使用一行CSS代码来实现网页全屏效果

原文提到了很多种方式来实现全屏，在这里仅仅摘出使用一行CSS代码实现的方法，非常简便快捷。

关键在于

.section { height: 100vh; }

vh就是viewport height的缩写，1vh等于浏览器高度的1%。vh可以毫不费力地获取任何时刻你的浏览器的当前高度，从而对你的section进行相应设置。

下面是一个DEMO。

HTML代码：

  
  

    
You can create full screen sections without javascript.
    
The height is set to 90vh, that means 90% height.
 


  
  

    
Resize your browser and see how they adapt.
 


  
  

    
It's amazing and fast.
