CSS 3

CSS 3 is the current version of Cascading Style Sheets (CSS).

It builds upon previous versions of CSS.

Features

CSS 3 features include:

• Rounded corners - see border-radius (CSS)
• Border images - see border-image (CSS)
• Shadows
• Gradients
• Transitions or animations
• Multi-column layout
• Flexible box
• Grid layouts

Availability and behavior of features may vary from browser to browser.

Modules

CSS 3 is divided into several separate documents called "modules".

Each module adds new capabilities or extends features defined in CSS 2, preserving backward compatibility.

The earliest CSS 3 drafts were published in June 1999.

Due to the modularization, different modules have different stability and statuses.

Modules include:

• Media Queries
• Namespaces
• Selectors Level 3
• Color
