The <clipPath>
SVG element defines a clipping path, to be used by the clip-path
property.
A clipping path restricts the region to which paint can be applied. Conceptually, parts of the drawing that lie outside of the region bounded by the clipping path are not drawn.
Usage context AttributesclipPathUnits
Defines the coordinate system for the contents of the <clipPath>
element. Value type: userSpaceOnUse
| objectBoundingBox
; Default value: userSpaceOnUse
; Animatable: yes
This element implements the SVGClipPathElement
interface.

A clipping path is conceptually equivalent to a custom viewport for the referencing element. Thus, it affects the rendering of an element, but not the element's inherent geometry. The bounding box of a clipped element (meaning, an element which references a <clipPath>
element via a clip-path
property, or a child of the referencing element) must remain the same as if it were not clipped.
By default, pointer-events
are not dispatched on clipped regions. For example, a circle with a radius of 10
which is clipped to a circle with a radius of 5
will not receive "click" events outside the smaller radius.
