==Usage==

This template is to help facilitate the displaying of variable names (in mathematics, computer source code, wikimarkup in template documentation, metasyntactic variables, etc.) with the [[Semantic HTML|semantically correct]] {{tag|var}} tags, which also renders the variable in italics, as is customary. This method is preferred to simply italicizing for many reasons, including [[WP:Accessibility|accessibility]], [[separation of presentation and content]], [[semantic Web]], and [[WP:METADATA|metadata]]; In [[XHTML]] and [[HTML]], the {{tag|var|o}} element has semantic meaning, while simple italicization does not. This template provides a tiny hint of [[kerning]] to compensate for the italicization and enhance readability.
