I have set a margin: 0 33% 0 0; however I would also like to make sure the margin is at least a certain px amount. I know there is no min-margin in CSS so I was wondering if I have any options here?
Place a div with a % width and a static min-width to the right of your element.
<div style="position:relative; float:left; margin:0">
<div style="position:relative; float:left; width:33%; min-width:200px">
