I copied this into a new page and the tabs don't navigate.

http://jooy.org/one/TabMenu.html

I copied and pasted several times. Tried internal css and external. Different browsers. Still the links don't function. It seems to have all the correct elements, but it's not working.

1- download full version of bootstrap v.4

download it here -> https://github.com/twbs/bootstrap/releases/download/v4.0.0/bootstrap-4.0.0-dist.zip

2- install jquery v.3.2.* (minimum)

3- insert the following lines of code in order

<link href="bootstrap.min.css" rel="stylesheet" />

<script src="jquery-3.2.1.min.js"></script>

<script src="bootstrap.bundle.min.js"></script>

thank you
