在MDN上有一个示例,说明如何在图像上使用剪切路径svg。相同的剪切路径似乎不适用于div
元素。有人可以澄清一下吗?
裁剪图像的示例代码(based on MDN docs)
#clipped {
clip-path: url(#cross);
}
<img id="clipped" src="https://mdn.mozillademos.org/files/12668/MDN.svg"
alt="MDN logo">
<svg height="0" width="0">
<defs>
<clipPath id="cross">
<rect y="110" x="137" width="90" height="90"/>
<rect x="0" y="110" width="90" height="90"/>
<rect x="137" y="0" width="90" height="90"/>
<rect x="0" y="0" width="90" height="90"/>
</clipPath>
</defs>
</svg>
div上的相同剪切路径(似乎不起作用)
#clipped {
width: 100px;
height: 100px;
background: black;
clip-path: url(#cross);
}
<div id="clipped"></div>
<svg height="0" width="0">
<defs>
<clipPath id="cross">
<rect y="110" x="137" width="90" height="90"/>
<rect x="0" y="110" width="90" height="90"/>
<rect x="137" y="0" width="90" height="90"/>
<rect x="0" y="0" width="90" height="90"/>
</clipPath>
</defs>
</svg>

正如@enxaneta指出的,这全都取决于大小。如果增加div的大小,则会看到效果:
#clipped {
width: 300px;
height: 200px;
background: black;
clip-path: url(#cross);
}
<div id="clipped"></div>
<svg height="0" width="0">
<defs>
<clipPath id="cross">
<rect y="110" x="137" width="90" height="90"/>
<rect x="0" y="110" width="90" height="90"/>
<rect x="137" y="0" width="90" height="90"/>
<rect x="0" y="0" width="90" height="90"/>
</clipPath>
</defs>
</svg>
或者您可以使用mask
来使动态变化。每个角上都有4个白色矩形和白色的技巧是使其可见
.box {
width: 100px;
height: 100px;
margin:5px;
background: linear-gradient(red,blue);
-webkit-mask:
linear-gradient(white,white) top left,
linear-gradient(white,white) top right,
linear-gradient(white,white) bottom left,
linear-gradient(white,white) bottom right;
-webkit-mask-size:40% 40%;
-webkit-mask-repeat:no-repeat;
-mask:
linear-gradient(white,white) top left,
linear-gradient(white,white) top right,
linear-gradient(white,white) bottom left,
linear-gradient(white,white) bottom right;
mask-size:40% 40%;
mask-repeat:no-repeat;
}
<div class="box"></div>
<div class="box" style="width:200px;height:200px;"></div>

您的问题的一种解决方案是使用clipPathUnits="objectBoundingBox"
并构建大小在0到1之间的剪切路径,如下所示:
#clipped {
margin:1em;
width: 100px;
height: 100px;
background: black;
display:inline-block;
clip-path: url(#cross);
}
#clipped.big{
width: 200px;
height: 200px;
}
<div id="clipped"></div>
<div id="clipped" class="big"></div>
<svg viewBox="0 0 1 1">
<clipPath id="cross" clipPathUnits="objectBoundingBox">
<rect y="0" x="0" width=".4" height=".4"/>
<rect y="0.6" x="0" width=".4" height=".4"/>
<rect y="0" x="0.6" width=".4" height=".4"/>
<rect y="0.6" x="0.6" width=".4" height=".4"/>
</clipPath>
</svg>

Clip-path
不被继承。 Establishing a new clipping path: the ‘clipPath’ element W3C
因此,我们不会通过将clip-path
应用于父块来削减子元素
最好使用svg <image>
标记代替<img>
并对其应用clip-path
使用div作为自适应容器
.wrapped {
width:25%;
height:25%;
}
#img1 {
clip-path:url(#cross);
}
<div class="wrapped">
<svg viewBox="0 0 250 250">
<defs>
<clipPath id="cross">
<rect y="110" x="137" width="90" height="90"/>
<rect x="0" y="110" width="90" height="90"/>
<rect x="137" y="0" width="90" height="90"/>
<rect x="0" y="0" width="90" height="90"/>
</clipPath>
</defs>
<image id="img1" width="100%" height="100%" xlink:href="https://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg"/>
</svg>
</div>
