Template:Var/doc

Usage
This template is to help facilitate the displaying of variable names (in mathematics, computer source code, etc.) with the semantically correct, which also renders the variable in italics, as is customary. This method is preferred to simply italicizing, for accessibility, content/presentation separation, semantic Web, and metadata reasons; XHTML's  element has semantic meaning, while simple italicization does not.

Example:



outputs



which renders as:


 * username

compare to simple  italicization:


 * username
