HTML for CDATA Acronym

when CDATA means Character Data

New! Now updated with the inheritance rules for the title attribute in HTML 5

The easiest way to create HTML code indicating that the acronym CDATA stands for Character Data is to simply include the acronym in an HTML <a> tag and an abbreviation tag (not an acronym tag):

<a href="http://www.Acronyms.net/terms/c/Character-Data/" title="Character Data"
onclick="if (confirm('CDATA stands for Character Data')) return false;"
>
<abbr>CDATA</abbr>
</a>

This is the recommended code for both HTML 4 browsers and HTML 5 browsers. Some browsers, most notably IE, do not activate help when the title attribute is coded on the <abbr> tag, but they do work as expected for titles on the <a> tag. The <abbr> tag inherits its title attribute from the parent <a> tag.

If you are creating HTML code for the definition of Character Data, the meaning of the acronym CDATA, then include a <dfn> definition tag around the <abbr> abbreviation tag and follow the entire HTML code for the hypertext link with the definition of the term:

<p>A <a href="http://www.Acronyms.net/terms/c/Character-Data/" title="Character Data"
onclick="if (confirm('CDATA stands for Character Data')) return false;"
>
<dfn><abbr title="Character Data">CDATA</abbr>
</a> is ...(definition of Character Data)....</p>

The <dfn> tag gets the term being defined from the title attribute of the <abbr> tag. The result should look like this (hovering your mouse over the CDATA acronym shows the expanded meaning of the acronym):

A CDATA is ...(definition of "Character Data")....

If you are creating HTML code that simply expands the acronym then indicate that it is the CDATA acronymn which is being defined using an HTML <dfn> tag with a title attribute around the <abbr> tag and follow the HTML for the hypertext link with the acronym definition:

<p>When we use the acronym <a href="http://www.Acronyms.net/terms/c/Character-Data/" title="Character Data"
onclick="if (confirm('CDATA stands for Character Data')) return false;"
>
<dfn title="CDATA"><abbr title="Character Data">CDATA</abbr></dfn>
</a> it is the abbreviation for Character Data.</p>

The result should look like this (hovering your mouse over the CDATA acronym shows the definition):

When we use the acronym CDATA it is the abbreviation for Character Data.

Acronym Vocabulary URI Declaration

For the remaining examples, the Acronym Vocabulary namespace URI needs to be declared for use with element tag names and attribute values. For an HTML web page, the beginning of the file should look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html [
<!ENTITY at "http://Acronyms.net/terms/">
<!ENTITY av "http://Acronyms.net/vocabulary/">
]>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:av="&av;">
<head>
<style type="text/css">
.hide { display: none }
</style>
...

This only needs to be done once per document file.
