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:
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');
