I\'ve figured how to align the menu items to the right, but when resized the navbar-toggler doesnt appear.
Code:
The code is fine, however I'd stay with the documentation and replace button just after opening tag because it may have something with js loading.
EDIT: I inspected your website once again and found the button, top right corner! Now all you have to do is change its color and position. Use google chrome dev tools (f12) and searh for it while your window is resized.
