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.
In a browser:
<script src="css.escape.js"></script>Via npm:
npm install css.escapeThen, in Node.js:
require('css.escape');| Mathias Bynens |
