I am trying to use css to position two div's, one directly above the other. This usually works fine except the height of the div on top has a dynamic height as content is added or taken away using javascript. Inside of that div I have a series of other div's but the parent div does not expand to cover the ones inside of it. I need a way to make the div on top expand in size to cover every child it has.
And help or alternate solutions would be awesome.
This is most likely caused by having floated elements inside of your div. You can either add a clearing div at the end of its contents with style clear:both; or add overflow:hidden; to the dynamic height div
