Change sticky header on mobile

Hi @HB-themes,

I would like to change my sticky header on mobile devices only, so visitors will be able to see more of the page and have a more modern approach.
In order to achieve this I would like the sticky header to only show the hamburger menu with a transparant black background. Therefor I would like the logo and container background to be transparant. Could you help me achieving this? If this would be a paid option, how much would it cost?

Kind regards,
Boaz
