XF 2.0 How to Put Signature at the Bottom

I'd like to have it so that on posts the member signature is always at the bottom. I tried this but it overlaps once you get more than one paragraph of text in a message.

Code:
.message-signature {
    position: absolute;
    bottom: 0;
}

Any other ideas?
 
Just add some top margin (eg: 40px) to push it down from the message text. Due to the placement of the HTML it's best to use that method rather than absolute positioning to keep it from overlapping.
