Overview

CSS3 is the latest version of the CSS standard. Unlike CSS2, which was a single large specification, CSS3 is divided into several separate modules, allowing for faster updates and better browser support for specific features.

Key Modules

  • Selectors: Advanced ways to target elements (e.g., :nth-child, [attribute]).
  • Box Model: Enhancements like box-sizing and flexible box layout.
  • Backgrounds and Borders: Support for rounded corners, gradients, and multiple backgrounds.
  • Animations and Transitions: Native support for smooth visual effects without JavaScript.

Benefits

CSS3 allows for more complex and visually appealing designs with less code, improving performance and maintainability.
