Title: Code highlighting block - background color visible behind rounding

See the screnshots below:
DIV.highlight is defined in pygments.css, but Boostrap also defines background for PRE.

Ideally CSS selector should only affects div.highligh which have child < pre/>, but I don't know whether it's possible at all.
