<p>当用户手动导航或者 CSSOM scrolling API 触发滚动操作时,<a href="/zh-CN/docs/Web/CSS">CSS</a> 属性 <strong><code>scroll-behavior</code></strong> 为一个滚动框指定滚动行为,其他任何的滚动,例如那些由于用户行为而产生的滚动,不受这个属性的影响。在根元素中指定这个属性时,它反而适用于视窗。</p>

<p>{{cssinfo}}</p>


<div>{{EmbedInteractiveExample("pages/css/scroll-behavior.html")}}</div>



<p>用户代理可以忽略此属性。</p>

 <dd>滚动框通过一个用户代理预定义的时长、使用预定义的时间函数,来实现平稳的滚动,用户代理应遵循其平台的约定,如果有的话。</dd>
