bilibili 移动端vw / vh 手段制作案例
现在比较流行的是rem制作方法，但是现在大厂（b站等）已经开始尝试使用vw、vh技术了，所以要学习vw技术，vw技术的优点就在于不用引入js文件等，相对于rem比较简单，使用过程可以全部使用vw或者全部使用vh作为单位，不建议vw和vh混合使用模式。
单纯将字体图标和.css文件引入就可以了
<link rel="stylesheet" href="./fonts/iconfont.css">
<link rel="stylesheet" href="./css/index.css">
整体制作效果
分析：
这一部分是作为头部进行展示，这一部分要是用固定定位的效果进行压盖在最上面，大盒子又分为上下两个盒子，上面的盒子又分为左右两边，使用主轴两边贴的方式就可以了。
这一部分是盒子的视频展示区 整体有一个大盒子作为视频区，这个还得要注意使用换行处理，否则使用弹性布局的话就会使得8个盒子挤到一行显示。
