HTML for RADAR Acronym

when RADAR means Radio Detection And Ranging

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 RADAR stands for Radio Detection And Ranging 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/r/Radio-Detection-And-Ranging/" title="Radio Detection And Ranging"
onclick="if (confirm('RADAR stands for Radio Detection And Ranging')) return false;"
>
<abbr>RADAR</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 Radio Detection And Ranging, the meaning of the acronym RADAR, 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/r/Radio-Detection-And-Ranging/" title="Radio Detection And Ranging"
onclick="if (confirm('RADAR stands for Radio Detection And Ranging')) return false;"
>
<dfn><abbr title="Radio Detection And Ranging">RADAR</abbr>
</a> is ...(definition of Radio Detection And Ranging)....</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 RADAR acronym shows the expanded meaning of the acronym):

A RADAR is ...(definition of "Radio Detection And Ranging")....

If you are creating HTML code that simply expands the acronym then indicate that it is the RADAR 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/r/Radio-Detection-And-Ranging/" title="Radio Detection And Ranging"
onclick="if (confirm('RADAR stands for Radio Detection And Ranging')) return false;"
>
<dfn title="RADAR"><abbr title="Radio Detection And Ranging">RADAR</abbr></dfn>
</a> it is the abbreviation for Radio Detection And Ranging.</p>

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

When we use the acronym RADAR it is the abbreviation for Radio Detection And Ranging.

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.
