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">

分析:
bilibili 移动端vw / vh 手段制作案例_第2张图片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。
