html - 填充顶部和填充底部不起作用

Question

出于某种原因，padding-top 和 padding-bottom 不适用于我的#functions div。

我似乎无法弄清楚是什么取消了 CSS 导致的，并且出于某种原因 padding-left 和 padding-right 工作正常。

我希望#functions div 看起来像这样:

我的 HTML 或 CSS 有问题吗？我是不是以错误的方式处理这个问题？

Answer 1

这可以使用 CSS Flexbox 来完成。

作为引用，您的 CSS 应该类似于:

#savefood, #savemoney, #savetime {
  display: flex;
  justify-content: center;
  align-items: center;
}

#savefood {
  flex-direction: row-reverse;
}
