X-Cart forums - Changing Out of the Box Layout (TPL/CSS) in Xcart 5.1

I have been using previous versions of X-cart for quite a few years and have been able to figure out customizations for a lot of the previous 3.x and 4.x versions that we have needed over time.

But the set up in 5.1 is a bit more widespread as everything isn't as easily available with upfront .tpl files now.

I am looking to do a bit more "out of the box" style editing in moving layouts around, but I am on a bit of a time crunch, so I'm not able to really spend days in dissecting the cart at current.

Does anyone have any start up tips or pointers that might help so I can dive right in?

Mostly looking in starting out where the body layout, sidebar and header options would be as I can't seem to find one file that really can help edit them like previous versions.

Thanks in advance!!
