I've been playing with front-end web design the past couple of days, mainly using floats/clearfix to position my content. I've been marking up the width of the content using % and that has worked perfectly.
However, if I try to define the height as a percentage of the overall page, it fails to work, more accurately it seems to just wrap around what ever content is there and I have to define the height as a px value.
Is there a reason for this? Is there a workaround where I can use a percentage value and it actually divides up the page?
