    Prevent CSS Class Name Collisions with Scoped Class Names in CSS-in-JS


    Currently, CSS has no standardized and well-supported way to scope class names. By default, CSS selectors have one global namespace. This works fine as long as the code base is small, but when it grows and more than one person works on it, it becomes increasingly hard to manage selectors. This is the reason why many naming conventions like BEM, SMACSS, OOCSS have been created.

    We will learn how to make sure our class names have no collisions without using a naming convention. By doing this, we will have created our own minimalistic CSS-in-JS library.
