HTML for UN Acronym

when UN means United Nations

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

A UN is ...(definition of "United Nations")....

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

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

When we use the acronym UN it is the abbreviation for United Nations.

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.
