// Reboot
//
// Global resets to common HTML elements and more for easier usage by Bootstrap.
// Builds on the resets of Normalize.css.


// Reset the box-sizing
//
// 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;`.
//
// Heads up! This reset may cause conflicts with some third-party widgets. For
// recommendations on resolving such conflicts, see
// http://getbootstrap.com/getting-started/#third-box-sizing.
