Editing appearance of main menu
How can I change the appearance of the main menu in Joomla?
I've been playing around with the CSS, but seemingly to no effect.
Our website can be found here. Currently having issues with our host, so apologies if you timeout.
Basically, I would like to move the menu down to the next line, directly beneath the current logo, and expand the logo all the way to the right. I would also like to change the current colours of the menu to liven it up a bit.
Could anyone point me in the right direction, or tell me how to do this?
