	    column-gap: 10px;
	  }
	  .waterfall-item {
	    break-inside: avoid;
	    margin-bottom: 10px;
	    display: block;
	  }
	  .waterfall-item img {
	    width: 100%;

  <body>
    <div class="waterfall">
      <div class="waterfall-item">
        <img src="img1.jpg" alt="" />
      </div>
      <div class="waterfall-item">
        <img src="img2.jpg" alt="" />
      </div>
      <div class="waterfall-item">
        <img src="img3.jpg" alt="" />
      </div>
    </div>
  </body>
</html>

使用 float: left（float常规浮动，高度固定、不铺满）

html 复制代码

<style>
  .waterfall {
    display: block;
    margin-right: -10px;
    margin-bottom: -10px;
  }

  .waterfall-item {
    float: left;
    height: 300px;
    margin-right: 10px;
    margin-bottom: 10px;
  }

  .waterfall-item img {
    width: 100%;
    height: 100%;
    object-fit: cover;
  }
</style>

使用 flex-wrap: wrap（flex常规浮动，高度固定）

html 复制代码

<style>
  .waterfall {
    display: flex;
    flex-wrap: wrap;
    gap: 10px;
  }

  .waterfall-item {
    flex: 1;
    height: 300px;
    min-width: 200px;
    max-width: 500px;
  }

  .waterfall-item img {
    width: 100%;
    height: 100%;
    object-fit: cover;
  }
</style>

使用 column-count （列数固定，宽高自适应）

html 复制代码

<style>
  .waterfall {
    column-count: 3;
    column-gap: 10px;
  }
  .waterfall-item {
    break-inside: avoid;
    margin-bottom: 10px;
    display: block;
  }
  .waterfall-item img {
    width: 100%;
    height: auto;
    display: block;
  }
</style>

使用 Grid + grid-auto-flow: dense（列数变化，宽高自适应，每个item宽高相等）

html 复制代码

<style>
  .waterfall {
    display: grid;
    grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
    grid-auto-rows: 200px;
    grid-gap: 10px;
    grid-auto-flow: dense;
  }

  .waterfall-item {
    grid-row: span 1;
    overflow: hidden;
    border-radius: 8px;
  }

  .waterfall-item img {
    width: 100%;
    height: 100%;
    object-fit: cover;
  }
</style>

想要高可控效果可借助 javascrpit 脚本实现，列如：Masonry 、Isotope、Justified-Gallery、Packery、bricks.js 、flexImages、jQuery-flexImages、waterfall
