Few questions about themes

[germangaming]

We recently using Nodebb forum software for our community and we are very happy. We need some help with our theme. We looked at some other communities and we want to know a little more about them.

Question 1.
What are these themes called and how can we install these?

bethesda.net
kaas.wtf
focus-home.com

Question 2.
We want a different theme for our mobile visitors. Can we install a different theme for mobile visitors?

Question 3.
Can we get for 750 euro a custom theme made by you and get a combination theme bethesda.net and kaas.wtf?

Thanks for your attention I’m looking forward to your reply.
