title: How do I uncollapse a margin?
body: <p>Collapsing margins in CSS: <a href="http://www.w3.org/TR/CSS21/box.html#collapsing-margins" rel="noreferrer">http://www.w3.org/TR/CSS21/box.html#collapsing-margins</a></p>
  
  <p>I understand the <a href="https://stackoverflow.com/questions/1438114/for-what-reason-margin-collapse-rules-were-introduced-in-css">purpose of the feature</a>, but I'm trying to do layout, and I can't figure out how to turn it off.</p>
  
  <p>The way usually explained in CSS tutorials is to either:</p>
  
  <ol>
  <li>Add a border</li>
  <li>Add a padding</li>
  </ol>
  
  <p>All of these have side effects that become obvious when you're dealing with pixel-perfect layouts with background images and fixed paddings. </p>
  
  <p>Is there any way to simply disable the collapsing without having to shove extra pixels into the layout? It doesn't make any sense for me to have to visually affect the document to change behavior like this.</p>
