HTML Tag Reference - HTML tag <abbr>
This element allows authors to indicate a sequence of characters that defines an abbreviation for a word.
The <abbr> tag marks abbreviation or acronym, like "UN" or "USA".
This tag is commonly confused with <acronym>.
While Web developers appear to use an <acronym> tag more often than an <abbr> tag,
the former is deprecated under HTML5! The confusion continues.
According to the HTML5 specification, the title attribute should be set to the expansion of the abbreviation.

class="class name(s)"
