Okey doke site is here

The categories and the information box are the issue i cannot seem to override the css, for the bottom of the boxes, they are currently showing as beige rather than cream (categories), blue (information)

I have successfully over ridden the tops and middles of those boxes, but using the same technique doesn't work for the bases.

The code I am using for the bottom of the category box is

Code:
#categories .leftBoxContainer { 
background-image: url("../images/categories-bottom-cream.jpg");
}
which should work, as I used a very similar code to change the colour of the top
