A bunch of bugs to take care of if you're going to target legacy IE browsers.

IE8: ‘change’ event

The ‘change’ event doesn’t always fire. Not for checkboxes, radios, multi-select lists. Use the click handler instead.

IE8: label with input

Clicking label with input inside doesn’t focus the input.

IE8: Opacity propagation

An element’s ‘opacity’ value isn’t propagated to its positioned descendants.
