For example I have a CSS selector:
#spotlightPlayer .container .commands.over span,
#spotlightPlayer .container .commands.over ul,
#spotlightPlayer .container .c
You might check out Sass. It has a lot of helpful little features that let you make your style sheets more declarative than the normal CSS syntax allows. It handles deeply nested tags in a very natural way. In Sass, this would be:
#spotlightPlayer .container. commands.over
span, ul, ul li
:clear both
