Acronyms should be enclosed by the HTML<abbr> tag.
Since an acronym can often have multiple meanings, acronyms used in HTML should be disambiguated to indicate which of the possible acronym definitions is the one that is intended. The easiest way to do this is simply find the term for the meaning of the acronym in the acronym directory, then click on the "usage" link for that term and copy-and-paste the code provided.
<a href="http://www.Acronyms.net/terms/t/Three-Letter-Acronym/" title="Three Letter Acronym"> <abbr>TLA</abbr></a>
You can look up the HTML code for acronyms that you want to use in the Acronym Finder at Acronyms .net.
