overflow-clip-margin

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The overflow-clip-margin CSS property determines how far outside its bounds an element with overflow: clip may be painted before being clipped. The bound defined by this property is called the overflow clip edge of the box.

Syntax

css

/* <length> values */
overflow-clip-margin: 20px;
overflow-clip-margin: 1em;

/* <visual-box> | <length> */
overflow-clip-margin: content-box 5px;

/* Global values */
overflow-clip-margin: inherit;
overflow-clip-margin: initial;
overflow-clip-margin: revert;
overflow-clip-margin: revert-layer;
overflow-clip-margin: unset;

The <visual-box> value, which defaults to padding-box, specifies the box edge to use as the overflow clip edge origin. The <length> value specified in overflow-clip-margin must be nonnegative.

Note: If the element does not have overflow: clip then this property will be ignored.
