> For example, IE had a completely different interpretation of the CSS box model to everyone else (specifically, how padding, margin and width should interoperate). One interesting outcome of this is we now have the `box-sizing` CSS rule to choose between the original, default box model (content-box) and the IE box model (border-box). Basically every project I've looked into opts into the IE box model.
