I am trying to pick up my coding after a short break and now i stumble upon the problem of the hamburger menu not collapsing and expanding. keep in mind this is work in progress i have to source file that i got from the course i am following but i dont see any difference between them besides of course the navbar-light etc (styling) i have uploaded it to github and i hope somebody would like to help me. and if you have a solution i would like to learn from where i went wrong. thank you all for your time

Yeah, you forgot to add some script tags related to bootstrap. I updated your code. Check your github rep. (youll see the updated code in a new fork. To see that, open your repository, then click to "insights". Then you'll see "forks" at the end of the side menu).
