HTML for CGM Acronym

when CGM means Computer Graphics Metafile

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 CGM stands for Computer Graphics Metafile 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/Computer-Graphics-Metafile/" title="Computer Graphics Metafile"
onclick="if (confirm('CGM stands for Computer Graphics Metafile')) return false;"
>
<abbr>CGM</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 Computer Graphics Metafile, the meaning of the acronym CGM, 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/Computer-Graphics-Metafile/" title="Computer Graphics Metafile"
onclick="if (confirm('CGM stands for Computer Graphics Metafile')) return false;"
>
<dfn><abbr title="Computer Graphics Metafile">CGM</abbr>
</a> is ...(definition of Computer Graphics Metafile)....</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 CGM acronym shows the expanded meaning of the acronym):

A CGM is ...(definition of "Computer Graphics Metafile")....

If you are creating HTML code that simply expands the acronym then indicate that it is the CGM 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/Computer-Graphics-Metafile/" title="Computer Graphics Metafile"
onclick="if (confirm('CGM stands for Computer Graphics Metafile')) return false;"
>
<dfn title="CGM"><abbr title="Computer Graphics Metafile">CGM</abbr></dfn>
</a> it is the abbreviation for Computer Graphics Metafile.</p>

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

When we use the acronym CGM it is the abbreviation for Computer Graphics Metafile.

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.
