HTML for TOS Acronym

when TOS means Terms Of Service

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 TOS stands for Terms Of Service 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/t/Terms-Of-Service/" title="Terms Of Service"
onclick="if (confirm('TOS stands for Terms Of Service')) return false;"
>
<abbr>TOS</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 Terms Of Service, the meaning of the acronym TOS, 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/t/Terms-Of-Service/" title="Terms Of Service"
onclick="if (confirm('TOS stands for Terms Of Service')) return false;"
>
<dfn><abbr title="Terms Of Service">TOS</abbr>
</a> is ...(definition of Terms Of Service)....</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 TOS acronym shows the expanded meaning of the acronym):

A TOS is ...(definition of "Terms Of Service")....

If you are creating HTML code that simply expands the acronym then indicate that it is the TOS 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/t/Terms-Of-Service/" title="Terms Of Service"
onclick="if (confirm('TOS stands for Terms Of Service')) return false;"
>
<dfn title="TOS"><abbr title="Terms Of Service">TOS</abbr></dfn>
</a> it is the abbreviation for Terms Of Service.</p>

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

When we use the acronym TOS it is the abbreviation for Terms Of Service.

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.
