Insure landing page - HTML, CSS and a little JS for the burger menu

I wanted to work on a hamburger menu component that I could use again in other projects I think this one based on Andy Bell's tutorial works well.

I found the top section very difficult to get right (the breakpoint is still not 100% good) especially working with the image. I will try another challenge focusing on images. Any advice on how this could be done better or resources for learning about working with images in layout would be appreciated.

Any other feedback on any points would also be most welcome.
