Wordpress header.php displaying different CSS depending on page?

Question

I'm currently in the process of converting my website to a wordpress site..and I've run into a problem

My homepage's header uses a different class than my single_page header They uses 2 different css IDs .

Right now I have the homepage which is using inside my header.php but what I want it to do is to display when you're on a page (is_page) How would I do that?

What you need is conditional tags: http://codex.wordpress.org/Conditional_Tags

if (is_page()) { do this }
elseif (is_front_page()) { do that }
else { do nothing? }
