::before

css中“::before”的意思是“在…之前”，是一个伪类元素，用于创建一个伪元素，并将其设置为选中元素的第一个子元素，插入到元素的其他内容之前，语法为“element::before{样式代码}”。
transform

(变形) 支持旋转、扭曲、缩放、移动等
- 基点：所有操作的默认基点都在中心位置
- transform-origin：(x,y)改变元素基点。
a)rotate(xx deg)(2D), rotateX()(3D), rotateY()(3D) 旋转，正数为顺时针

b)translate(x,y) ，translateX(x) ，translateY(y)平移

c)scale(x,y)，scaleX(x,1)， scaleY(1,Y) 缩放基数为1，大于1放大，小于1缩小

d)skew(x,y)， skewX(x)， skewY(y) 扭曲
cursor: pointer;鼠标移动到元素上会有变化
:hover

在鼠标移到元素上时添加的特殊样式。
overflow-x指定是否要剪辑的左/右边缘的内容.

overflow-y指定是否要剪辑的顶部/底部边缘的内容
justify-content: space-between;

元素向两边对齐。注意，必须开启弹性盒子模型。
padding-inline-start: 0px;

去掉ul li开头前的空白。（会自带40px的空余）
overflow-y: auto;

设置y方向滚动轴，如果内容一处则滚动轴生效。(overflow)

注意：当父容器设定为百分比时，该属性会失效。必须设定父容器为固定宽高
