带边框的响应式六边形网格

Question

http://codepen.io/web-tiki/pen/HhCyd

我正在使用来自类似问题的上述笔。我能够编辑六边形的大小，编辑宽度属性和填充，但我想为六边形添加一个边框，我可以通过添加一个边框和编辑框的大小来在六边形的左侧和右侧category li div 元素，但无法通过编辑 category li 元素获取六边形的另一边。

这对我来说效果很好，希望对你也有帮助。

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

.hexagon {
  position: relative;
  width: 300px; 
  height: 173.21px;
  background-color: #64C7CC;
  margin: 86.60px 0;
  border-left: solid 5px #333333;
  border-right: solid 5px #333333;
}

.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: 38.9340px;
}

.hexagon:before {
  top: -106.0660px;
  border-top: solid 7.0711px #333333;
  border-right: solid 7.0711px #333333;
}

.hexagon:after {
  bottom: -106.0660px;
  border-bottom: solid 7.0711px #333333;
  border-left: solid 7.0711px #333333;
}

对于六边形内的图像，请使用：

<div class="hexagon">
  <div class="hexTop"></div>
  <div class="hexBottom"></div>
</div>

.hexagon {
  position: relative;
  width: 300px; 
  height: 173.21px;
  margin: 86.60px 0;
  background-image: url(http://you_image_url.jpg);
  background-size: auto 334.8632px;
  background-position: center;
  border-left: solid 5px #333333;
  border-right: solid 5px #333333;
}

.hexTop,
.hexBottom {
  position: absolute;
  z-index: 1;
  width: 212.13px;
  height: 212.13px;
  overflow: hidden;
  -webkit-transform: scaleY(0.5774) rotate(-45deg);
  -ms-transform: scaleY(0.5774) rotate(-45deg);
  transform: scaleY(0.5774) rotate(-45deg);
  background: inherit;
  left: 38.93px;
}

/*counter transform the bg image on the caps*/

.hexTop {

  border-top: solid 7.0711px #333333;
  border-right: solid 7.0711px #333333;
