3 columns looking bad on mobile

Hi Sakin, I've just recently gone from 2 to 3 columns and it looks great on a computer, but terrible on a small screen. When I had 2 columns only the main content would appear on a small screen which looked great, but with the three column template all three columns get squashed into the smaller screen causing some content to overlap. Is this a bug that is to be fixed or something I can remedy myself? Sarah http://thejuiceplanet.com
