MARKTECH  This is a great bit of software. Once I'd figured out the x-ray and inspector functionality it all snapped into place. As a relative newbie to CSS I'd been struggling with templates and trying to adapt them to my own use. This software made it really obvious what tags applied to what content and made it easy to edit. You can instantly see the results of any changes you make and this helps you understand the CSS itself. Would be great for CSS from scratch as well.

There's not a huge amount of functionality in the software, but what there is works great after a short learning curve.
