One of the few single-page URL navigation source codes

1. It is very important. There are promotional links in the downloaded source code. Delete them all and replace them with pure official links.

2. Change the default search engine to Baidu, which was previously Sogou.

3. Remove too much useless code, there is too much useless code in it.

4. Modify dead links. The links inside do not need to be opened locally, but need to be uploaded to the server for opening.

5. Remove the previous message feedback source code. It feels useless and requires database installation.

6. This website navigation does not require installation, it can be used immediately after uploading.

This source code is currently the cleanest single-page navigation source code.

All the links inside are /, and the only thing that needs to be modified is the address about us in the upper right corner.
