Difference Between CSS and CSS3

CSS stands for Cascading Style Sheets.
CSS describes how HTML elements are to be displayed on screen in the browser.
CSS controls the layout of multiple Web pages all at once.
External Style Sheets are stored in CSS files.


CSS3 is the latest standard for CSS.
CSS3 is completely backwards-compatible with earlier versions of CSS.


The biggest difference between CSS2 and CSS3 is that CSS3 has been split up into different sections, called modules. In addition to the existing old modules, the new modules have been added. The CSS3 version supports many more browsers than CSS.


Other major changes/additions include:

• New Combinator
• New CSS Selectors
• New Pseudo-elements
• New Style properties
