HTML for BTW Acronym

when BTW means By The Way

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

A BTW is ...(definition of "By The Way")....

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

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

When we use the acronym BTW it is the abbreviation for By The Way.

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.
