Responsive using flex box, bootstrap for responsive navbar

The carousel was the most hardest part, I misunderstood the overflow property. I added overflow hidden to the body tag which conflicted with the carousel container, furthermore the background image is pretty hard to position. if one is familiar won how to position an image please feel free to comment.

Lastly after a lot of practice I finally understand that making a layout before adding any text is the best practice, use background colors like #ccc and dark gray for layout creation
