添加 '边距' 到SVG元素。我已经测试过它,并且'-305px'的值似乎有诀窍。

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

没有响应,尝试调整它,你给的解决方案是非常错误的,如果继续调整窗口大小,是不是稳定 – Pedro

我做了谷歌搜索只是在“缩放一个SVG',并且有无数的资源(大部分已经在stackoverflow上)都提到了viewBox。当你真正陷入困境时,Stackoverflow可以提供帮助。请在未来研究。 –

首先,如果你想要SVG响应,你需要给它一个viewBox。看到这个问题的更多细节。

接下来,如果您希望SVG坐在图像的顶部,包围他们都与一个postion: relative<div>。这样,如果你绝对SVG的位置,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" /> 
 
    </svg> 
 

 
</div>

这是固定大小;不响应。 – frezq
