CSS3 is an upgraded version of CSS (cascading style sheet) technology, which was developed in 1999. W3C completed the working draft of CSS3 on May 23,2001.It mainly includes box model, list module, hyperlink mode, language module, background and frame, text special effects, multi-column layout and so on.

A major change in the evolution of CSS is the W3C's decision to divide CSS3 into a series of modules. Browser vendors innovate quickly at the pace of CSS, so by adopting a modular approach, elements in the CSS3 specification can move forward at different speeds, because different browser vendors only support given features. But different browsers support different features at different times, which also complicates cross-browser development.
