title: Font awesome 5 on pseudo elements
body: <p>In font awesome 4 you could easily apply an icon to a :before/:after element using CSS.</p>
  
  <p>Is the same possible with the new font awesome 5 JS/SVG implementation? As from what i can see this requires the relevant  tag to exist in html which isn't always practical e.g. you have a CMS and want to apply an icon to all user created content <code>&lt;li&gt;</code> elements</p>
  
  <p>I know in FA5 you can still use the old css/webfonts but it would be nice if the same functionality was available in the recommended method of using JS</p>
