Flex容器不包装物品[重复]

Question

我正在为我的作业创建一个简单的 flexbox 定价页面，我最终完成了它。问题是当屏幕尺寸减小时定价卡不会换行到下一行我已将 flex-wrap 设置为换行但仍然没有运气。我搜索了这个问题，一些结果说将 flex-container max-width 设置为 100% 会有所帮助，但它没有。我尝试了很多其他的东西，但无济于事。有人可以帮我解决这个问题吗？

Answer 1

您已将卡片的 with 设置为 25%。您需要添加一个媒体查询 (https://wiki.selfhtml.org/wiki/CSS/Media_Queries)，以便您可以在屏幕太小时设置另一个。

.card{
    width: 50%;
}

@media (min-width: 1200px){
  .card{
    width: 30%
  }
}

Answer 2

使用width 的硬代码来换行，如果你想使用软代码，你可以使用@media 用于不同的屏幕尺寸。

根据需要添加边距和内边距

@media 像这样：

@media (max-width: 776px){
  .card {
    width: 48%;
    margin: 2% 1%;
  }
}

@media (max-width: 500px){
  .card {
    width: 90%;
    margin: 2% auto;
  }
}

Answer 3

您必须严格定义卡片的宽度。 25% 是一个相对值，这意味着它将缩小到适合容器的大小。出于美学原因，我添加了一些边距，并添加了flex: 1 0 0 - 它会在必要时增长，不会收缩（如果它不会收缩），并且每张卡片都会从width 中定义的基本宽度增长。如果您不希望它增长，只需​​定义flex:0 0 auto，或完全删除flex 行，然后定义justify-content: space-evenly。

请注意，您也可以使用媒体查询对其进行硬编码。事实上，我建议为您的卡片设置不同的宽度可能会很麻烦，而创建一个固定宽度的卡片托盘可能会更容易。
