title: Undesired background color overlay while using brunch/with-react
body: <p>I am not sure this issue is related directly to brunch, but it's the first time I use this framework and first time I see something like this ...</p>
  
  <p>I am trying out brunch/with-react skeleton and there is a little issue with my DOM elements.</p>
  
  <p>I changed my body's background color as follow, in <code>app/styles/application.css</code></p>
  
  <pre><code>body {
    background-color: #cfcfcf
  }
  </code></pre>
  
  <p>Here is the result
  <a href="https://i.stack.imgur.com/ZdTjI.png" rel="nofollow">DOM rendering</a></p>
  
  <p>I am using Chrome so I went ahead and inspected every elements. 
  I cannot find any element responsible for this behavior.</p>
