如何css粘左引导4答案

【问题标题】：How to css sticky-left bootstrap 4如何css粘左引导4
【发布时间】：2019-07-07 10:52:12
【问题描述】：

我有一个带有侧面菜单的仪表板，我想将其固定在左侧。我尝试在 css 中做一个固定的位置，但是所有的 div 都被扭曲并移动到不合适的位置。然后我尝试使用引导程序sticky-left，但它根本不起作用。我希望在图表可滚动时左侧菜单保持固定。

代码：

<div class="row head">
      <div class="col-sm-2 sticky-left" id="side-bar">
          <div id="side-nav">
              <!--GREETING-->
          <div class="row greeting">
              <div class="col-sm-3" style="font-size: 2.6rem;">
                  <i class="far fa-user"></i>
              </div>

              <div class="col-sm-9">
                  <p>Hi Olivia!<br>School of UFeis</p>
              </div>
          </div>

          <!--LABEL-->

              </div>
          </div>
          <ul id="side-menu">

              <button>

希望您正在寻找sticky-top 侧边栏。

ul {
