![]() ![]() That means MathJax v3 is not a drop-in replacement for MathJax v2, and upgrading to version 3 takes some adjustment to your web pages. MathJax v3 is a complete rewrite of MathJax from the ground up, and so its internal structure is quite different from that of version 2. I tried simply swapping out the src for the newer version, but this did not work, because it seem that MathJax 3 uses an entirely new syntax than 2.x. But MathJax 2 is a lot slower than MathJax 3 or KaTeX. The page above includes all the necessary code snippets to implement this for MathJax 2.x. Add a pseudo-callback to MathJax which waits until typesetting is complete, then runs a piece of javascript to add the above class to all the parent element of all MathJax elements.Add a class has-jax to your CSS which undoes whatever code-specific formatting your website uses.Configure MathJax to attempt to typeset within blocks (which it skips by default).The best general approach seems to be this one: So if your page contains multiple underscores, your LaTeX code will be broken before the page even starts loading. ![]() However the underscore is frequently used in LaTeX for subscript. The markdown parser interprets underscores ( _) as italics, and so it removes them and wraps the enclosed text in the appropriate HTML tags. The problem is that the initial page contents have already been processed by Hugo’s markdown engine before the page even loads. While the page is loading in a visitor’s browser, the library processes text enclosed in dollar signs and, renders it as LaTeX and replaces the contents of the page. Typically, you embed a javascript library such as MathJax or KaTeX by adding a line of HTML to your website template. It is great for a number of reasons (speed, simplicity) but one area where I find it lacking is in its support for math typesetting. This blog runs on Hugo, a publishing framework which processes markdown text files into static web assets which can be conveniently hosted on a server without a database. ![]()
