Please help centering content for the larger screens

Hello!

I‘m happy with my websites mobile version, and with normal screen size version but when I check it on the big screen everything just gots stretched over the whole screen. 

I would like to get the content of my site centered, for example like on this website: https://www.kyliehowarth.com

Can someone tell me please, is it possible to add to css to make content centering when the screen is bigger than normal size instead of stretching everything and just making a lot of empty space?

Can you share your website URL?

There will be a setting in your website styles that limits the maximum site content width.

Thank you dear Zygmunt, 

Sorry for not sharing the link immediately – I added it to the post in the URL field but didn't know it won't be showing in the post itself

The website is:

lemishka.at

Thank you! It worked!

Is it also possible to apply the same to header to align it with the content of the website for larger screens?

But just to the content of the header(navigation bar and logo) – as I have gradient there and when I tried to limit the width with css it also affected this gradient part.

Thank you!
