javascript - 制作两个按钮，使 div 随机放置

问题描述

我留下了一个问题，因为编码时出现问题。按下按钮时，方形 div 将被放置在随机位置。

按钮的位置取决于屏幕的比例。▾请与图片核对设计。▾</p>

在此处输入图像描述 在此处输入图像描述

通过多次编码，我考虑了使用哪种结构并继续编写下面的代码。

在手机屏幕上，我将桌面上的按钮隐藏起来。我制作了另一个只能在手机屏幕上看到的导航栏，并制作了我之前提到的按钮。因此，当我在桌面屏幕比例上观看时，方形 div 不是随机位置，而是始终位于顶部。

我真诚地希望你能告诉我问题是什么。

而且我不是编码专家，所以如果您能用特定的代码解释它，我将不胜感激。

先感谢您 ！
