  /*

  An inner box-shadow casts a shadow as if everything outside
  the padding edge were opaque. Assuming a spread distance of
  zero, its perimeter has the exact same size and shape as the
  padding box. The shadow is drawn inside the padding edge only:
  it is clipped outside the padding box of the element.

  If a spread distance is defined, the shadow perimeter
  defined above is contracted inward (for inner box-shadows)
  by insetting the shadow’s straight edges by the spread
  distance (and flooring the resulting width/height at zero).
