Abbreviation tag
The abbreviation tag is used in HTML 5 to define an abbreviation. What should happen is the abbreviated text is underlined and once the user hovers the cursor over the characters, the complete text is shown in a tool tip. Thus far I have already used an abbreviation and I will use another one describing the CSS involved with abbreviations. This is how I define my abbreviations.
abbr, acronym { border-bottom:.1em dotted; cursor:help; }
Our HTML should look something like the following:
<abbr title="Cascading Style Sheets">CSS</abbr>
This gives our text a dotted underline which I believe works better than a complete underline as these are usually used for links.
