title: How to insert a line break before an element using CSS
body: <p>I feel like I saw a way, using the CSS content property, to insert a line break tag before an element. Obviously this doesn't work:</p>
  
  <pre><code>#restart:before { content: '&lt;br/&gt;'; }
  </code></pre>
  
  <p>But how do you do this?</p>
