Re: Rounded corners and transparency
It depends on what you want enclosed in a round-corners box. In the case of module boxes, you have to add the spiffycorners HTML to your theme's module.tpl file, more or less at the beginning and the end of the file.
As for the center of the page, you could add the HTML to tiki.tpl so that {$mid) is surrounded. This would be a start for experimenting, anyway.
Of course the corners CSS needs to be added to the theme CSS file.
The Zuka theme uses a similar technique for its borders, based on the 456 Berea Street method.
