css is Cascading Style Sheets (English full name: Cascading Style Sheets), a computer language used to express file styles such as HTML (an application of Standard Generalized Markup Language) or XML (a subset of Standard Generalized Markup Language). . CSS can not only statically modify web pages, but can also cooperate with various scripting languages to dynamically format various elements of web pages. CSS can perform pixel-level precise control over the layout of element positions in web pages, supports almost all font size styles, and has the ability to edit web page object and model styles.

Here are a few small cases to teach you how to draw some graphics with css:
