This tag is commonly confused with <acronym>. Debate about just what constitutes an acronym as compared with an abbreviation is common amongst very detail-oriented Web standards experts. In reality,Web developers appear to use the <acronym> tag more often than the <abbr> tag.

With the title attribute set on this element, Opera and Mozilla may render a dotted underline useful to suggest the Tooltip that might contain a definition for the word.

Because there is typically no markup-oriented presentation for this element, it is primarily used in conjunction with style sheets and scripts.
