to

 min-height:400px;

Perhaps changing "height" and "min-height" may be more suitable?

@cez :- Thanks I edit my answer so that it expands vertically as well as horizontally.

I can't imagine why you'd want it to expand horizontally?

I have a main tag with min-height set and no height, and has div children, but main is not expanding to contain the children. Instead, the children are just overflowing. The footer is at the top of main's content because main's actual size is tiny.
