[support] code block style

[Edward]

Hi,

I've just started setting up my own website 
http://www.linuxcrusaders.org with drupal 7 where I'm trying to post 
various linux tips and code as I go along.

I would like the code blocks to appear with a black background and green 
foreground (like a terminal). I tried the geshiphp module, though I'm 
not sure this will accomplish it, and besides which it doesn't seem to 
be quite ready for drupal 7 yet. Therefore, I wondered if anyone could 
recommend another way of achieving this, perhaps editing the css 
stylesheet. I'm not sure if this is also relevant, but I am using the 
Mayo theme.

Thanks for any help.

Ed.
