Bootstrap practices-minor issues, major bugs, and bootstrap bugs

I wrote an example by referring to the Code in the book to implement single-line navigation of a large page. The shrink button is displayed on a small page, but it cannot be used. I don't know what went wrong.

There are not many codes. Come on again. When I wrote about the navigation, I suddenly found that a <nav> label was unfamiliar, and it was not surprising that the Code function could be completed.

If you are so careless, do you still get used to it. Subconsciously writing nav into a div, which makes subsequent functions unfeasible.
