HTML for SDTV Acronym

when SDTV means Standard Definition Television

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

A SDTV is ...(definition of "Standard Definition Television")....

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

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

When we use the acronym SDTV it is the abbreviation for Standard Definition Television.

Acronym Vocabulary URI Declaration

<!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.
