如何使用纯 CSS 创建带有虚线的票据形状?

Sam*_*mmi 2 html css border css-shapes box-shadow

我想用纯CSS创建一个票据形状(4个角用圆圈裁剪),但是当我尝试为其添加边框时遇到了一些困难。我尝试过处理 box-shadow 但失败了。我正在尝试用两种样式制作它 - 1.我可以为整个形状(包括圆角)设置 3px 边框 2.我可以为整个形状设置 3px 边框,但采用虚线样式

由于我对box-shadow不太熟悉,很难实现我想要的风格。有人能给我一些提示吗?太感谢了。

这是一个想法,您还可以在伪元素上使用点线边框,同时隐藏主元素的一些边框:

.ticket {
  font-size: 20px;
  position: relative;
  background: #4a4a4a;
  float: left;
  padding: 35px 30px;
  margin:20px;
  border:4px dotted #fff;
}

.ticket:after,
.ticket:before,
.ticket a:after,
.ticket a:before {
    content: "";
    position: absolute;
    z-index: 1;
    width: 15px;
    height: 15px;
    background: 
      linear-gradient(#fff,#fff) padding-box,
      #4a4a4a;
}
.ticket:after {
  top: -5px;
  left: -5px;
  border-right: #fff 5px dotted;
  border-bottom: #fff 5px dotted;
  border-radius: 0 0 20px 0;
}

.ticket:before {
  top: -5px;
  right: -5px;
  border-left: #fff 5px dotted;
  border-bottom: #fff 5px dotted;
  border-radius: 0 0 0 20px;
}

.ticket a {
  padding: 35px;
  text-decoration: none;
  color: #fff;
}

.ticket a:after {
  bottom: -5px;
  left: -5px;
  border-right: #fff 5px dotted;
  border-top: #fff 5px dotted;
  border-radius: 0 20px 0 0;
}

.ticket a:before {
  bottom: -5px;
  right: -5px;
  border-left: #fff 5px dotted;
  border-top: #fff 5px dotted;
  border-radius: 20px 0 0 0;
