How to put menu on bootstrap 4 slider?

Question

css

Hello. I had a problem, I can't put a transparent navbar menu on the bootstrap 4 slider. It turns
out that the menu is at the top and the slider below it

Answer 1

Packed. Wrong structure. The header should not contain the slider and added a couple of lines of css

Answer 2

To your code I would add a menu fix

<nav class="col-lg-8 offset-lg-2 navbar navbar-expand-lg navbar-dark fixed-top">
