HTML for LEM Acronym

when LEM means Lunar Excursion Module

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 LEM stands for Lunar Excursion Module 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/l/Lunar-Excursion-Module/" title="Lunar Excursion Module"
onclick="if (confirm('LEM stands for Lunar Excursion Module')) return false;"
>
<abbr>LEM</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 Lunar Excursion Module, the meaning of the acronym LEM, 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/l/Lunar-Excursion-Module/" title="Lunar Excursion Module"
onclick="if (confirm('LEM stands for Lunar Excursion Module')) return false;"
>
<dfn><abbr title="Lunar Excursion Module">LEM</abbr>
</a> is ...(definition of Lunar Excursion Module)....</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 LEM acronym shows the expanded meaning of the acronym):

A LEM is ...(definition of "Lunar Excursion Module")....

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

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

When we use the acronym LEM it is the abbreviation for Lunar Excursion Module.

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.
