如何在 bootstrap 5 col 内制作图像以跟随滚动但不低于 col 本身

How do I make image inside bootstrap 5 col to follow scroll but not below the col itself

在下面的代码中,“fixedContainer”中的图像位于 div 的顶部,但如果侧边栏有大量数据,它的高度就会很大,因此用户必须滚动。如何使图像跟随滚动但不低于 <div class="col-lg-8">

    <div class="container">
      <div class="row">
        <div class="col-lg-4">
                    <img src="https://img-prod-cms-rt-microsoft-com.akamaized.net/cms/api/am/imageFileData/RWMGbF?ver=ecec&q=90&m=6&h=201&w=358&b=%23FFFFFFFF&l=f&o=t&aim=true" height="600" width="50">                                                    
        </div>
        <div class="col-lg-8">
          <img src="https://img-prod-cms-rt-microsoft-com.akamaized.net/cms/api/am/imageFileData/RWMGbF?ver=ecec&q=90&m=6&h=201&w=358&b=%23FFFFFFFF&l=f&o=t&aim=true" alt="position-sticky" class="fixed">
        </div>
      </div>
        </div>

注意:我编辑了 post 并在左侧添加了一张设置了高高度的图片。但代码需要 运行 全屏才能看到问题,否则 col 会堆叠在一起。

对图像使用 position: stickytop: css

.fixed{
  position: sticky;
  top: 20px
}
