body: <p>How can I make an inner border using CSS3?</p>
  
  <p>That is, instead of the border extending outwards from the active/padding area of the element, it extends inwards, overlapping its contents?</p>
  
  <p>I'd appreciate it if it could be done with a minimum of CSS rules, if it is possible at all.</p>
