响应式CSS浮动以垂直对齐，无需在顶部留出任何空白。

Question

我正在创建一个响应式网页。我有两篇文章浮动在左侧，两个旁注浮动在右侧。我希望这两个旁注与第一篇文章在顶部对齐。最初，旁注与文章完美对齐，因为我将旁注放在两篇文章之间的HTML中。

但是，在制作响应式页面时，我发现当我尝试将旁注折叠到页面底部，位于文章下方时，它们会显示在两篇文章的中间，而我想要旁注出现在两篇文章下面。因此，我将旁注移到了HTML页面底部，从而导致了问题。

我已经尝试清除浮动，并使用inline-block显示文章和旁注，但无法使其正常工作。

编辑：有人建议（然后删除了他们的回复？）绝对定位旁注。我已经尝试过这样做，但我觉得它会破坏响应式设计，所以如果可能的话，我想避免使用它。

这里是JSfiddle。

我建议使用弹性盒模型来实现您想要的效果。

删除所有浮动。

将包含元素<main>转换为弹性盒容器：

main {
    display: flex;
}

将所有左侧内容放入<div id="left">中，将所有右侧内容放入<div id="right">中。

现在让我们从这些div中移除grow和shrink属性。

#left, #right {
    flex-grow: 0;
    flex-shrink: 0;
}

现在，当您想要使用移动布局时，您可以将媒体查询设置为flex-direction: column;和flex-grow: 1;，这样右侧内容将下移到左侧内容下方。

您可能需要将分配给每个文章和旁边的某些属性移动到它们各自的左/右列标记中。

这是一个jsfiddle 这是一个有关flexbox的好参考。
