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.

The clip-path
property is specified as one or a combination of the values listed below.
Values
<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, theborder-box
will be used as the reference box. One of:inset()
-
Defines an inset rectangle.
circle()
-
Defines a circle using a radius and a position.
ellipse()
-
Defines an ellipse using two radii and a position.
polygon()
-
Defines a polygon using an SVG filling rule and a set of vertices.
path()
-
Defines a shape using an optional SVG filling rule and an SVG path definition.
<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 aborder-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 theviewBox
attribute and the dimension of the size of the reference box is set to the width and height values of theviewBox
attribute.
none
-
No clipping path is created.
Note: A computed value other than none
results in the creation of a new stacking context the same way that CSS opacity
does for values other than 1
.
Formal definition
Initial value | none |
---|---|
Applies to | all elements; In SVG, it applies to container elements excluding the <defs> element and all graphics elements |
Inherited | no |
Percentages | refer to reference box when specified, otherwise border-box |
Computed value | as specified, but with url() values made absolute |
Animation type | yes, as specified for <basic-shape> , otherwise no |
Formal syntax
