Here is what I did…
Add this to your style.css
#main { float: left; margin-left: 0; }
#sidebar { clear: left; }
#sidebar-right { margin-left: 3%; padding-left: 2%; float: right; margin-top: 20px; }
@media only screen and (max-width: 2000px) {
#sidebar-right { width: 30%; }
}
At the top of page.php – take out the clearfix and add col620
<div id=”content” class=”clearfix”>
<div id=”main” class=”col620″ role=”main”>
On your sidebar page – Remove clearfix and add col300
<div id=”sidebar-right” class=”widget-area col300″ role=”complementary”>
This worked for me in every browser except ie7 & ie8, still trying to figure that out. Hope this helps!
