html - 将卡片列表正确放置在网页元素下方，剪裁问题

标签 html css

我目前有以下网页，它基本上有几个 div 元素一个接一个地放置，并且在移动设备或桌面的 View 中居中，并有适当的媒体查询来改变文本大小。

我最近收到了在当前现有页面下方添加水平滚动卡片列表的要求，我尝试这样做如下:

现在卡片确实出现在包装 div 下方，它们在左侧被完全剪裁。并且无法滚动到剪辑的部分。

此外，如果我尝试将卡片的 div 放在包装 div 之外，它会随机显示在屏幕顶部其余内容的上方。有人可以指导我如何定位卡片列表，该列表的大小也可以增加到当前元素(不包括卡片 div 的页面)的下方，同时不剪裁它。

你可以在桌面上查看它，它看起来很好，在手机上查看它，你会看到它被裁剪了

最佳答案

卡片列表因 flex-wrap: nowrap 而被裁剪属性(property)，you can read about it here . 您需要使用 flex-wrap: wrap相反。

在您的示例中，您需要更改 flex-nowrap来自你的课 d-flex元素(卡片父级)到 flex-wrap类。

更新。我还向您推荐以下操作列表:

  • 删除 position: absolute; left: 50%; top: 50%;来自 .wrapper元素。
  • 删除 left: -50%; -webkit-transform: translateY(-50%); -ms-transform: translateY(-50%); -moz-transform: translateY(-50%, -50%) transform: translateY(-50%);来自 .centered元素。
  • 添加justify-content: center;至 .d-flex和 #offers元素。
