Want to learn how to improve your CSS with the new pseudo-classes? In this lesson, I'll show you how to use the is(), has(), and Where() selectors!

The first thing I'll show you is a website (you can use it) so you can check the compatibility of these and other selectors.

This will give you an idea of whether it's feasible to use them in your projects!

Next, we'll move on to an explanation and some examples of the is(), has(), and Where() selectors in CSS and how they can help you.

The idea is to make writing your code easier by making it more dynamic!
