Formatting math equations with MathJax

You can automatically format math equations in your forum posts by adding a MathJax script. This ensures that any LaTeX-style equations posted by members are rendered in a clean, readable format.

Follow these steps to add the MathJax script to your forum:

  1. Log in to your Website Toolbox account.
  2. Click the Integrate link.
  3. Click HTML.
  4. In the Forum Head Tag HTML Code text box, add the following script:
  5. <script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
    <script>
    window.addEventListener("DOMContentLoaded", function(){		
      jQ(window).on('replyPosted postEdited', function() {
        MathJax.typesetPromise();
      });
      MathJax.typesetPromise(); // ensures rendering on page load
    });
    </script>
    
  6. Save your changes.
