TeX on blogger

Note to self: if I screw things up customizing the style, the javascript snippet to enable TeX on blogger is:

<script type='text/x-mathjax-config'>
  MathJax.Hub.Config({
    tex2jax: {
      inlineMath: [ ['$','$'], ["\\(","\\)"] ],
      displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
      processEscapes: true
    },
    "HTML-CSS": { availableFonts: ["TeX"] }
  });
</script>
<script async='async' 
  src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-AMS-MML_HTMLorMML'
  type='text/javascript'>
</script>
