位置固定问题

发布于 2024-10-05 20:52:50 字数 4235 浏览 6 评论 0原文

您好，我有一个基本的页面设置原型，页面右栏中有一个浮动篮子。

发生的情况是，当用户滚动时购物篮到达页面顶部时，它会应用一个类，将其位置固定到屏幕顶部，直到用户再次滚动到屏幕顶部。

除了一个问题之外，这种方法工作得很好：

当您调整浏览器窗口的大小以使视口小于网页的宽度并水平滚动到右侧时 - 如果您向下滚动页面，篮子会固定其位置，以便与网页重叠页面右侧！

我正在使用的代码如下，希望得到任何建议。提前致谢！

原文

Hi I have a basic page setup prototype a floating basket in the pages right column.

What happens is when the basket hits the top of the page as a user scrolls it applies a class which fixes its position to the top of the screen until the user has once again scrolled to top of screen.

This works fine apart from one issue:

when you resize the browser window so that the viewport is smaller than the width of the webpage and horizontal scroll to the right - if you then scroll down the page the basket fixes its position so that it overlaps the right hand side of the page!

Code I am using is below, would apprreciate any advice. Thanks in advance!
