CSS3 gradient faux column
This faux column is created by a CSS3 gradient. The two colors of the gradient are given the same number (pixel or percent value) to stop at. Thus, they don't blend at all and a hard edge is created.
background-image: -webkit-gradient(linear, 35% 100%, 35% 100%, from(#E2DAED), to(#FFFFFF));
background-image: -moz-linear-gradient(35% 0% 180deg,#FFFFFF, #E2DAED, #E2DAED 0%);
