clip-path

The clip-path CSS property creates a clipping region that sets what part of an element should be shown. Parts that are inside the region are shown, while those outside are hidden.

/* Keyword values */
clip-path: none;

/* <clip-source> values */
clip-path: url(resources.svg#c1);

/* <geometry-box> values */
clip-path: margin-box;
clip-path: border-box;
clip-path: padding-box;
clip-path: content-box;
clip-path: fill-box;
clip-path: stroke-box;
clip-path: view-box;

/* <basic-shape> values */
clip-path: inset(100px 50px);
clip-path: circle(50px at 0 100px);
clip-path: ellipse(50px 60px at 0 10% 20%);
clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
clip-path: path('M0.5,1 C0.5,1,0,0.7,0,0.3 A0.25,0.25,1,1,1,0.5,0.3 A0.25,0.25,1,1,1,1,0.3 C1,0.7,0.5,1,0.5,1 Z');

/* Box and shape values combined */
clip-path: padding-box circle(50px at 0 100px);

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

The clip-path property is specified as one or a combination of the values listed below.

<clip-source>

A <url>() referencing an SVG <clipPath> element.

<basic-shape>

A shape whose size and position is defined by the <geometry-box> value. If no geometry box is specified, the border-box will be used as the reference box.

<geometry-box>

If specified in combination with a <basic-shape>, this value defines the reference box for the basic shape. If specified by itself, it causes the edges of the specified box, including any corner shaping (such as a border-radius), to be the clipping path. The geometry box can be one of the following values:

margin-box

Uses the margin box as the reference box.

border-box

Uses the border box as the reference box.

padding-box

Uses the padding box as the reference box.

content-box

Uses the content box as the reference box.

fill-box

Uses the object bounding box as the reference box.

stroke-box

Uses the stroke bounding box as the reference box.

view-box

Uses the nearest SVG viewport as the reference box. If a viewBox attribute is specified for the element creating the SVG viewport, the reference box is positioned at the origin of the coordinate system established by the viewBox attribute and the dimension of the size of the reference box is set to the width and height values of the viewBox attribute.

none

No clipping path is created.
