Code
/* Custom */
@media all and (max-width:899px) {
.left_col{display:none;}
.body_col{padding:0;width:100%!important;}
}
Just add this to the bottom of your style in the "Extra" section (we would advise against modifying common.css), it will hide the left column

If you want it to hide both columns just:
Code
/* Custom */
@media all and (max-width:899px) {
.left_col{display:none;}
.right_col{display:none;}
.body_col{padding:0;width:100%!important;}
}

Keep in mind though that users with a browser width of 900px or less will get this behavior, desktop laptop or (god forbid) phone.
