What is CSS3?

CSS is the abbreviation of Cascading Style Sheets (cascading style sheet). It is a computer language used to represent file styles such as HTML (an application of standard general markup language) or XML (a subset of standard general markup language).

CSS can accurately control the layout of elements in a web page at the pixel level, support almost all font size styles, and have the ability to edit web objects and model styles.

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.

The principle of CSS3, like CSS, is to customize the selector of a stylesheet in a web page, and then refer to a large number of these selectors in the web page.

New features

There are many new features of CSS3, such as fillet effects, graphical boundaries, block shadows and text shadows, transparent effects using RGBA, gradient effects, custom fonts, multi-background images, text or image deformation processing (rotation, scaling, tilting, moving), multi-column layout, media query, etc.
