Question

我有一个包含袋子图像的页面，在我放置svg叠加层的袋子图像上方，问题是svg没有覆盖在图像上而且没有响应。

工作示例： https://jsbin.com/lilaxizizo/1/edit

代码：

<!DOCTYPE html>

<head>
    <title>SVG </title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

<svg style="position:absolute;z-index:10" height="300" width="500">

首先，如果您希望SVG具有响应能力，则需要为其指定viewBox。有关详细信息，请参阅此问题。

How can I make an svg scale with its parent container?

接下来，如果您希望SVG位于图像顶部，请使用<div>和postion: relative将它们包围起来。这样，如果你绝对定位SVG，它将相对于div而不是整个页面。

＆＃13;

div {
  position: relative;
}

img, svg {
  width: 500px;
}

svg {
  position: absolute;
  top: 0;
  left: 0;
}

＆＃13;

<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" />
   </svg>

</div>

Answer 2

将'margin-top'添加到svg元素。我测试了它，'-305px'的值似乎可以解决问题。

<svg style="margin-top:-305px;position:absolute;z-index:10" height="300" width="500">

Svg高于图像和比例
