1. 什么是Box Model

Box model is used to define how elements are rendered in a webpage. It consists four parts: content, padding, border, and margin.

• Content: 多为文本或图片, 尺寸用 width and height 定义

• Padding: content和border中间的部分, 尺寸用padding定义(一般定义padding时不用负数)

• Border: 环绕在padding和content外, 尺寸,样式和颜色用 border定义
