Oh you were sooooooooooooo close! Here is the one piece of css you need to change:

Code: Select all

#content {width: 520px;
        height: 100%;
        float: left;
        clear: right;
        font-family: Arial, Verdana, sans-serif;
        padding-top: 15px;
        padding-bottom: 15px;
        border-right: 2px solid rgb(255,0,153);}

By getting rid of the margin-right: 260px you have now allowed the sidebar the ability to move up.
AND by reducing the width of this div to 520px instead of 526px, you now have room for both to sit side by side!
