benefit is a utility CSS-in-JS library that provides a set of low-level, configurable, ready-to-use styles. These styles are generated for you as you use them, so you don't have to worry about including stylesheets or eliminating unused styles.
Here, we are applying 5 utility classes to a <div>. Click any class to remove it and try adding some new ones (like bg-pink-400 or italic).
As the class names are interpreted, style rules are inserted into your markup and cached for another element to take advantage of. This way, any utility only gets inserted once.
Let's start off with an unstyled <div> with some alert content. The goal is for us to make this look like an error that is displayed to the user.
