CSS flex如何均匀排列子元素

高级justify-content: space-between;法

直接使用list的before和after伪元素参与布局

  <ul class="share-list">
      <li class="share-item"></li>
      <li class="share-item"></li>
      <li class="share-item"></li>
  </ul>

.share-list{
    display: flex;
    justify-content: space-between;
}
.share-list:before,
.share-list:after{
    content: "";
}
.share-item{
    width: 60px;
    height: 60px;
}
