title: Use a CSS Class to Style an Element
body: <p>I'm currently learning how to code on freecodecamp.com, and I'm having difficulty successfully using a CSS class to a style an element. Specifically, changing the text CatPhotoApp from red to blue.  I've followed the instructions on the page, and this is what I've done so far:</p>
  
  <pre><code>&lt;style&gt;
    h2 {.blue-text
    color: blue;
    }
  &lt;/style&gt;
  
  &lt;h2&gt;CatPhotoApp&lt;/h2&gt;
  
  &lt;p&gt;Kitty ipsum dolor sit amet, shed everywhere shed everywhere stretching   attack your ankles chase the red dot, hairball run catnip eat the grass sniff.&lt;/p&gt; 
  </code></pre>
  
  <p>Am I missing a step?</p>
