CSS 具有固定大小滚动的网格：如何解决未显示底部 margin/padding 的问题？

Question

编辑:

所以我看到了重复的link，在我看来，这个问题是解决你给定大小（固定宽度或固定高度）的问题。

原始问题的解决方案更多是关于使用 hacky 方法修复容器。我决定采用不同的方法来解决它，同时解决我自己在这个问题中提出的问题。

在CSS中，当使用display: grid和fixed height时，打开overflow: auto，你可能会得到这样的布局，如下所示：

.scroll {
  overflow:  auto;
  background-color: #bbddee;
}

.container {
  padding: 10px;
  display: grid;
  grid-template-columns: 1fr;
  grid-row-gap: 10px;
  height: 420px;
}

.itemContainer {
  border: 1px solid #efefef;
  padding: 10px 20px;
  background-color: #fff;
}

.itemTitle {
  text-align:center;
  margin: 0 auto;
}

.itemLink {
  text-align: center; 
  margin: 0 auto;
}

<div id="retailerContent" class="tab-pane fade in active show">
  <div class="scroll">
    <div id="retailerOffersContainer" class="container">

      <div class="itemContainer">
        <div class="itemTitle">15% Off Room Essentials Cubes &amp; Bins</div>
        <div class="itemLink"><a>Get Offer&nbsp;&gt;</a></div>
      </div>
      <div class="itemContainer">
        <div class="itemTitle">15% Off Room Essentials Cubes &amp; Bins</div>
        <div class="itemLink"><a>Get Offer&nbsp;&gt;</a></div>
      </div>
      <div class="itemContainer">
        <div class="itemTitle">15% Off Room Essentials Cubes &amp; Bins</div>
        <div class="itemLink"><a>Get Offer&nbsp;&gt;</a></div>
      </div>
      <div class="itemContainer">

        <div class="itemLink"><a>Get Offer&nbsp;&gt;</a></div>
      </div>
      <div class="itemContainer">
        <div class="itemTitle">15% Off Room Essentials Cubes &amp; Bins</div>
        <div class="itemLink"><a>Get Offer&nbsp;&gt;</a></div>
      </div>
      
    </div>
  </div>
</div>

发生这种情况时，会出现滚动列表最底部没有 paddings/margins 的问题。应该如何修改 HTML 和 CSS，以便底部 padding/margin 显示在可滚动的 CSS 网格布局中？

Answer 1

这里有一个解决方案（可能是众多解决方案中的一个），展示了如何使用 display: grid:

解决固定高度 div 底部 padding/margin 缺失的问题

.container {
 padding: 10px;
 display: grid;
 grid-row-gap: 10px;
 grid-template-columns: 1fr;
 width: 100%;
 }
 
 .itemContainer {
 border: 1px solid #efefef;
 background-color: #fff;
 max-height: 100%;
 padding: 10px 20px;
 height: 100%;
 }
 
 .itemTitle {
 text-align: center;
 margin: 0 auto;
 line-height: 20px;
 }
 
 .itemLink {
 text-align: center;
 margin: 0 auto;
 line-height: 20px;
 }

      </div>
      
    </div>
  </div>
</div>

这里的主要区别是：

网格容器不应指定高度属性。允许网格自动符合总内容的高度和网格间隙。
相反，使网格容器内的元素具有最大高度，由所述元素的内部内容定义。

这将拉伸网格容器，网格元素内容不会溢出网格容器之外。

Answer 2

这是我在使用 CSS 网格时的修复：

/* Fix scrollbar removing padding-bottom */
@supports (-moz-appearance:none) {
  .container::after {
    content: "";
    height: 1px;
    margin: calc(var(--padding) - var(--gap));
  }
}
