本文介绍了如何将clipPath应用到div，其中clipPath位置相对于div位置的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
不知道我是否正确地制作了标题，但这里是问题。
我有一个类似云的形状的SVG路径，我想在CSS中使用 clip-path 属性。

其他类似的线程指出 clipPathUnits =objectBoundingBox属性应该添加到< clipPath> 对象，但这似乎不能解决我的问题。我甚至将路径从绝对路径转换为相对路径，并尝试它，但得到相同的结果。
有可能以剪裁路径与剪切元素链接
这是相对路径，如果它有帮助：

解决方案感谢 Robert的评论，我能够解决我有的问题。
这里是一个PHP代码段，用于将绝对路径转换为相对路径，以使值在0和1之间。

function regex_callback（$ matches）{
static $ count = -1;
$ count ++;
$ width = 98;
$ height = 70;
if（$ count％2）{
return $ matches [0] / $ height;
} else {
return $ matches [0] / $ width;
}
}
$ relative_path = preg_replace_callback（'（\d +（\.\d +）？）'，'regex_callback'，$ absolute_path）;
由于剪切路径不是矩形，我不能用一个数字分割值，要使用剪切路径本身的宽度和高度。

Not sure if I've formulated the title properly, but here goes the question.
I have an SVG path of a cloud-like shape which I would like to use in CSS with the clip-path property.
<path d="M46.9819755,61.8637972 C42.0075109,66.8848566 35.0759468,70 27.4091794,70 C12.2715076,70 0,57.8557238 0,42.875 C0,32.9452436 5.3914988,24.2616832 13.4354963,19.534921 C14.8172134,8.52285244 24.3072531,0 35.8087666,0 C43.9305035,0 51.0492374,4.2498423 55.01819,10.6250065 C58.2376107,8.87215568 61.9363599,7.875 65.8704472,7.875 C78.322403,7.875 88.4167076,17.8646465 88.4167076,30.1875 C88.4167076,32.1602271 88.1580127,34.0731592 87.6723639,35.8948845 L87.6723639,35.8948845 C93.3534903,38.685457 97.2583784,44.4851888 97.2583784,51.1875 C97.2583784,60.6108585 89.5392042,68.25 80.0171204,68.25 C75.4841931,68.25 71.3598367,66.5188366 68.2822969,63.6881381 C65.5613034,65.4654463 62.3012892,66.5 58.7971106,66.5 C54.2246352,66.5 50.0678912,64.7384974 46.9819755,61.8637972 Z" fill="lightblue" />
When I add an SVG element in HTML and define <clipPath> with that path, the browser positions the clipping path in the top-left corner. If I apply a margin to the clipped element, the mask is not linked and stays in its initial position.
Other similar threads state that the clipPathUnits="objectBoundingBox" attribute should be added to the <clipPath> object, but that doesn't seem to solve my problem. I even transformed the path from absolute to relative and tried it like that, but got the same result.
Is it possible to somehow link the clipping path with the clipped element so that when positioning is applied to the clipped element, the clipping path moves as well?
Here is the relative path, if it helps:
<path d="M46.9819755,61.8637972c-4.974,5.021,-11.906,8.136,-19.573,8.136c-15.137,0,-27.409,-12.144,-27.409,-27.125c0,-9.93,5.392,-18.613,13.436,-23.34c1.381,-11.012,10.871,-19.535,22.373,-19.535c8.122,0,15.24,4.25,19.209,10.625c3.22,-1.753,6.918,-2.75,10.852,-2.75c12.452,0,22.547,9.99,22.547,22.313c0,1.972,-0.259,3.885,-0.745,5.707l0,0c5.682,2.791,9.586,8.59,9.586,15.293c0,9.423,-7.719,17.062,-17.241,17.062c-4.533,0,-8.657,-1.731,-11.735,-4.562c-2.721,1.778,-5.981,2.812,-9.485,2.812c-4.572,0,-8.729,-1.761,-11.815,-4.636z fill="lightblue" />
As well as some test HTML/CSS. (I've set the left property to 10px so that you see the clipping issue occur)

解决方案 Thanks to Robert's comment, I was able to solve the issue I had.
Here is a PHP snippet I used to convert the absolute path to relative, so that the values are between 0 and 1.
$absolute_path = "M46.9819755,61.8637972 C42.0075109,66.8848566 35.0759468,70 27.4091794,70 C12.2715076,70 0,57.8557238 0,42.875 C0,32.9452436 5.3914988,24.2616832 13.4354963,19.534921 C14.8172134,8.52285244 24.3072531,0 35.8087666,0 C43.9305035,0 51.0492374,4.2498423 55.01819,10.6250065 C58.2376107,8.87215568 61.9363599,7.875 65.8704472,7.875 C78.322403,7.875 88.4167076,17.8646465 88.4167076,30.1875 C88.4167076,32.1602271 88.1580127,34.0731592 87.6723639,35.8948845 L87.6723639,35.8948845 C93.3534903,38.685457 97.2583784,44.4851888 97.2583784,51.1875 C97.2583784,60.6108585 89.5392042,68.25 80.0171204,68.25 C75.4841931,68.25 71.3598367,66.5188366 68.2822969,63.6881381 C65.5613034,65.4654463 62.3012892,66.5 58.7971106,66.5 C54.2246352,66.5 50.0678912,64.7384974 46.9819755,61.8637972 Z";
function regex_callback($matches) {
static $count = -1;
$count++;
$width = 98;
$height = 70;
if($count % 2) {
return $matches[0] / $height;
} else {
return $matches[0] / $width;
}
}
$relative_path = preg_replace_callback('(\d+(\.\d+)?)', 'regex_callback', $absolute_path);
Since the clipping path is not rectangular, I couldn't divide the values with one number, but had to use the width and the height of the clipping path itself.
