经常在网上看见一下分割效果，或者模块标题效果：

代码结构：

<div class="fenge">
    <span>以上为精彩评论</span>
</div>
 
<style>
.fenge {
    text-align: center;
    position: relative;
    margin: 100px 20px;
}
 
.fenge:after {
    right: 0;
}
 
.fenge span {
    font-size: 12px;
    color: #99a2aa;
    line-height: 14px;
    vertical-align: top;
}
.fenge:after, .fenge:before {
    content: "";
    border-bottom: 1px solid #e8eaec;
    width: calc(50% - 50px);
    display: block;
    position: absolute;
    top: 7px;
}
</style>
