<shape> - CSS: Cascading Style Sheets 编辑

Deprecated

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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

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 timing function associated with the animation.

Example

Example demonstrating correct use of the rect() function

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