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。
Link to the changed page to view
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:
position: absolute;
left: 50%;
top: 50%;
来自 .wrapper
元素。left: -50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
-moz-transform: translateY(-50%, -50%) transform: translateY(-50%);
来自 .centered
元素。justify-content: center;
至 .d-flex
和 #offers
元素。关于html - 将卡片列表正确放置在网页元素下方,剪裁问题,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/49198942/
