mathml-warning.js

This repository contains scripts to display a warning for browsers that do not have good MathML support. This is done by performing MathML feature detection for the <mpadded> element. The user may then ignore the warning or choose a polyfill. The choice will be saved during 30 days in the browser cookie.

You just need to insert one line in your document header:

<html>
  <head>
    ...
    <script src="https://fred-wang.github.io/mathml-warning.js/mpadded-min.js"></script>
    ...
  </head>
  ...
</html>

The english strings are specified in the mpadded.js file. Edit the locales.json file if you wish to add more languages.
