The new XDA forum design has just been launched to the public, but if you prefer the old layout design and not the colours, there is an alternative available.
XDA forum member khaytsus, designed his own alternate CSS theme for the forum way back in 2009 providing three themes – blue, grey and dark grey for XDA members who fancied a change from the old yellow and brown colours.
The site theme uses Stylish, the Firefox CSS add-on which lets you easily install themes and skins for websites. khaytsus’s themes narrow the page size to 1200 pixels but this is can be easily edited. Requires FireFox, Stylish add-on, Greasemonkey add-on (lets you install scripts to make changes to web pages which are executed each time the page is opened), or Opera.
To try out khaytsus’s themes, check out the forum thread, and take your time to browse through as there are also other member’s contributions posted in the main body of the thread._________
