Three Letter Acronym

HTML for TLA Acronym

when TLA means Three Letter Acronym

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 TLA stands for Three Letter Acronym 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/t/Three-Letter-Acronym/" title="Three Letter Acronym"
onclick="if (confirm('TLA stands for Three Letter Acronym')) return false;"
>
<abbr>TLA</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 Three Letter Acronym, the meaning of the acronym TLA, 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/t/Three-Letter-Acronym/" title="Three Letter Acronym"
onclick="if (confirm('TLA stands for Three Letter Acronym')) return false;"
>
<dfn><abbr title="Three Letter Acronym">TLA</abbr>
</a> is ...(definition of Three Letter Acronym)....</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 TLA acronym shows the expanded meaning of the acronym):

A TLA is ...(definition of "Three Letter Acronym")....

If you are creating HTML code that simply expands the acronym then indicate that it is the TLA 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/t/Three-Letter-Acronym/" title="Three Letter Acronym"
onclick="if (confirm('TLA stands for Three Letter Acronym')) return false;"
>
<dfn title="TLA"><abbr title="Three Letter Acronym">TLA</abbr></dfn>
</a> it is the abbreviation for Three Letter Acronym.</p>

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

When we use the acronym TLA it is the abbreviation for Three Letter Acronym.

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.
