title: Is it possible to use MathJax on squarespace?
body: <p>I am currently attempting to create a new website using squarespace, and I'd like to use <a href="http://www.mathjax.org/">MathJax</a> to typeset mathematics.  This is the same engine used by SE to render mathematics on physics.SE for example.  </p>
  
  <p>The standard way of using MathJax is to put a certain code snippet in the header of the page one which you would like to use MathJax as outlined <a href="http://docs.mathjax.org/en/latest/platforms/index.html">here</a>.  I have attempted to do this in squarespace by using the "code injection" feature that allows one to put desired code into the header of all pages on a squarespace site, but the mathematics doesn't seem to be rendering.</p>
  
  <p><a href="http://streylab.com/blog/2013/8/13/mathjax-in-squarespace-6">This person</a> alleges to have made the procedure I outline above work, but after entering the desired mathematical formulas into an HTML code block as he suggests, MathJax does not seem to be working.  Below is a code sample.</p>
  
  <p>JavaScript:</p>
  
  <pre><code>&lt;script type="text/javascript"
     src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>HTML:</p>
  
  <pre><code>When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are
  $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
  </code></pre>
  
  <p><strong>Update.</strong> It seems as though MathJax does actually render properly using the procedure outlined above (namely if you enter it into an html code block), but ONLY if you are viewing the site as a visitor, and not while you are logged into your squarespace account. </p>
