Forum:Adding CSS classes

Heading
How can I make a heading 2 with a background image of http://images2.wikia.nocookie.net/__cb20111209055428/isleoftune/images/4/4e/Don%27t_Stop_Believing.png using CSS to add to MediaWiki:Wikia.css in Isle of Tune Wiki? Though the file is very large, is it possible to crop it without uploading a new one? Also, I would like it to have those features:


 * Height: 30px


 * Width: 100%


 * Border Radius: 7px

 If anyone has an idea to what this can be like, then please contact me on my talk page   —  Sam Wang  20:43, December 27, 2011


 * Adding something like:

.WikiaArticle h2 {background: url("http://images2.wikia.nocookie.net/__cb20111209055428/isleoftune/images/4/4e/Don%27t_Stop_Believing.png")}
 * would do the job. Although personally I think it looks unreadable. Also, nice sig ;D — Sovq 12:58, December 27, 2011 (UTC)
