clip属性定义了元素的哪一部分是可见的。clip属性只适用于position:absolute的元素，即position:absolute或position:fixed...

/* Keyword value */
clip: auto;

/* <shape> values */
clip: rect(1px 10em 3rem 2ch);
clip: rect(1px, 10em, 3rem, 2ch);

/* Global values */
clip: inherit;
clip: initial;
clip: unset;

语法

警告：此属性不受欢迎。使用clip-path相反。

Initial value	auto
Applies to	absolutely positioned elements
Inherited	no
Media	visual
Computed value	auto if specified as auto, otherwise a rectangle with four values, each of which is auto if specified as auto or the computed length otherwise
Animation type	a rectangle
Canonical order	the unique non-ambiguous order defined by the formal grammar

值

<shape>一个矩形<shape>

rect(<top>, <right>, <bottom>, <left>)   /* 标准语法 */

或

rect(<top> <right> <bottom> <left>)      /* 向后兼容语法 */

<top>和<bottom>指定相对于盒子上边框边界的偏移，<right>和<left>指定了相对于盒子左边框边界的偏移。<top>，<right>，<bottom>，和<left>的值可以是<length>值或auto。

.如果任一边的值为auto，元素被裁剪到那边的内边缘一侧。auto元素默认不剪辑。请注意，这与rect(auto, auto, auto, auto)着实不同，rect会剪辑到元素的内部边框边缘。

形式语法

<shape> | autowhere 
<shape> = rect(<top>, <right>, <bottom>, <left>)

实例

.dotted-border { 
  border: dotted;  
  position: relative; 
  width: 536px;
  height: 350px;
}

#top-left, #middle, #bottom-right {
  position: absolute;
  top: 0px;
}

#top-left {
  left: 360px;
  clip: rect(0px, 175px, 113px, 0px); 
}


#middle {
  left: 280px;
  clip: rect(119px, 255px, 229px, 80px); 
  /* standard syntax, unsupported by Internet Explorer 4-7 */
}

#bottom-right {
  left: 200px;
  clip: rect(235px 335px 345px 160px);
  /* non-standard syntax, but supported by all major browsers*/
}
