There is something that I need to do using HTML and CSS, without javascript.
I need help to define the css of "Outer Div". It has to go all the way to the bottom of the page. The height has to be 100% - 90px. The header has a fixed height. Inner Div's height has to be 60% of the height of Outer Div. Can anyone help me? I can use html5 or css3 if needed.
