HTML for UFDs Acronym

when UFDs means USB Flash Drives

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 UFDs stands for USB Flash Drives 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/u/USB-Flash-Drives/" title="USB Flash Drives"
onclick="if (confirm('UFDs stands for USB Flash Drives')) return false;"
>
<abbr>UFDs</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 USB Flash Drives, the meaning of the acronym UFDs, 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/u/USB-Flash-Drives/" title="USB Flash Drives"
onclick="if (confirm('UFDs stands for USB Flash Drives')) return false;"
>
<dfn><abbr title="USB Flash Drives">UFDs</abbr>
</a> is ...(definition of USB Flash Drives)....</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 UFDs acronym shows the expanded meaning of the acronym):

A UFDs is ...(definition of "USB Flash Drives")....

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

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

When we use the acronym UFDs it is the abbreviation for USB Flash Drives.

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.
