What is CSS3?

Cascading Style Sheets (CSS) is a style sheet language used to illustrate the look and format of a document written in any markup language. It is used to style and organize the layout of Web pages. The latest version of CSS, CSS3, builds on earlier versions of CSS by adding new features that make the language more powerful and flexible.

The CSS3 specification adds new features to the CSS, including animation and transitions, as well as support for responsive design. It also provides more selectors, allowing web designers to select specific elements on a web page quickly.

Some of the major modules of CSS3 are:

• Box model
• Image values and replaced content
• Text effects
• Selectors
• Backgrounds and borders
• Animations
• User interface (UI)
• Multiple column layouts
• 2D/3D transformations
