Solved Making header shrink and get fixed after first Divi section is scrolled down

Hi there!

I'm building a website with Divi: http://thierry-jaspart.com/temp/schreck/art/discography/nikolas-schreck/

As you can see I followed an Elegant Themes tutorial to make the header appear below the first section. It works fine but I want the header to shrink and get fixed once the first section is scrolled down like on this other website: https://www.muhka.be/collections. Is there a way to achieve it?

Thank you and have a nice day!

 

Thank you very much for the reply. I read carefully the page you sent me but it's not answering my question. Did you look at the two sites I'm talking about?

Thank you.

 

Okay, thank you anyway!
