title: box shadow not going over background color of contained element
body: <p>Basically I have a side bar that has an inset box shadow and inside that sidebar is a list of elements whose background color is orange... I would like to be able to make the inset box shadow overlap the background color of the list item.</p>
  
  <p>Here is an image of the desired effect:</p>

  <p>Notice how my inset box shadow isn't going over the orange background? How would I be able to accomlish this?</p>
