clip-path属性指定为下面列出的值的一个或多个值的组合.
<clip-source><geometry-box><basic-shape> 一起声明,它将为基本形状提供相应的参考框盒。通过自定义,它将利用确定的盒子边缘包括任何形状边角(比如说,被 {{cssxref("border-radius")}} 定义的剪切路径)。几何框盒可以有以下的值中的一个:margin-boxborder-boxpadding-boxcontent-boxfill-boxstroke-boxview-boxviewBox 属性建立的坐标系的原点,引用框的尺寸用来设置 viewBox 属性的宽高值。noneNote: A computed value other than none results in the creation of a new stacking context the same way that CSS {{cssxref("opacity")}} does for values other than 1.
