HTML for DES Acronym

when DES means Data Encryption Standard

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 DES stands for Data Encryption Standard 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/d/Data-Encryption-Standard/" title="Data Encryption Standard"
onclick="if (confirm('DES stands for Data Encryption Standard')) return false;"
>
<abbr>DES</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 Data Encryption Standard, the meaning of the acronym DES, 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/d/Data-Encryption-Standard/" title="Data Encryption Standard"
onclick="if (confirm('DES stands for Data Encryption Standard')) return false;"
>
<dfn><abbr title="Data Encryption Standard">DES</abbr>
</a> is ...(definition of Data Encryption Standard)....</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 DES acronym shows the expanded meaning of the acronym):

A DES is ...(definition of "Data Encryption Standard")....

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

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

When we use the acronym DES it is the abbreviation for Data Encryption Standard.

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.
