Sugar is a free theme for XOOPS that supports 3 columns.

It features various modern techniques for the website which include:
* Rounded corners using CSS3 (no fallback for IE or unsupported, degrades gracefully)
* RGBA shadow for the avatars in the forum
* Alpha transparency when hovering over an image

It also includes custom PNG buttons for newbb as well as PSDs to make the theme easily modifable.

The buttons for newbb use the ElegantIcons released by Nick from ElegantThemes ( http://www.elegantthemes.com )
The other graphics in this theme are the famous Silk icons by FamFamFam ( http://www.famfamfam.com ) as well as a photoshopped background by me.

This theme has been created using the blank theme by Kris_Fr.

The theme has been tested in Opera 10.60, Mozilla Firefox 3.6.6, Chrome 5.0.375.99 and Safari 5. It also renders properly in IE9 PP, but in the current IE8 and below there are a few errors including the not rendering of the rounded corners, RGBA shadow or alpha transparancy on the logo (this works, but gives a less nice effect).

Demo can be found on http://demo.vampiretrix.com/xoops and you can download it from my blog on http://www.vampiretrix.com/note/sugar-theme-ready

Have a nice day,
