Hello everyone,

I have searched and researched for a while now but I have a simple question to start

I have built my site in HTML with CSS and was originally going to use simply Paypal to checkout and pay. Now I have been lured in by the idea of having customers register and log in just for their ease.

Is there a way to incorporate my already written code with Zencart(or another cart if need be) so that I do not need to use the templates and so I havent wasted time building this. I really like what I have written but was wondering how easy or impossible this could be

Any links or information otherwise is very appreciated.

Thank you all very much in advance.
