CSS常用样式之绘制双箭头的示例代码
导读
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:
双三角覆盖这种方式也能直接绘制双箭头,但是实现比较麻烦,不如边框旋转方式好实现就不讲了
