My goal was for the signatures to always be at the bottom of the post; due to heights of post and the size restriction on the signature, the signature would occasionally have a space between it and the bottom.
After searching for a solution, I have determined that this is impossible with css...
Position absolute breaks the post because the content overlaps on the signature. I tried making them all table cells (using display) but can't apply a max-height to a table cell... Oh css
