我想在div的左侧和右侧有一个箭头.像这里,但双方：

那可能吗？
解决方法
在.arrow中添加一个额外的div,在其上添加：before和：after伪类. (注意：由于额外的边框,额外的div是必要的.边框是通过创建两个重叠的div来创建的：before和：after)
.arrow_Box { position: relative; background: #88b7d5; border: 4px solid #c2e1f5; width: 200px; } .arrow_Box:after,.arrow_Box:before { bottom: 100%; border: solid transparent; content: " "; height: 0; width: 0; position: absolute; } .arrow_Box:after { border-color: rgba(136,183,213,0); border-bottom-color: #88b7d5; border-width: 30px; left: 50%; margin-left: -30px; } .arrow_Box:before { border-color: rgba(194,225,245,0); border-bottom-color: #c2e1f5; border-width: 36px; left: 50%; margin-left: -36px; } .arrow_Box > div:after,.arrow_Box > div:before { top: 100%; border: solid transparent; content: ""; height: 0; width: 0; position: absolute; } .arrow_Box > div:after { border-color: rgba(136,0); border-top-color: #88b7d5; border-width: 30px; left: 50%; margin-left: -30px; } .arrow_Box > div:before { border-color: rgba(194,0); border-top-color: #c2e1f5; border-width: 36px; left: 50%; margin-left: -36px; }
<div class="arrow_Box"> <div> bla!<br /> bla!<br /> bla!<br /> bla!<br /> bla!<br /> bla!<br /> </div> </div>
