css - 响应式 CSS float 以垂直对齐，顶部没有任何空白

Question

我正在创建一个响应式网页。我有两篇文章向左浮动，两篇旁白向右浮动。我希望这两个旁白在顶部与第一篇文章垂直对齐。最初，旁白与 HTML 中的文章完全对齐，我将旁白放在两篇文章之间。

但是当使页面响应时，我发现当我试图将旁白折叠到页面底部、文章下方时，当我希望旁白显示在下方时，它们出现在两篇文章的中间这两篇文章。所以我将旁白移到了我的 HTML 页面的底部，因此我的问题就产生了。

我试图清除 float 并使用内联 block 显示文章和旁白，但我无法使其工作。

编辑:有人建议(然后删除他们的回复？)绝对定位旁白。我曾尝试这样做，但我觉得它会扰乱响应式设计，因此我想尽可能避免这样做。

这是 JSfiddle .

我建议使用灵活的盒子模型来完成你想要的。

删除所有 float 。

将你的包含元素 <main>放入 flexbox 容器中:

main {
    display: flex;
}

将所有左侧内容放入 <div id="left">和你所有的右侧内容到<div id="right"> .

现在让我们从这些 div 中删除增长和收缩属性:

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

现在，当您想使用移动布局时，您可以设置媒体查询 flex-direction: column;和 flex-grow: 1;并且您的右侧内容将下拉到左侧内容的下方。

您可能需要将您赋予每篇文章的一些属性移到它们各自的左/右列标签中。

This is a great reference for flexboxes.
