// The default value is `padding-box` -- the box model used by modern browsers.
//
// If you wish to do so, you can override the default constant with `border-box`
//
// To override to the default border-box model, use this code:
//     $default-background-clip: border-box

$default-background-clip: padding-box !default;

// Clip the background (image and color) at the edge of the padding or border.
//
// Legal Values:
//
//   * padding-box
//   * border-box
//   * text
