/*为保证通用性 尽量多添加父级div来帮助指定内容的大小和位置*/
/*min-height 指定容器默认高度*/
/*CSS书写顺序*/
/*1.位置属性(position, top, right, z-index,display, float等)*/
/*另，布局排版优先采用display: flex;*/
/*2.大小(width, height, padding, margin)*/
/*3.文字系列(font, line-height, letter-spacing, color- text-align等)*/
/*4.背景(background, border等)*/
/*5.其他(animation, transition等)*/
