useful.styles.js

useful.styles.js is a JavaScript library for loading custom CSS whenever needing it, without refreshing the user's browser.

The library contains three main functions:
- one for adding CSS rules individually
- one for loading entire stylesheets
- one for resetting changes made by the library

These functions can effortlessly be attached to various buttons or controls found on the page, and provide a simple way of loading custom styles, and then resetting them later.

The library can be used for building "preview systems" and "theme selectors."

To help developers get a grasp of all of its functions and capabilities, useful.styles.js comes with a fully-working example.

Requirements:

• JavaScript enabled on client side
