## Description
|
||
<section id="description"> <code>box-shadow</code>属性将一个或多个阴影应用于元素。 <code>box-shadow</code>属性采用<code>offset-x</code>值（从元素水平推动阴影的距离）， <code>offset-y</code> （从元素垂直推动阴影的距离）， <code>blur-radius</code> ， <code>spread-radius</code>和颜色价值，按此顺序。 <code>blur-radius</code>和<code>spread-radius</code>值是可选的。这是一个用于创建具有一些模糊的多个阴影的CSS的示例，大多数是透明的黑色： <blockquote> box-shadow：0 10px 20px rgba（0,0,0,0.19），0 6px 6px rgba（0,0,0,0.23）; </blockquote></section>
