Create Sticky Menu in Debut/No theme.css. file in Assets folder

[bennycarts]

I need to create a sticky menu for my debut theme but all the instructions online tell me to edit in the theme.css file and the theme.scss.liquid file. 

I don't have these files.

Can you help me add this feature please?

Thanks for responding.

As I said in the original message, I don't have the "theme.scss.liquid file".

I've noticed a lot of other people posting this in the community too.

So my question is: how do i create a sticky menu without the theme.scss.liquid file?
