柳树舒展开了黄绿嫩叶的枝条，在微微的春风中轻柔地拂动，就像一群群身着绿装的仙女在翩翩起舞。夹在柳树中间的桃树也开出了鲜艳的花朵，绿的柳，红的花，真是美极了！

最近研究CSS的时候发现了 仅使用两个CSS属性就可以制作出全屏滚动效果 ，这两个属性就是：

scroll-snap-type
scroll-snap-align

使用它就可以实现 fullpage.js 这种全屏滚动效果，其实，这种全屏滚动效果的理论非常简单，就是使用js监听界面滚动，当界面滚动到某个值时就让界面持续滚动到下一个屏幕，但是！要考虑到屏幕尺寸大小带来的兼容性问题就是一件非常麻烦的事情。

今天说的这两个属性并不能替代 fullpage.js ，有下面2个原因：

它们在浏览器上面存在兼容性问题。
CSS属性无法监听事件，也就无法提供动画完成时的回调函数。

1. 兼容性

目前主流的浏览器都已经支持了这两个CSS属性，可以放心的使用。如果你需要兼容IE浏览器，那么请选择 fullpage.js 。

2. 使用

使用的方法其实很简单， scroll-snap-type 属性放在 需要全屏滚动的容器的父容器上 ，而 scroll-snap-align 则需要 放在全屏滚动的容器上 ，多说无益，我们直接来看一下代码就可以很清楚的知道如何使用这两个CSS属性。

整个网页的完整代码很简单，下面直接将它贴上来：

<!DOCTYPE html>
<html lang="zh">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>CSS scroll snap</title>
    <style>
      body {
        margin: 0;
      }

      .container {
        height: 100vh;
        overflow-y: scroll;
        /* 在父容器上面使用 scroll-snap-type 属性 */
        scroll-snap-type: y mandatory;
      }

      section {
        padding: 112px;
        height: calc(100vh - 224px);
        color: white;
        /* 在需要滚动的容器上使用 scroll-snap-align 属性 */
        scroll-snap-align: start;
      }

      section:nth-of-type(1) {
        background-color: #60af15;
      }

      section:nth-of-type(2) {
        background-color: #158baf;
      }

      section:nth-of-type(3) {
        background-color: #af1581;
      }

      section h3 {
        font-size: 48px;
      }

      section p {
        font-size: 20px;
      }
    </style>
  </head>
  <body>
    <div class="container">

可以看到代码并不复杂，下面我们就着重讲解一下这两个CSS属性。
