将弹出窗口粘贴到其位置答案

【问题标题】：Stick window pop-up to it's position将弹出窗口粘贴到其位置
【发布时间】：2022-10-23 16:21:09
【问题描述】：

因此，我创建了一个在单击按钮时出现的窗口弹出窗口。如果重要，内容窗口会显示视频。现在，问题是当窗口显示/加载时我仍然可以滚动。现在，我正在考虑保持这种方式，因为代码是这样编写的，因此您可以单击网站上的其他任何位置，然后窗口弹出窗口消失。但是，问题是当我滚动时弹出窗口随之而来。如何使弹出窗口粘在它的位置？

【解决方案1】：

fixed 定位意味着它固定在视口上，无论您滚动它停留在哪里，都可以使用absolute 定位，它相对于文档正文“修复”它（除非另有说明）。您可以阅读有关定位here 的更多信息。
