Result

Default styling

Though the purpose of this tag is purely for the convenience of the author, its default styling varies from one browser to another:

• Opera, Firefox, Chrome, and some others add a dotted underline to the content of the element.
• A few browsers not only add a dotted underline, but also put it in small caps; to avoid this styling, adding something like font-variant: none in the CSS takes care of this case.

It is therefore recommended that web authors either explicitly style this element, or accept some cross-browser variation.
