title: Is there a way to add overlapping borders to ALL div with css?
body: <p>I did a search here but I found just info about adjacent borders. Does anybody know if it is possible to add borders to all divs just to see how the current layout works.</p>
  
  <p>If you just add a 1px border, it will add 2px to the width (side by side) and will - sometimes - break the current layout.</p>
  
  <p>I need this just for control purposes, something to turn on/off, not for production.</p>
  
  <p>thanks!</p>
