First the rendering:

[Processing] The picture scrolling carousel here has been slightly processed: when you click on page 1 on page 5, the picture scrolls one by one instead of 2-3-4 -5 (This kind of multiple scrolling will make you dizzy);

The implementation method is:

The rest is to share the source code:

The structure must be consistent; when calling multiple times, just assign different ids or class names to the outermost layer
*/
/*----Parameter
@ wrap [String] The class name or id of the outer element
@ auto [Boolean] If not set, the default is not to play automatically; if set to true, it will play automatically
@speed [Number] Switch images every few seconds, the default is 4 seconds
