YOu said: "2 totally different sets of html - one for the homepage solely, and then another with variations for all other pages" and "Not sure exactly what you're trying to accomplish."
(1) I am trying to have a home page that is different from the rest of the cart in terms of (a) what is displayed in the center section -- I have succeeded in this -- and (b) by being a fixed-width page--the _only_ fixed-width page in the cart.
(2) If having two differetn sets of html would solve (1)(b) above, then please provide advice on how to do this. If you can help me achieve a fixed-width home page in some other way, I am all ears!
Here is the current home page:
http://www.bitsbytescomputer.com/store/customer/home.php
The content of the center section and the right hand column are both in one tpl that is called by an include statement from customer/main/welcome.tpl.
Thanks in advance for your help!
