显示侧边栏DIV后--Show**显示解决问题的努力。好的，将失败的尝试添加到question@levizoesch听着，伙计，我们都是来帮忙的，这就是为什么我们费心点击你的问题。但是当你复制/粘贴你的整个代码时，这并没有帮助。没有人有时间去看它。你需要去掉所有与你的具体问题无关的东西，这样我们才能更快地找到答案。当您的html中有脚本标记时，将其分离成javascript部分，而不是将其与html粘在一起。@RayonDabre我没有粘贴我的全部代码。我粘贴了只需要的东西。我对我的问题进行了编辑，以便就我要做的事情给大家提供可靠的观点。我不知道如何解释…………你可以在

@media（最大宽度：768px）{

css块中实现这一点。只需编写代码来旋转和移动div到顶部。
