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');
// On Windows and on Mac systems with default settings, case doesn’t matter,
// which allows you to do this instead:
require('CSS.escape');
