HTML for PAL Acronym

when PAL means Phase Alternating Line

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 PAL stands for Phase Alternating Line 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/p/Phase-Alternating-Line/" title="Phase Alternating Line"
onclick="if (confirm('PAL stands for Phase Alternating Line')) return false;"
>
<abbr>PAL</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 Phase Alternating Line, the meaning of the acronym PAL, 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/p/Phase-Alternating-Line/" title="Phase Alternating Line"
onclick="if (confirm('PAL stands for Phase Alternating Line')) return false;"
>
<dfn><abbr title="Phase Alternating Line">PAL</abbr>
</a> is ...(definition of Phase Alternating Line)....</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 PAL acronym shows the expanded meaning of the acronym):

A PAL is ...(definition of "Phase Alternating Line")....

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

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

When we use the acronym PAL it is the abbreviation for Phase Alternating Line.

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.
