一、多次调用单箭头

实现了单箭头–就很容易实现双箭头了，上文已经介绍2种实现单箭头的原理：边框旋转方式、双三角覆盖方式。这次以边框旋转为例多次调用实现双箭头。
1、边框旋转单箭头实现

.arrow-right{
  height: 120px;
  width: 30px;
  display :inline-block;
  position: relative;
}
.arrow-right::after {
  content: "";
  height: 60px;
  width: 60px;
  top: 12px;
  border-width: 8px 8px 0 0;
  border-color: blue;
  border-style: solid;
  transform: matrix(0.71, 0.71, -0.71, 0.71, 0, 0);
  position: absolute;
}

效果图如下：

2、多次调用单箭头

<div>
	<span class="arrow-right"/>
    <span class="arrow-right"/>
</div>

效果图如下：

二、旋转边框直接绘制双箭头

之前通过::after伪元素绘制单箭头，现在再加上::before伪元素再绘制一个单箭头就实现纯CSS绘制双箭头了。

.arrow-right{
  height: 120px;
  width: 30px;
  display :inline-block;
  position: relative;
}
.arrow-right::before {
  content: "";
  height: 60px;
  width: 60px;
  top: 12px;
  left: 30px;
  border-width: 8px 8px 0 0;
  border-color: blue;
  border-style: solid;
  transform: matrix(0.71, 0.71, -0.71, 0.71, 0, 0);
  position: absolute;
}
.arrow-right::after {
  content: "";
  height: 60px;
  width: 60px;
  top: 12px;
  border-width: 8px 8px 0 0;
  border-color: blue;
  border-style: solid;
  transform: matrix(0.71, 0.71, -0.71, 0.71, 0, 0);
  position: absolute;
}

效果图如下：
