CSS Shapes - CSS: Cascading Style Sheets 编辑

CSS Shapes describe geometric shapes for use in CSS. For the Level 1 specification, CSS Shapes can be applied to floating elements. The specification defines a number of different ways to define a shape on a floated element, causing wrapping lines to wrap round the shape rather than following the rectangle of the element's box.

Basic example

The example below shows an image that has been floated left, and the shape-outside property applied with a value of circle(50%). This creates a circle shape, and the content wrapping the float now wraps around that shape. This changes the length of the wrapping text's line boxes.
