Remove Line above header and header size in mobile

Hi,

I have two problems I actually cannot fix:

  1. I cannot find a solution or the code, where I can remove the black line above the header. Any idea?

  2. On mobile the header image does not adjust size. Did I miss an adjustment?

This site is just a test site, and will be removed when ready, but I need these options for the final project.

Thanks in advance! :slight_smile:
