title: Vertical rule (as opposed to <hr>) in CSS
body: <p>I know it doesn't exist, but is there a pure CSS version?</p>
  
  <p>Would like to set height, and make it 1px wide (with shadow, if possible).</p>
  
  <p>Just cannot fathom a pure CSS way of doing this. Would need to be absolutely positioned.</p>
  
  <p>As my container has two divs side by side, 60-40% split for example. Need the vertical rule between the two, but don't really want to use <code>border-left</code> on div 2.</p>
  
  <p>Any suggestions?</p>
