title: How do I use different themes for open street maps in open layers?
body: <p>I have a map application with custom interactive layers, but I want to use the dark theme from <a href="https://openmaptiles.org/styles/" rel="nofollow noreferrer">this</a>. I'm using <a href="https://jsfiddle.net/ju86qb17/" rel="nofollow noreferrer">playing around on jsfiddle</a> and I just can't seen to get the dark theme to work. I tried this:</p>
  
  <pre><code>      new TileLayer({
          source: new TileJSON({
            url: 'https://raw.githubusercontent.com/openmaptiles/dark-matter-gl-style/master/style.json'
          })
        })
  </code></pre>
  
  <p>I'm using classic apache and php. I have no clue about npm and webpack.</p>
