Dynamic Styles: Introduction to CSS Pseudo-Class Selectors
CSS pseudo-classes allow you to apply styles to elements based on their state or position in the document.
Syntax
The basic syntax for using a pseudo-class in CSS is: selector:pseudo-class { /* styles here */ }
Some common pseudo-classes include: :hover, :focus, :nth-child(), and :first-child.
Purpose
Pseudo-classes are fundamental for applying conditional styles. With them, you can:
- Change the color of a link when the user visits it.
- Apply styles to an element that receives focus.
- Style the first item in a list.
