// Globals
//
// This file is for things that have to apply globally, if your style
// doesn't fit into that description it probably belongs in ui/
// Reset the box-sizing, lifted from bootstrap reboot css, see:
// https://github.com/twbs/bootstrap/blob/bfc16c4a829ba596db28f5f42d7a3e429e6ea2e1/scss/_reboot.scss#L9
//
// 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;`.
