我有一个使用SVG clipPath剪裁的图像。但是,我希望图像水平居中对齐。在clipPath中垂直。

有办法做到这一点吗?

您的剪辑路径使用绝对坐标,因此它基本上固定在页面上。 您可以设置img尺寸以匹配箭头形状的大小(约258x156)。但这会使图像变形。

或者你可以通过仅将图像的宽度设置为258来保持图像的纵横比正确。然后使用相对定位将其中心移动一点......

body, svg {
  margin: 0;
  padding: 0;
}

img {
  clip-path: url(#svgPath2);
  -webkit-clip-path: url(#svgPath2);
  position: relative;
  top: -20px;
}

或者更简单的方法是将包含div设置为箭头形状的大小并将剪辑应用于该形状。使用background-szie: cover将图像居中。

body, svg {
  margin: 0;
  padding: 0;
}

.arrow-cards {
  width: 265px;
  height: 165px;
  background-image: url(http://static2.businessinsider.com/image/4f3433986bb3f7b67a00003c/a-parasite-found-in-cats-could-be-manipulating-our-brains.jpg);
  background-size: cover;
  clip-path: url(#svgPath2);
  -webkit-clip-path: url(#svgPath2);
}
&#13;
<div class="arrow-cards"></div>

如果您打算在页面的不同位置设置箭头形状,您可能希望查看使用clipPathUnits="objectBoundingBox"定义剪辑路径。这样,它可以应用于页面上任何位置的元素,并将进行调整以适合元素形状。
