How to change black background on code blocks?

Does anyone know how I can make them look like GitHub code blocks (grey background for example)?

I've tried styling the <code> and <pre> tags using CSS but this doesn't work.

UPDATE If you refresh this page and look at the code block, you'll see that very briefly it shows with a grey background (this is how I'd like it to be). But then after a second the black background style kicks in.
