How to replicate this header?

Hi,

I want to make my desktop and mobile header like Link 1. The Link 2 is my site.

Kindly help me how to achieve:
1. Desktop and Mobile Header same as Link 1.
2. Mobile Off-canvas Menu as per Link 1.
3. Sticky Canvas as per Mobile Header view of Link 1 (maybe for mobile only).

I am trying it myself but not able to achieve it 100%.

Thanks and Regards,

Juned
