title: Color in MathJax
body: <p>I want to display questions on my blog in red in color and answers in blue in color. In questions and answers I am using MathJax 2 to render MathML.
  I am controlling the coloring of MathJax using CSS like this.</p>
  <pre class="lang-css prettyprint-override"><code>h3, h2, h4, h5
  {
      text-align: left;
      font-weight: bold;
      font-family: Verdana;
  }
  
  .question
  {
      text-align: left;
      color: Red;
  
  }
  
  .centerit
  {
      color: Blue;
      text-align: center;
  }
  </code></pre>
  <p>that works perfectly fine in IE, but in Firefox it always displays the MathJax in black color. Is there any workaround to resolve this issue?.</p>
