There are a variety of ways to clear floats with working with html, one way being to create a div with style: clear: both after the last floated element. A more elegant way, when working with Compass, is to use clearfix. Here’s how to go about it.
@import "compass/utilities/general/clearfix" ... .some-element-to-clear-floats-for { @include clearfix(); ... }
