<shape>

The <shape> CSS data type defines the specific form (shape) of a region. The region represents the part of an element to which the <clip> property applies.

Note: <shape> and rect() work in conjunction with <clip>, which has been deprecated in favor of <clip-path>. When possible, use clip-path and the <basic-shape> data type instead.

Syntax

The <shape> data type is specified using the rect() function, which produces a region in the form of a rectangle.

rect()

rect(top, right, bottom, left)

Values

A graph showing top, right, bottom, and left, as described below. These define the rectangle's shape. The upper left corner is defined by the top and left values. The bottom right corner is defined by the bottom and right values.

top: Is a <length> representing the offset for the top of the rectangle relative to the top border of the element's box.
right: Is a <length> representing the offset for the right of the rectangle relative to the left border of the element's box.
bottom: Is a <length> representing the offset for the bottom of the rectangle relative to the top border of the element's box.
left: Is a <length> representing the offset for the left of the rectangle relative to the left border of the element's box.

Interpolation

When animated, values of the <shape> data type are interpolated over their top, right, bottom, and left components, each treated as a real, floating-point number. The speed of the interpolation is determined by the easing function associated with the animation.

Example

Example demonstrating correct use of the rect() function

img.clip04 {
  clip: rect(10px, 20px, 20px, 10px);
}
