Uninson.js.

Unison.js is a very small script (less than 1KB after compression), allowing us to declare breakpoints only once, but these breakpoints can be used for both JavaScript and markup. It requires a preprocessor, such as sass, less, and stylus to perform functions. And, in the background, it uses the Font-family properties and caption tags that are located on the head of the page to store the information. Its debugging features allow you to print breakpoints for easy access.
