Reducing signature box height according to signature size

[pigpog]

I'm having trouble with my signature boxes. When you write a short post the signature box takes up a huge amount of the posting space.

You can see on the attachments included where the problem area is. This is dead signature box space. What I want to do is have this space reduced down to where the signature starts.

I've tried adding a height attribute to the sig box code but all it does is give me a set height for everyone's signature box so they all look the same. This is a nice bit of code but, for people with smaller siggies they end up with a huge empty siggy box because it's the same height as the siggy box for someone with a longer signature, for example.

I hope I'm explaining this properly... if you think you can help but need me to try and be more clear I'll try!

This is what I don't want but have now:

98820

This is what I want:

98821

Thanks anyone!

I don't see a difference between the two images.

And, just a personal pet peeve of mine, signatures have gotten WAY out of hand for some folks (which is why I limit them on our site). Signature shouldn't take up more room than a post does IMO. ;)

I've edited the first screenie to bring the height of the dark siggy box down to where the signature starts for the second screenie.

I don't like massive siggies either. Mine is actually the longest we have, since I'm the boss and I have a lot to say! :D

Most of them have one banner or one bit of text, maybe with some dragon eggs thrown in, but that's about it for the majority.
