transparancy on mobile and tablet

[Linda MacDonald]

Hey there folks
I would like to have the same transparency that I have on desktop on mobile and tablet. I have set the page to transparent and the section that contains the navigation is also transparent, but for some reason I cannot get that on tablet and mobile: I have tried with:
section with image set to top margin -100 which works fine on desktop, but on tablet and mobile it doesn't work
please find screenshot in links

Hi, double click on your menu, go to mobile design and ajust the topbar color to your needs.

@Wassim ok got it, but I would like to have the top bar completely transparent which I do have on the desktop version, but if I do a transparent background on mobile that also removes the background from the sidebar menu... meaning when you scroll you cannot see the menu ...is there a way to target the css for the top bar only? perhaps give each a custom class?
