While designing my navbar I somehow deleted the menu button in mobile so after a few days I copied another one from a new navbar menu. Now when I click on it once it works in mobile. But second time it only changes color but the menu does not open. Any ideas about this?
You have two Nav menus in you navbar and additionally you are using Flexbox which do not play along nicely. You may want to design your own custom navbar if you absolutely need to go the route. Issue is discussed below;
