Seems one of these things hits the front page every month or so. My question is, why don't the browser makers adopt something like this as the default stylesheet? Are they constrained by the spec here or is it just a matter of inertia?
Probably part of this CSS is something like reboot or reset which will try to paper over the remaining differences between different browsers, I think the browsers probably are converging in that regard but IE11 and backwards compatibility still make them necessary.
