I am trying to have my navigation bar change from transparent background to a black background when scrolling. Like this template: https://www.templatemonsterpreview.com/demo/58900.html?_gl=1*vx82om*_ga*MTc0ODAzMTI4OS4xNjI3NTcxNDQw*_ga_FTPYEGT5LY*MTYyNzYwNzQ4Mi40LjEuMTYyNzYwODA2NC40Nw..&_ga=2.184031919.825417510.1627571440-1748031289.1627571440 . I have tried the answers from: How to Change Navigation Bar Background with Scroll? and Changing nav-bar color after scrolling? but it does not seem to work for me.
This is my html:
