I was worried someone was going to mention that. The problem for this and the multiquote thing is that part of the issue is that they are dealt with by scripts, which makes it so that it's hard for me to test to make them work better in the background without impacting the regular styles.
Basically I'd need to modify the scripts that just swap out images on click to change the class of the span.
I spent about half the time working on this on trying to figure out the one pixel issue with the thanks button. Annoyingly half the time it all aligns perfectly.
