I have implemented support for min-height and max-height. The footers example on alistapart works now. I've also been fixing bugs with table cells and percentage height children, so that elements inside cells with percentage heights will flex properly. I still haven't done min/max-width/height for positioned elements though. That's all that remains, and then support for it will be complete. [More]
