I consider myself of intermediate skill level with CSS and PHP, but for the life of me I can't figure out how to remove the tan bar between the navbar and the category/main area.

In a perfect scenario I'd have that background texture moved up to overtake the tan bar so it would flow from the green to the texture.

If you need me to post my CSS files I can do that as well.
