Abbreviations and Acronyms

Ideally, the <abbr> tag should be used any time that you have an abbreviation or an acronym. At the very least, it should be used the first time you introduce an uncommon or non-obvious acronyms or abbreviations.

Whenever the <abbr> tag is used, you should always use the title attribute, which indicates the meaning of the abbreviation or acronym.

Deprecated `<acronym>` tag

Older HTML specifications included a separate <acronym> element. This has now been deprecated in HTML5, and acronyms should be marked up with the <abbr> element instead.

The `<dfn>` element

If you are using an unfamiliar or unusual abbreviation, you may want to consider also including a <dfn> element so provide additional information about the word or phrase.
