First i would like to thank you in advance for your help.
I created a website with the Syndey Theme: https://fromskytoscreen.com
There’s some problems on the mobile version and on desktop with a scaled down screen.
On mobile we have to zoom out to display the full site and on both (mobile and desktop scaled down) the menu don’t look great.
It might be because of added code, i don’t remember exactly what i’ve tried to fix it.
