From The Blog Studio we have Liquid Summer a liquid (resizing based on browser width) three column theme based in some bright blues and greens.
We’ve just added the latest template in our free download series. Liquid Summer was designed and coded by Richard and Mike.
Check it out at www.theblogstudio.com/demo and download it at their Express page.
Unlike some of their other work, I am not really feeling this design, but I am glad its a three column liquid design, so get to customizing it people.
