<p dir="auto">Challenge <a href="http://beta.freecodecamp.com/en/challenges/basic-css/change-the-color-of-text" rel="nofollow">change-the-color-of-text</a> has an issue.<br>
User Agent is: <code class="notranslate">Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0</code>.<br>
The challenge says that to pass, the h2-element has to be red. As you see further down, it is. The preview shows the h2 to be red. But the tests fail with the message: "Your h2 element should be red."</p>
