Template LoadModule
This is probably the first 3rd Party template, written exclusively for 2008. It won't work on anything else! It is useful for learning the new template system. You can see my point if you publish the template chooser on default Elxis installation, and then switch template to this one. Of course, it's XHTML and CSS valid.
I have created dark template for one reason. That is to show what default css classes should be overridden in your template_css.css, and if you look into index.php, you will see how and where modules are called regardless of their published positions. This template is made for learning purposes, and should be used for quicker adjustment to new template system. I encourage you to experiment with it, and analyze it. I hope it will be helpful.
