用css绘制不规则形状（应该有响应）

有没有办法用css绘制形状（下图）？灰色边框样式应为虚线。 最重要的是响应（应该调整不同尺寸的半径的屏幕）。

错误的例子（没有回复）：

＆＃13;
＆＃13; 
#box {
    position: relative;
    margin: 30px;
    width: 200px;
    height: 100px;
    background: #fff;
    border: 1px dashed #333;
}

.corner {
    position: absolute;
    height: 10px;
    width: 10px;
    border: 1px dashed #333;
    background-color: #fff;
}

.top-left {
    top: -1px;
    left: -1px;
    border-radius: 0 0 100% 0;
    border-width: 0 1px 1px 0;
}
＆＃13; 
<div id="box">
    <div class="corner top-left"></div>
</div>
＆＃13;
＆＃13;
＆＃13;

我的建议是与SVG一起使用。这是它的用途。这是一个例子...... 

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="100%" viewBox="0 0 256 128" enable-background="new 0 0 256 128" xml:space="preserve">
    <path fill="#FFFFFF" stroke="#828282" stroke-dasharray="10" stroke-width="5" d="M249.75,121h-242V64c0,0,56.5,4.75,56.5-56.5h185.5V121z" />
</svg>

我回答一下，因为我的评论似乎给你带来了一些想法。

这个想法基于（codepen）

p {
  margin: 0;
  text-shadow: 0 0 1px;
  text-align:justify;
}

div {
  font-size:2em;
  width: 80%;
  background: white;
  margin: 10% 2em 2em 10%;
  padding: 15px;
  border: 15px dashed gray;
  position: relative;
  mix-blend-mode: multiply;
}

div:before {
  padding: calc(3% + 10px);
  float: left;
  content: '';
}

div:after {
  position: absolute;
  content: '';
  padding: 7%;
  border: inherit;
  border-radius: 50%;
  top: 0;
  left: 0;
  margin: calc(-10% - 7px);
  box-shadow: 0 0 0 15px white, inset 0 0 0 150px white;
}

div + div:after {
  background: url(http://lorempixel.com/250/250/people/6) center ;
  box-shadow: 0 0 0 15px white;
}

p:before {
  content: '';
  border-radius: 50%;
  padding: calc(7% + 35px);
  position: absolute;
  background: repeating-linear-gradient(45deg, transparent 0, transparent 20px, gray 20px, gray 45px) bottom right no-repeat ;
  background-size: 35% 39.5%;
  top: -20px;;
  left: -20px;
  margin: -10%
}

body {
  background: url(http://lorempixel.com/640/480/nature/6) yellow;
  background-size: cover
}
