Introduction

In the previous section, we looked at basic selectors like tags, classes, IDs, group selectors, and the universal selector. These gave you the tools to start styling elements on the page.

Now we’re stepping things up a bit. In this chapter, you’ll learn some smarter ways to target elements—specifically the descendant selector (to style an element only if it’s inside another) and the adjacent sibling selector (to style an element only if it’s right after another).

These techniques make your CSS cleaner, more flexible, and easier to manage as your projects grow.
