html - bootstrap 4 中的重叠列

Question

我有一行，里面有三列，如下所示:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">

<section>
  <div class="container">
    <div class="row">
      <div class="col-4">
        <img class="img-fluid" src="https://via.placeholder.com/321x620" alt="" />
      </div>
      <div class="col-4">
        <img class="img-fluid" src="https://via.placeholder.com/321x620" alt="" />
      </div>
      <div class="col-4">
        <img class="img-fluid" src="https://via.placeholder.com/321x620" alt="" />
      </div>
    </div>
  </div>
</section>

我希望这三列重叠并产生如下幻觉:

每个瓶子代表我在上面的代码片段中拥有的每个图像。

感谢您的帮助

注意 中间的图片应该看起来在前面并且比后面的其他两个图片大(完全如图所示)

Answer 1

如果你想一直重叠，而不是使用网格，你可以使用负边距:

.bottle {
  width: 100px;
  height: auto;
  border: 1px solid black;
}

.bottles .bottle:first-child {
  margin-right: -30px;
}

.bottles .bottle:last-child {
  position: relative;
  margin-left: -30px;
  z-index: -1;
}

<div class="bottles">
  <img class="bottle" src="https://via.placeholder.com/321x620">
  <img class="bottle" src="https://via.placeholder.com/321x620">
  <img class="bottle" src="https://via.placeholder.com/321x620">
</div>

我调整了图像大小以适合片段预览，但您只需使用负边距即可获得您想要的效果。
