html - Flexbox 不会在浏览器调整大小时换行

我正在尝试让我的 flexbox 在移动设备上调整大小和窗口大小。

对于我的生活,我不知道为什么它不起作用。随着浏览器的缩小, flexbox 应调整大小并环绕到下一行。

随着浏览器窗口分辨率变小,我想将右侧包裹在左侧下方,但我似乎无法弄清楚。

flexbox 右侧的内容被隐藏,并使用 CSS 关键帧从顶部简单地滑入。我猜这可能是个问题,因为 flexbox 右侧的内容 div 基本上是空的

最佳答案

Michael_B 很好地解释了这里的问题。

除了他的回答,我只想说你也在使用绝对 .content ,所以你的 flexbox 不是一个“普通”的 flexbox。

顺便说一句,使用您的 HTML,我试图让它负责。诀窍是删除所有固定宽度。

Bootstrap 是一种可能的方法,但如果您已经开始工作,则可以仅使用 CSS 属性而不使用 javascript(正如您正在做的那样)完成它:CSS 拥有执行此操作的所有凭据,无需框架。这是我的想法。

我尽量不更改您的 HTML。我只删除了 <div id="middle-border"></div>因为你可以在你的 #left-zone .list 中创建一个右边框在box-sizing的帮助下属性(property)......和边界权利,自然而然;)

在您的 CSS 中,我用更简单的不透明度和 translateY 过渡更改了您的动画(我认为您必须在没有其他动画的情况下从 A 点转到 B 点,所以一个过渡就足够了,我认为)。但是,嗯,这不是使用动画的错误,我认为只是在这项工作中使用过渡更简单。

另一个重要的想法是使用 CSS 在 HTML 元素的默认样式中提供更好的跨浏览器一致性。为此,我使用了“normalize.css”:https://necolas.github.io/normalize.css/ )

这是代码,希望对你有帮助:
