title: Flexbox align-content and justify-content not working
body: <p>I set specific widths and I don't have <code>margin: auto</code> on my flex items, but for some reason these properties are not working as expected.</p>
  
  <p>I just want spacing between the headbox and the list classes.</p>
  
  <p>Now on my com the headbox is centered but on the snippet is not, and I am not sure why, even though <code>justify-content</code> is set to center.</p>
  
  <p>But even on my computer <code>align-items</code> is not working as it should.</p>
  
  <p>I mean I know it has no effect but that's just if there's only one item.</p>
  
  <p>I've also commented out some of the usual suspects but that isn't working.</p>
  
  <p>Lastly, <code>right</code> is actually a part of a bigger container div but that should be irrelevant. If you do a fullpage for the snippet you'll see what I am talking about.</p>
