I\'m looking for a solution to fit a child div into it\'s parent\'s width.

Most solutions I\'ve seen here are not cross-browser com

Answer 1

If you put position:relative; on the outer element, the inner element will place itself according to this one. Then a width:auto; on the inner element will be the same as the width of the outer.
