水平滚动 bootstrap 4

Question

我正在尝试为移动视图 @media only screen and (max-width : 480px) 中的某些卡片设置水平滚动条。我在这里阅读了其他帖子，包括 this one，但 none 似乎对我有用。我想我可能遇到的一个问题是，现在我的卡片一张一张地叠在一起。

这是我现在拥有的：

这就是我需要实现的目标：

.mobile-card-container {
  display: block;
}

.card-background {
  background-color: #ffffff;
  border-radius: 6px;
  margin-top: 16px;
  height: 100px;
  -webkit-box-shadow: 0px 2px 4px 1px rgba(0, 51, 102, 0.1);
  -moz-box-shadow: 0px 2px 4px 1px rgba(0, 51, 102, 0.1);
  box-shadow: 0px 2px 4px 1px rgba(0, 51, 102, 0.1);
}

Answer 2

要解决此问题，您必须更改 Bootstrap classes 的默认行为。我们必须在最小媒体屏幕的卡片容器上使用 flex-nowrap，并将 overflow-x 样式更改为 auto。综上所述，我们将使用接下来的主要变化：

CSS

@media only screen and (max-width : 576px)
{
  .mobile-card-container > .row {
    overflow-x: auto;
  }
}

请注意，我使用 max-width: 576px 是为了与当前的 Bootstrap Breakpoints 兼容。

HTML结构

<!-- Mobile Card Container -->
<div class="container-fluid mobile-card-container">
  <div class="row text-center flex-nowrap flex-sm-wrap">
    <!-- Cards will be here -->
  </div>
</div>

因此，对于 XS 屏幕设备，flex-nowrap class 将与先前定义的样式一起应用，接近您要搜索的内容。在其他类型的屏幕（SM、MD、LG）上，Bootstrap classes 的默认行为将被保留（注意 [=36= 的用法]flex-sm-wrap class).

最后，您可以查看下一个工作示例（在全屏模式下使用 windows 调整大小）：

@media only screen and (max-width : 576px)
{
  .mobile-card-container > .row {
    overflow-x: auto;
  }
}

.card-background {
  background-color: #ffffff;
  border-radius: 6px;
  margin: 16px 5px;
  height: 100px;
  -webkit-box-shadow: 0px 2px 4px 1px rgba(0, 51, 102, 0.1);
  -moz-box-shadow: 0px 2px 4px 1px rgba(0, 51, 102, 0.1);
  box-shadow: 0px 2px 4px 1px rgba(0, 51, 102, 0.1);
}
