CSS.escape polyfill

A robust polyfill for the CSS.escape utility method as defined in CSSOM.

For a more powerful alternative, consider using cssesc, which automatically takes care of excessive whitespace, and has many options to customize the output.

Installation

In a browser:

<script src="css.escape.js"></script>

Via npm:

npm install css.escape

Then, in Node.js:

require('css.escape');
