I set config by https://revealjs.com/math/, MathJax2 could work but not KaTeX

Here the Minimal Config

<html>

<head>
  <link rel="stylesheet" href="dist/reveal.css">
  <link rel="stylesheet" href="dist/theme/white.css">
</head>

<body>
  <div class="reveal">
    <div class="slides">

      <section>
        <h2>The Lorenz Equations</h2>
        \begin{aligned}
        \dot{x} &amp; = \sigma(y-x) \\
        \dot{y} &amp; = \rho x - y - xz \\
        \dot{z} &amp; = -\beta z + xy
        \end{aligned}
      </section>

    </div>
  </div>

  <script src="dist/reveal.js"></script>
  <script src="plugin/math/math.js"></script>
  <script>
    Reveal.initialize({
      plugins: [RevealMath.KaTeX]
    });
  </script>
</body>
</html>

RevealMath.MathJax2 could work，In Examples files there is only Mathjax2 , So I have no diea to figure it out which part get wrong.

Hey! Two issues;

  1. KaTeX requires a doctype, so you'll need <!DOCTYPE html> at the top.
  2. You'll need to wrap your math with a start/end delimiter (\[ math_here \] or $$ math_here $$). These are listed under the KaTeX config in the docs.

Here's a working example with the above changes;

<!DOCTYPE html>
<html>

<head>
  <link rel="stylesheet" href="dist/reveal.css">
  <link rel="stylesheet" href="dist/theme/white.css">
</head>

<body>
  <div class="reveal">
    <div class="slides">

      <section>
        <h2>The Lorenz Equations</h2>
        $$
        \begin{aligned}
        \dot{x} &amp; = \sigma(y-x) \\
        \dot{y} &amp; = \rho x - y - xz \\
        \dot{z} &amp; = -\beta z + xy
        \end{aligned}
        $$
      </section>

    </div>
  </div>

  <script src="dist/reveal.js"></script>
  <script src="plugin/math/math.js"></script>
  <script>
    Reveal.initialize({
      plugins: [RevealMath.KaTeX]
    });
  </script>
</body>
</html>
