HTML for CD-ROM Acronym

when CD-ROM means Compact Disc Read-Only Memory

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 CD-ROM stands for Compact Disc Read-Only Memory 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/Compact-Disc-Read-Only-Memory/" title="Compact Disc Read-Only Memory"
onclick="if (confirm('CD-ROM stands for Compact Disc Read-Only Memory')) return false;"
>
<abbr>CD-ROM</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 Compact Disc Read-Only Memory, the meaning of the acronym CD-ROM, 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/Compact-Disc-Read-Only-Memory/" title="Compact Disc Read-Only Memory"
onclick="if (confirm('CD-ROM stands for Compact Disc Read-Only Memory')) return false;"
>
<dfn><abbr title="Compact Disc Read-Only Memory">CD-ROM</abbr>
</a> is ...(definition of Compact Disc Read-Only Memory)....</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 CD-ROM acronym shows the expanded meaning of the acronym):

A CD-ROM is ...(definition of "Compact Disc Read-Only Memory")....

If you are creating HTML code that simply expands the acronym then indicate that it is the CD-ROM 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/Compact-Disc-Read-Only-Memory/" title="Compact Disc Read-Only Memory"
onclick="if (confirm('CD-ROM stands for Compact Disc Read-Only Memory')) return false;"
>
<dfn title="CD-ROM"><abbr title="Compact Disc Read-Only Memory">CD-ROM</abbr></dfn>
</a> it is the abbreviation for Compact Disc Read-Only Memory.</p>

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

When we use the acronym CD-ROM it is the abbreviation for Compact Disc Read-Only Memory.

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.
