I made this page for my website that I am already working on with the help of the video. The whole video was great and really resourceful, there is just one problem that I am facing. You can see in first image the header is appearing as a white separate section. I wasn't able to merge it with the main banner like you did in the video. I tried adjusting the margin to negative but it was looking really weird. I don't know how to fix this issue.
