Cascading Style Sheets (Cascading Style Sheets) is a computer language used to express HTML (an application of Standard Universal Markup Language) or XML (a subset of Standard Universal Markup Language). The latest version of CSS is CSS3, which is a style design language that can truly separate web page performance and content. Compared with the performance of traditional HTML, CSS can accurately control the position and layout of objects in web pages, supports almost all font size styles, has the ability to edit web page objects and model styles, and can perform preliminary interactions. Design is currently the best expressive design language based on text display.
