我有一个页面,其中有一个包的图像,在包图像上方我放置了一个 svg 覆盖层,问题是 svg 没有重叠在图像上,也没有响应。
工作示例: https://jsbin.com/lilaxizizo/1/edit
代码:
<!DOCTYPE html>
<html>
<head>
<title>SVG </title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

Sorry, your browser does not support inline SVG.

最佳答案
首先,如果您希望 SVG 具有响应能力,您需要给它一个 viewBox
。请参阅此问题了解更多详细信息。

接下来,如果您希望 SVG 位于图像顶部,请用 <div>
将它们包围起来。与 postion: relative
。这样,如果您对 SVG 进行绝对定位,它将相对于 div 而不是整个页面。
div {
position: relative;
}
img, svg {
width: 500px;
}
svg {
position: absolute;
top: 0;
left: 0;
}
<div>
<img class="img-responsive" src="http://i.imgur.com/icQzdFl.jpg">
<svg height="300" width="500">
<polygon points="103,79,119,74,136,68,173,67,202,70,262,78,316,89,380,97,393,121,402,157,407,184,418,216,424,249,419,261,404,274,359,288,332,294,271,284,195,266,142,255,83,238,59,223,64,177" style="fill-opacity:0.1;fill:lime;stroke:purple;stroke-width:1" />
