Pseudo-Class and Custom Selectors
Understand built-in pseudo-classes like :has(), :not(), and :nth-child(), then learn to create your own custom selectors for reusable element filtering.
Unlock Power with Pseudo-Classes
Welcome to Advanced Selectors! Today, we'll explore pseudo-classes, special keywords added to selectors to define a special state of the selected element.
- They let you target elements that aren't easily selected by standard HTML attributes or names.
- Think of them as dynamic filters for your selections.
They start with a colon (:), like :hover or :first-child.
Target by Position: :nth-child()
The :nth-child() pseudo-class selects elements based on their position among a group of siblings. It's incredibly useful for styling lists or table rows.
:nth-child(n): Selects the nth child.:nth-child(odd): Selects odd-numbered children.:nth-child(even): Selects even-numbered children.
The counting starts from 1 for the first child.
