Hidding banner image on Mobile

Site URL: https://www.lauramichelledigital.com

Hi there, I'm trying to hide the complete top banner section on my mobile site, but I can only find the code for the block id which is hides the big logo image, not the background image.

Can somebody help me with the correct code snippet please?

Is that correct, adding  specific page (adds to one page only). Pages -> Gear Icon next to the page -> Advanced

<style>
@media (max-width: 640px) {
  #lmdigital {
    display: none;
  }
}
</style>

Yes it works, thank you very much! 😄
