Stop a DIV from collapsing when you float elements inside it.Last updated:
Floated divs (
float:left;) don't contribute the the parent container's height, so if you have a parent div with a child div inside, the parent div will collapse (i.e. have it's height down to zero) if you float the child div left or right.
A way to circumvent that is to:
overflow:auto; to the parent container.
