Hi @miladilakila,
Thank you for writing in, the Container that contains the Logo and Menu is set to be hidden on an extra small screen (480px and below). Please see this documentation to know how the Hide During Breakpoints feature works in the Header/Footer Builder.
Add a mobile menu too, as your Inline Navigation Menu is set to be hidden from the medium screens (979px and below).
For mobile menu use either the Navigation Collapsed or Navigation Layered element, then hide this on large and extra-large screens (980px and above) using the Hide During Breakpoints feature.
Hope it helps,
Cheers!
