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.
