The example in this article describes the pseudo paging effect code implemented by jquery. Share it with everyone for your reference, the details are as follows:

The jquery pseudo-pagination effect introduced here works perfectly under Firefox. There are some problems under the entire IE series. The jQuery1.7.2 plug-in has been introduced. There are rich comments in the code. I believe it will be of great help to learn jQuery. I look forward to everyone focus on.

The screenshot of the running effect is as follows:

The online demo address is as follows:
