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

Syntax

/* 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: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);

/* 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.

Values

<clip-source>
A <url> referencing a clipping path 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.

Formal syntax

<clip-source> | [ <basic-shape> || <geometry-box> ] | none
where 
<clip-source> = <url>
<basic-shape> = <inset()> | <circle()> | <ellipse()> | <polygon()>
<geometry-box> = <shape-box> | fill-box | stroke-box | view-box
where 
<inset()> = inset( <length-percentage>{1,4} [ round <border-radius> ]? )
<circle()> = circle( [ <shape-radius> ]? [ at <position> ]? )
<ellipse()> = ellipse( [ <shape-radius>{2} ]? [ at <position> ]? )
<polygon()> = polygon( <fill-rule>? , [ <length-percentage> <length-percentage> ]# )
<shape-box> = <box> | margin-box
where 
<length-percentage> = <length> | <percentage>
<shape-radius> = <length-percentage> | closest-side | farthest-side
<position> = [ [ left | center | right ] || [ top | center | bottom ] | [ left | center | right | <length-percentage> ] [ top | center | bottom | <length-percentage> ]? | [ [ left | right ] <length-percentage> ] && [ [ top | bottom ] <length-percentage> ] ]
<fill-rule> = nonzero | evenodd
<box> = border-box | padding-box | content-box

1. Edge only supports clip paths defined by url().

2. Internet Explorer only supports clip paths defined by url().

3. From version 47: this feature is behind the layout.css.clip-path-shapes.enabled preference (needs to be set to true). To change preferences in Firefox, visit about:config.

4. This value was supported before Firefox 51, but as an alias to border-box.
