Syntax

/* 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;

Values

<shape>
A rectangular <shape> 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> value or auto. If any side's value is auto, the element is clipped to that side's inside border edge.
auto
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> | auto

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

Examples

.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*/
}
