_images/LogoEcolabelCER.gif" width=41> Il Quinto Programma d’azione in campo ambientale dell'Unione Europea (1993-2000), si è basato su principi innovativi capaci di incidere non solo sull'impostazione della nuova legislazione ambientale, ma anche sui processi produttivi&nbsp;delle imprese e sulle modalità di comunicazione con il pubblico. Queste ultime si sono concretizzate nei due schemi di certificazione ambientale EMAS ed Ecolabel che si prefiggono l’obiettivo di promuovere lo sviluppo economico in armonia con l’ambiente. <BR>In linea con <STRONG>l’evoluzione delle politiche ambientali</STRONG> (produzione rispettosa dell’ambiente e consumo consapevole come elementi sinergici verso la creazione del “mercato verde”), i due Regolamenti EMAS ed Ecolabel sono stati profondamente innovati nel 2000-2001.</P>
 

132:254WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 132. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. If you are wanting the euro sign, then it is recommended that the character reference "&#8364;" be used. Another option would be to use the entity reference "&euro;".
132:4Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="justify", consider using the CSS "text-align: justify" instead.
133:2MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
134:2MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
141:42Message[41] The "span" tag has no attributes. Attributes are normally used with the "span" element to provide functionality.
145:2Message[41] The "div" tag has no attributes. Attributes are normally used with the "div" element to provide functionality.
145:7Message[41] The "span" tag has no attributes. Attributes are normally used with the "span" element to provide functionality.
147:2MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
147:29Message[41] The "div" tag has no attributes. Attributes are normally used with the "div" element to provide functionality.
147:34Message[41] The "span" tag has no attributes. Attributes are normally used with the "span" element to provide functionality.
148:2WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 148. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. Consider using "&#710;" instead of this character.
149:2MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.

162:6MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
163:93WarningThe "h3" header element contains no text. Header elements are important and should contain appropriate header text.
164:2Message (Good Style)[7] The "height" and "width" attributes should be used with the "img" element. Using these attributes generally result in faster and smoother (less jumpy) rendering. Using them is also considered to be good style.
194:868WarningUsing space characters in URLs may cause problems. If spaces must be used in URLs, then they should be encoded as "%20" (without the quotes). However, avoid spaces in URLs whenever possible and consider using the underscore character (_) instead of space characters in directory names and filenames.
194:868Warning[33] The "href" attribute has a value that has leading or trailing space characters. These spaces should probably be removed.
194:382Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="http://www.europa.eu.int/comm/environment/emas/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
213:3MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
214:14Warning[75] The "href" attribute specifies an internal link that may not be wanted. An internal link name should usually follow the # character, but it doesn't in this case. However, if the top of the current document is being referenced, then this message should be ignored because an internal link name is not needed.
 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou have one or more internal links linking to an ID link destination. Browser support for this is currently very poor. Consider using something like <a name="MenuSinistro"> ... </a> or <a name="MenuSinistro" id="MenuSinistro"> ... </a> instead.
 CommentYou may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options.
 CommentPossibly misspelled words (262, 176 unique): agevolazioni (1x), agire (1x), albergo (1x), alla (1x), anche (1x), Angolo (1x), armonia (1x), Attivit (1x), azione (1x), basato (1x), behavior.css (1x), Benvenuto (1x), Bienno (1x), capaci (1x), Catalogo (1x), certificazione (1x), CERTIQUALITY (1x), che (1x), chiusura (1x), Codici (1x), Comitato (1x), Commissione (1x), comunicazione (1x), concretizzate (1x), consapevole (1x), consumatore (1x), consumatori (1x), consumo (1x), Contatti (1x), Contenuti (1x), Contributo (1x), Convegno (1x), corpo (1x), CorpoPagina (1x), creazione (1x), criteri (1x), dei (1x), dell'Unione (1x), dell (1x), DG (1x), diffusione (1x), disponibile (1x), d (1x), d (1x), Ecoaudit (1x), economico (1x), elementi (1x), endif (1x), Europa (1x), Europea (1x). List limited to first 50 unique words.
 CommentHTML 4.01 Strict document detected.
 Comment (Search Engine)[113] Random Search Engine Tip #12 - Many elements support the "title" attribute that is used for annotation (do not confuse the "title" element with the "title" attribute). Consider annotating tags like "a" with something like title="Read about <keywords>". Annotate with keywords and search terms. Some browsers, like Firefox, will also display the value of the "title" attribute when the user hovers the mouse over content with a "title" attribute.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)"> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)"> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.
 Comment[10] CSE HTML Validator Std/Pro allows you to disable certain messages (like this example message) and groups of related messages by disabling flags. For instance, the [10] at the beginning of this message indicates that you can disable this message by disabling validator flag 10.

85:31Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "IMG" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
85:108Error (HTML 4.0 Compatibility)[81] The following attributes may not be used with the "IMG" element in a strict HTML 4.0/4.01 document: "align" and "border". Instead of the "BORDER" attribute, consider using the "border" CSS property. Example: style="border: 1px solid".

<p><IMG SRC="img/italia_stampati2.gif" WIDTH="643" HEIGHT="630" USEMAP="#MapMap" BORDER="0"></P><HR><MAP NAME="MapMap">
 

85:31Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.
86:2Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "AREA" element. This attribute lets authors specify alternate text to serve as content when the element cannot be rendered or accessed normally. For example, this attribute is critical for visually impaired users and user agents that cannot display images and image maps.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou can ignore the nesting errors by turning off the option to check HTML tag nesting. However, it is recommended that you leave this feature enabled. This option is in CSE HTML Validator's Validator Engine Options.
 CommentYou have one or more internal links linking to an ID link destination. Browser support for this is currently very poor. Consider using something like <a name="MenuSinistro"> ... </a> or <a name="MenuSinistro" id="MenuSinistro"> ... </a> instead.

 Comment (Search Engine)[113] Random Search Engine Tip #12 - Many elements support the "title" attribute that is used for annotation (do not confuse the "title" element with the "title" attribute). Consider annotating tags like "a" with something like title="Read about <keywords>". Annotate with keywords and search terms. Some browsers, like Firefox, will also display the value of the "title" attribute when the user hovers the mouse over content with a "title" attribute.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)"> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.

4:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
14:2Message (Microsoft Internet Explorer) [CSS][600] The "behavior" CSS property is not an official CSS property and is only supported by Internet Explorer 5.0+. Firefox, Netscape, Opera, and most other browsers do not support this property.
23:40Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
46:67ErrorThe "summary" attribute has an invalid attribute value "". Try using one of the following values: an alphanumeric string or a string.

<table border="0" cellspacing="0" cellpadding="0" summary="" class="TabellaCentrale">
 

46:10Message (Good Style)Consider using the "width" attribute with the "table" element. This is considered to be good style and can cause the table and page to render faster. Note that this is not a deprecated attribute in HTML 4.01 nor XHTML 1.0. It's also a valid XHTML 1.1 attribute.
46:10Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.

694:20Message (Good Style)[7] A heading has been used without previously using the higher heading levels. Some HTML authors consider this bad style. For example, if "h4" is used, then "h1", "h2", and "h3" should have already been used, in that order.
695:23Error (HTML 4.0 Compatibility)[81] The "align" attribute may not be used with the "h5" element in a strict HTML 4.0/4.01 document. Instead of align="center", consider using the CSS "text-align: center" instead.

695:39Error (HTML 4.0 Compatibility)[76] The "font" element should not be used in a strict HTML 4.0/4.01 document. Style sheets should be used instead of this element. Note that you may want to consider using a different DOCTYPE declaration that is more lenient and allows more element, such as an HTML 4.01 transitional DOCTYPE. For example, you may want to use the HTML 4.01 transitional DOCTYPE: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.

697:78Warning[64] An invalid character reference was found in the "href" attribute value. The most likely cause is an unencoded ampersand. This is a common error that should be fixed (even though it still works most of the time). Ampersands should be encoded as "&amp;" even when specifying script variables. Web browsers will convert the "&amp;" entities back to just '&'. Example: href="script.cgi?var1=value&var2=value" should be href="script.cgi?var1=value&amp;var2=value". Note that the ampersand in the URL was encoded as "&amp;". Other causes of invalid references are misspelled entity names and missing semicolons.
697:177Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
697:177Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.

701:35Message (Good Style)The "strong" element should be used instead of the "b" element when you want to denote strong emphasis.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentComments should be in the '<!-- (comment here) -->' format. However, most browsers will accept '<! ... >' as a comment. If you do not want to use only '<!-- ... -->' comments, then you should turn off strict comments. This option is in CSE HTML Validator's Validator Engine Options.
 CommentYou can disable all the error messages for improperly quoted attribute values by having HTML Validator ignore and disregard the quotation mark requirements for attribute values. This option is in CSE HTML Validator's Validator Engine Options. However, it is recommended that you leave these error messages enabled and that you properly enclose attribute values in quotation marks.
 CommentYou can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
 CommentPossibly misspelled words (69, 34 unique): Acciaierie (1x), APPLICATIVI (1x), asfalto (1x), Atti (1x), Biomedicale (1x), Calcestruzzo (1x), Cartario (1x), CASI (1x), elettriche (1x), Falegnamerie (1x), Firenze (1x), Fonderie (1x), fondino (1x), Galvanico (1x), ghisa (1x), Guida (1x), immagini (1x), oliva (1x), Presentazione (1x), Rubinetterie (1x), segherie (1x), Seminario (1x), Tessile (1x), valvolame (1x), ambientale (2x), cicli (2x), dei (2x), di (2x), l'analisi (2x), produttivi (2x), Metodologie (3x), Apri (10x), finestra (10x), nuova (10x).

 Comment (Search Engine)[113] Random Search Engine Tip #12 - Many elements support the "title" attribute that is used for annotation (do not confuse the "title" element with the "title" attribute). Consider annotating tags like "a" with something like title="Read about <keywords>". Annotate with keywords and search terms. Some browsers, like Firefox, will also display the value of the "title" attribute when the user hovers the mouse over content with a "title" attribute.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)"> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)"> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.

21:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
35:16Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
74:35Message (Tips)[6] Email spam is a huge problem nowadays. Be aware that mailto email addresses are easily harvested for spam lists by automated programs. Consider alternate, but less user-friendly, ways of distributing email addresses if spam is a concern.

81:4Message (Good Style)Consider using the "width" attribute with the "table" element. This is considered to be good style and can cause the table and page to render faster. Note that this is not a deprecated attribute in HTML 4.01 nor XHTML 1.0. It's also a valid XHTML 1.1 attribute.
81:4Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.

5:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
28:12Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
49:67ErrorThe "summary" attribute has an invalid attribute value "". Try using one of the following values: an alphanumeric string or a string.

<table border="0" cellspacing="0" cellpadding="0" summary="" class="TabellaCentrale">
 

49:10Message (Good Style)Consider using the "width" attribute with the "table" element. This is considered to be good style and can cause the table and page to render faster. Note that this is not a deprecated attribute in HTML 4.01 nor XHTML 1.0. It's also a valid XHTML 1.1 attribute.
49:10Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.
132:4Error (HTML 4.0 Compatibility)[81] The "align" attribute may not be used with the "P" element in a strict HTML 4.0/4.01 document. Instead of align="justify", consider using the CSS "text-align: justify" instead.

<P align=justify><IMG height=60 alt="" src="http://www.apat.gov.it/certificazioni/site/_images/LogoEmasCER.gif" width=41> <IMG height=60 alt="" src="http://www.apat.gov.it/certificazioni/site/_images/LogoEcolabelCER.gif" width=41> Il Quinto Programma d’azione in campo ambientale dell'Unione Europea (1993-2000), si è basato su principi innovativi capaci di incidere non solo sull'impostazione della nuova legislazione ambientale, ma anche sui processi produttivi&nbsp;delle imprese e sulle modalità di comunicazione con il pubblico. Queste ultime si sono concretizzate nei due schemi di certificazione ambientale EMAS ed Ecolabel che si prefiggono l’obiettivo di promuovere lo sviluppo economico in armonia con l’ambiente. <BR>In linea con <STRONG>l’evoluzione delle politiche ambientali</STRONG> (produzione rispettosa dell’ambiente e consumo consapevole come elementi sinergici verso la creazione del “mercato verde”), i due Regolamenti EMAS ed Ecolabel sono stati profondamente innovati nel 2000-2001.</P>
 

132:254WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 132. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. If you are wanting the euro sign, then it is recommended that the character reference "&#8364;" be used. Another option would be to use the entity reference "&euro;".
132:4Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="justify", consider using the CSS "text-align: justify" instead.
133:2MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
134:2MessageThe "p" element is empty. Consider removing this element if it is not needed.

163:93WarningThe "h3" header element contains no text. Header elements are important and should contain appropriate header text.
164:2Message (Good Style)[7] The "height" and "width" attributes should be used with the "img" element. Using these attributes generally result in faster and smoother (less jumpy) rendering. Using them is also considered to be good style.
194:868WarningUsing space characters in URLs may cause problems. If spaces must be used in URLs, then they should be encoded as "%20" (without the quotes). However, avoid spaces in URLs whenever possible and consider using the underscore character (_) instead of space characters in directory names and filenames.
194:868Warning[33] The "href" attribute has a value that has leading or trailing space characters. These spaces should probably be removed.
194:382Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="http://www.europa.eu.int/comm/environment/emas/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
213:3MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
214:14Warning[75] The "href" attribute specifies an internal link that may not be wanted. An internal link name should usually follow the # character, but it doesn't in this case. However, if the top of the current document is being referenced, then this message should be ignored because an internal link name is not needed.
 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou have one or more internal links linking to an ID link destination. Browser support for this is currently very poor. Consider using something like <a name="MenuSinistro"> ... </a> or <a name="MenuSinistro" id="MenuSinistro"> ... </a> instead.
 CommentYou may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options.

 Comment (Search Engine)[113] Random Search Engine Tip #12 - Many elements support the "title" attribute that is used for annotation (do not confuse the "title" element with the "title" attribute). Consider annotating tags like "a" with something like title="Read about <keywords>". Annotate with keywords and search terms. Some browsers, like Firefox, will also display the value of the "title" attribute when the user hovers the mouse over content with a "title" attribute.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)"> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)"> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.
 Comment[10] CSE HTML Validator Std/Pro allows you to disable certain messages (like this example message) and groups of related messages by disabling flags. For instance, the [10] at the beginning of this message indicates that you can disable this message by disabling validator flag 10. If you are using HTML Validator's integrated editor, then you can simply use your mouse on this message to open the context menu (usually done by right-clicking the mouse on this message) and select 'Disable Flag 10' to disable this message. For more information about disabling messages, please look at the Configuration section in the documentation.
 CommentCSE HTML Validator Std/Pro allows you to disable many messages on an individual basis without using flags. For instance, you can disable this message by using HTML Validator's integrated editor to open the context menu for this message (usually done by right-clicking the mouse on this message) and selecting 'Options for this Message->Disable Message' to disable this message. For more information about disabling messages, please look at the Configuration section in the documentation.

120:264WarningUsing space characters in URLs may cause problems. If spaces must be used in URLs, then they should be encoded as "%20" (without the quotes). However, avoid spaces in URLs whenever possible and consider using the underscore character (_) instead of space characters in directory names and filenames.
120:264Warning[33] The "href" attribute has a value that has leading or trailing space characters. These spaces should probably be removed.
120:93Message (Good Style)[7] A heading has been used without previously using the higher heading levels. Some HTML authors consider this bad style. For example, if "h4" is used, then "h1", "h2", and "h3" should have already been used, in that order.
131:3MessageThe "p" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
132:14Warning[75] The "href" attribute specifies an internal link that may not be wanted. An internal link name should usually follow the # character, but it doesn't in this case. However, if the top of the current document is being referenced, then this message should be ignored because an internal link name is not needed.
 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou have one or more internal links linking to an ID link destination. Browser support for this is currently very poor. Consider using something like <a name="MenuSinistro"> ... </a> or <a name="MenuSinistro" id="MenuSinistro"> ... </a> instead.
 CommentYou may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options.

 Comment (Search Engine)[113] Random Search Engine Tip #12 - Many elements support the "title" attribute that is used for annotation (do not confuse the "title" element with the "title" attribute). Consider annotating tags like "a" with something like title="Read about <keywords>". Annotate with keywords and search terms. Some browsers, like Firefox, will also display the value of the "title" attribute when the user hovers the mouse over content with a "title" attribute.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)"> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)"> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.

5:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
28:12Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
49:67ErrorThe "summary" attribute has an invalid attribute value "". Try using one of the following values: an alphanumeric string or a string.

<table border="0" cellspacing="0" cellpadding="0" summary="" class="TabellaCentrale">
 

49:10Message (Good Style)Consider using the "width" attribute with the "table" element. This is considered to be good style and can cause the table and page to render faster. Note that this is not a deprecated attribute in HTML 4.01 nor XHTML 1.0. It's also a valid XHTML 1.1 attribute.
49:10Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.
99:2MessageThe "p" element is empty. Consider removing this element if it is not needed.
