Color - Behind my Cart

[Hoodgrown]

If you look on my site.. you'll see my sidebar cart is black
http://www.petsright.com

but the more products you add.. the grey starts to show...

where in the css file can I change this?

Line 928 of your css file, change the colour hex code to #000

line 928 of the global css file in my theme is:

div.exclusive, div.exclusive a { color: white; }

What about this block of code?

/* block top user information */
#header #header_user {
   width: 99%;
   text-align: right;
   clear: left;
   margin:0.6em 0.6em 0 0;
}
#header_user p { color: #595a5e; }
#header_user span { font-weight: bold; }
#header_user ul { margin-top: 0.3em; }
#header_user li {
   float: right;
   line-height: 2em;
   margin-left: 0.5em;
   white-space: nowrap;
}
#header_user #shopping_cart, #header_user #your_account { font-size: 0.9em; }
#header_user #shopping_cart a, #header_user #your_account a {
   background-repeat: no-repeat;
   background-position: top left;
   padding: 2px 0 4px 26px;
   height: 20px;
   text-decoration: none;
}
#header_user #shopping_cart a { background-image: url('../img/icon/cart.gif'); }
#header_user #shopping_cart span.ajax_cart_quantity { padding-right:0.5em; }
#header_user #your_account a { background-image: url('../img/icon/my-account.gif'); }
