How do i set a default font? + menu question

[ianaddisonuk]

Firstly, thanks to everyone for their help, our site is coming along nicely!

 

I was wondering whereabouts (and in which file) can i set the site's default font? I would like every article written in Tahoma size 11. But I cant seem to do it anywhere.

 

also...i am using rokwebify orange, and above the menus, the title e.g. curriculum menu, parents menu is pink. How/where do i change the colour? I would like to change it to black, im sure its in a css file somewhere, but not sure where!

 

any suggestions?
