There are several problems with the original method: first, Js Code redundancy. the Tab on the navigation bar uses js to achieve redirection rather than hyperlinks, and the navigation bar uses fixed to locate the navigation bar, but it is not set to horizontal center, but changes the left value in JS to center it.

After re-writing this page with Jquery, I found that there are several problems with the original method:
1. First, Js Code redundancy. the Tab on the navigation bar uses js to achieve redirection rather than hyperlink;
2. The navigation bar itself is positioned with fixed, but is not set to horizontal center. Instead, the left value is changed in JS to center it.
Problem 2 is the cause. When the browser window size changes, the position of p in the browser changes, this makes it impossible to dynamically locate the fixed navigation bar through p in the page.
The final code change is as follows:

The Code is as follows:
