Two Column Masonry JQuery With Different Width?

I am current working on a custom theme using Masonry. I successfully implemented masonry but i unfortunately, i can't figure out how can i implement a two column with different siz

Solution 1:

i guess the work around will be as follows

$('.col2').css({'width':400});
$('.col1').css({'width':250});

after you apply the plugin . and edit other proprieties if required
