title: Changing mathjax's font size
body: <p>I am using mathjax on my page, and i have read that this:</p>
  
  <pre><code>&lt;script type="text/x-mathjax-config"&gt;
    MathJax.Hub.Config({
      "HTML-CSS": { scale: 175}
    });
  &lt;/script&gt;
  </code></pre>
  
  <p>Is supposed to make fonts bigger. But instead, all it does, is that it makes the container of mathjax equations bigger, but the fonts stay the same. Why is that? How to change font size?</p>
