Hi all, I installed superbike theme and I'm trying to customize it but I can't solve a problem. On other devices all works fine but if I open my website con a mobile phone I have no Main Menù bar (button).

Here the link.

Hi there,
did you read the mobile menu instructions?

Solved with your manual. I missed to set up mobile modules. How can I change background color in the boxes during digitation? I have white background and very light grey for text and it's illegible. Please, see in the serachbox on my home.

The search field can be changed in customizer > Advanced > Search

I've the same problem in all Text boxes! When active they mecome white and text light grey and it is illegible. I'd like to change white background with another color. How can I do?

I told you above you can edit the form colors in customizer:
Customizer > Select your style > Advanced > Forms [more] >> See image attached
