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

<a href="css/clip#shape"><shape></a> <a href="css/value_definition_syntax#single_bar" title="Single bar">|</a> auto<p>where <br><code><shape> = rect(<top>, <right>, <bottom>, <left>)</code></p>

Description  

The clip CSS property defines what portion of an element is visible. The clip property applies only to absolutely positioned elements, that is elements with position:absolute or position:fixed.
