In my limited experience I find CSS examples always make things look simple, but then in reality I'm forced to do something stupid like this for a 400px canvas:

            left: 50%;
            margin-left: -205px;
            border: 0px;
            width: 410px;

Because when sized to 400px it always clips 10 pixels of the canvas.

i'd have to poke around to be sure, but i have a suspicion:

    box-sizing: border-box;
    width: 400px;

might be the fix for that scenario
