html - 带虚线边框的CSS3六 Angular 形

我可以实现带有实心边框的六边形，如下所示:

.hex {
  margin-top: 70px;
  width: 208px;
  height: 120px;
  background: red;
  position: relative;
}
.hex:before,
.hex:after {
  content: "";
  border-left: 104px solid transparent;
  border-right: 104px solid transparent;
  position: absolute;
}
.hex:before {
  top: -59px;
  border-bottom: 60px solid red;
}
.hex:after {
  bottom: -59px;
  border-top: 60px solid red;
}
.hex.inner {
  background-color: lightgreen;
  -webkit-transform: scale(.98, .98);
  -moz-transform: scale(.98, .98);
  transform: scale(.98, .98);
  z-index: 1;
}
.hex.inner:before {
  border-bottom: 60px solid lightgreen;
}
.hex.inner:after {
  border-top: 60px solid lightgreen;
}

<div class="hex">
  <div class="hex inner">
  </div>
</div>

但是，我想创建一个带有虚线边框的六边形，如下图所示:

最佳答案

HTML程式码:

<div class="hexagon"><span></span></div>

CSS代码:

  .hexagon {
  position: relative;
  width: 300px;
  height: 173.21px;
  background-color: lightgreen;
  margin: 86.60px 0;
   border-left: 3px dotted #f00;;
  border-right:3px dotted #f00;
  box-shadow: 0 0 20px rgba(0,0,0,0.6);
}

.hexagon:before,
.hexagon:after {
  content: "";
  position: absolute;
  z-index: 1;
  width: 212.13px;
  height: 212.13px;
  -webkit-transform: scaleY(0.5774) rotate(-45deg);
  -ms-transform: scaleY(0.5774) rotate(-45deg);
  transform: scaleY(0.5774) rotate(-45deg);
  background-color: inherit;
  left: 40.9340px;
  box-shadow: 0 0 20px rgba(0,0,0,0.6);
}

.hexagon:before {
  top: -106.0660px;
  border-top: 3px dotted #f00;
  border-right:3px dotted #f00;
}

.hexagon:after {
  bottom: -106.0660px;
  border-bottom: 3px dotted #f00;
  border-left: 3px dotted #f00;
}

/*cover up extra shadows*/
.hexagon span {
  display: block;
  position: absolute;
  top:1.7320508075688772px;
  left: 0;
  width:294px;
  height:169.7410px;
  z-index: 2;
  background: inherit;
}

输出 :



根据需要应用颜色。
