min height

[whatson]

Is there some code that can make e.g. a div, be a minimum height. e.g. a div must be at least 500px high, but if the content goes further than this, then the div will extend to e.g. 600px?

How far back do you need to go? Current browsers support the basic

{min-height: 500px;}

but MSIE5 doesn't. (I'm on a Mac, hence nothing newer.)
