find this in your stylesheet:
cartProductDisplay, .cartUnitDisplay, .cartTotalDisplay, .cartRemoveItemDisplay, .cartQuantityUpdate, .cartQuantity, #cartInstructionsDisplay, .cartTotalsDisplay (line 396)
{
padding-top: 0.5em;
padding-right: 0em;
padding-bottom: 0.5em;
padding-left: 0em;
}
and try adding a line for the text color.
More codes to play with:
.tableHeading, #cartSubTotal (line 380)
{
background-color: #e9e9e9; <----change background color here
}
#cartSubTotal (line 384)
{
border-top-width: 1px;
border-top-style: solid;
border-top-color: #cccccc;
font-weight: bold;
text-align: right;
line-height: 2.2em;
padding-right: 2.5em;
}
I'm no expert, but this is where I would start. Make sure you edit a COPY of the css so if this doesn't work for you, your original css is available to go back to.
It may help you to get Firefox and the web developers tool so you can edit the css and see what happens BEFORE you start messing with codes on your live site.
Hope this helps you.
