Blocks at the bottom of the page are unclickable

After "show answer", I sometimes have many blocks, which extend to the bottom of the page. In this case, I can't click the blocks where they intersect with the button area. Could possibly be fixed by adding some margin at the bottom of the appropriate div.

Not sure... The response area is just plonked on top of everything. Better practice would be not having so many blocks. :D Will consider though.
