Information box formatting and color

[charlieku]

My information box is located in includes/header.php. I have managed to add pages to it and the links all seem to work properly, but the box contents (text for each link), colors and graphics do not match the boxes for categories and manufacturers (In my case, authors). Where do I go to make the changes needed and how do I do it? (I am very green with php.) Thanks for any help.
