I created a site and made a responsive design. But when I open the site on the phone, the menus in the header section are broken.

I am attaching the code files and the picture of problem (I know i didnt add logo and some pictures to my website)

I did a lot of research and consulted ChatGpt, but my problem was not solved in any way.
