定义

box-decoration-break属性是用来控制行内元素。

注意：可以控制行内元素包括：padding、background、border-image、border、margin和clip属性在行内元素多行情形下的渲染形式。

语法

box-decoration-break:slice|clone;

属性值

值	描述
clone	每个盒子的片段都有独立的border和padding。如果取值为clone，除了border和padding之外还有border-radius、border-image、box-shadow和background都会独立运用于元素的每个片段。
slice	取值为slice时，border和padding不会运用于元素被打断的片段中（除首行和末行），同时border-radius也只会运用于元素的四个顶角，对于打断片段之处并不会有任何的效果。而border-image和background会被运用于整个元素（全体是元素盒子是完整的）。
