[Mailman-Users] Cascading Style Sheets -- Newbie question

[earthlink GHHalley]

Howdy All,

Forgive me for asking what I bet is a simple question.  My webdesigner
is clueless on how this forum works and I'm really busy doing other
work.

Can we use CSS on our Mailman websites?
If so, how?  (assuming general familiarity with Mailman and its setup)
And can we use different style sheets for different lists?

THANKS in advance for your help.  I promise not to ask any more
bone-headed questions.

Peace,
George
