I am selling coffee from Cost Rica. The shopping cart is installed and I started to add products. However, the CSS shopping cart is a stock template. It has nothing to do with a Coffee Theme...yet!
The template has a clean CSS code, and is very well explained.
Bottom line, it is more a matter to give a coffee look than anything else! I mean by that, no changing of layout! Graphics...if you want too.
If you are more on the creative side and do not feel attracted to just add a coffee touch, you are welcome to make any changes you like!
You can see the site at : moncafeducostarica.com. I know it is in French, but the code of the original is all in English.
I have attached the CSS file to show you the code right way. This way, no surprises!
