Div won't float right_问答_开发者_运维开发者技术经验分享

I have a div that won't float right. When you toggle the visibility it's laid over some of the current text, but I can move that later. Just curious why it won't float right!

You're mixing absolute positioning with floating. If you want to use absolute positioning, just use right: 0; instead of float: right.
Float and absolute positioning tend to fight each other. Try removing the absolute positioning.
