title: How to set the border per side for an input box?
body: <p>The <code>input-box</code> comes with an outline that can be set to <code>0</code>.
  It will then show an ugly border around it.</p>
  
  <p>This border can be set to <code>none</code> as well, leaving the input box without a border.</p>
  
  <p>However I'd like to put a border only on the top and bottom of the input box, but can't get it done. 
  Any ideas?</p>
