title: Issue with Twitter Buttons
body: <p>I'm having this sort of issue with the Twitter button on my webpage. In Firefox Developer Edition, the background of my webpage causes the button to render incorrectly.</p>
  
  <p>example:</p>
  
  <pre><code>#container
  {
      background-color: #f0f1f4
  }
  </code></pre>
  
  <p>causes the text within the button to render white.</p>
  
  <p>Here's how it looks:</p>

  <p>What's up with that?</p>
