clip-path
CSS 属性使用裁剪方式创建元素的可显示区域。区域内的部分显示,区域外的隐藏。

/* Keyword values */ clip-path: none; /* <clip-source> values */ clip-path: url(resources.svg#c1); /* <geometry-box> values */ clip-path: margin-box; clip-path: border-box; clip-path: padding-box; clip-path: content-box; clip-path: fill-box; clip-path: stroke-box; clip-path: view-box; /* <basic-shape> values */ clip-path: inset(100px 50px); clip-path: circle(50px at 0 100px); clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%); clip-path: path('M0.5,1 C0.5,1,0,0.7,0,0.3 A0.25,0.25,1,1,1,0.5,0.3 A0.25,0.25,1,1,1,1,0.3 C1,0.7,0.5,1,0.5,1 Z'); /* Box and shape values combined */ clip-path: padding-box circle(50px at 0 100px); /* Global values */ clip-path: inherit; clip-path: initial; clip-path: unset;
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-box
border-box
padding-box
content-box
fill-box
stroke-box
view-box
viewBox
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。none
Note: 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
