This is a spring theme based on a 960px wide 16 columns grid.
The main content can either be two or three columns while the footer can either be three or four columns.
I've played with this cat in all popular browsers including Internet Explorer 6 but because I have extensively used advanced CSS it looks sharpest in the funky browsers such as Firefox, Safari and Chrome.
The only extra JavaScript is that to hustle the 24 bit PNGs into action in IE6.
You can download the two main images as Photoshop files here.
In order to see The Rite of Spring you may need to use the theme switcher on the live demo site linked to below.
Peace, love and prosperity
