title: Append Divs to Container and keeping them in a horizontal line
body: <p>I have a container DIV that is resizable. I allow the user to add DIV elements to it, to create some sort of a playlist. When the container DIV is not large enough for a content DIV to be appended, I want the content DIV to just get cut off at the end of the container DIV. Unfortunately it always gets appended underneath other content elements. I tried <code>overflow:hidden;</code> for the container element, but that didn't have any effect...</p>
