// Reset the box-sizing, lifted from bootstrap reboot css, see:

// Change from `box-sizing: content-box` to `border-box` so that when you add
// `padding` or `border`s to an element, the overall declared `width` does not
// change. For example, `width: 100px;` will always be `100px` despite the
// `border: 10px solid red;` and `padding: 20px;`.
