這個 clip CSS 屬性用來定義元素的哪一個部分是可見的. clip 屬性只能被賦予在絕對位置的元素(element)上, 像是帶有這些的CSS屬性的元素 position:absolute (en-US) or position:fixed (en-US).

警告: 這個屬性被遺棄了. 請改用 clip-path (en-US) .

Applies toabsolutely positioned elements
Computed value (en-US)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 typea rectangle


/* 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;


A rectangular <shape> (en-US) of the form rect(<top>, <right>, <bottom>, <left>) or of the form rect(<top> <right> <bottom> <left>) (which is a more backwards compatible syntax) <top> and <bottom> specify offsets from the inside top border edge of the box, and <right>, and <left> specify offsets from the inside left border edge of the box — that is, the extent of the padding box.
<top>, <right>, <bottom>, and <left> may either have a <length> (en-US) value or auto. If any side's value is auto, the element is clipped to that side's inside border edge.
The element does not clip (default value). Note that this is distinct from rect(auto, auto, auto, auto), which does clip to the inside border edges of the element.

Formal syntax

<shape> | (en-US) auto

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


.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*/
<p class="dotted-border">
   <img src="" title="Original Graphic" />
   <img id="top-left" src="" title="Graphic clipped to upper left">
   <img id="middle" src="" title="Graphic clipped towards middle">
   <img id="bottom-right" src="" title="Graphic clipped to bottom right">
