Menu: link
I've never seen a responsive menu like this, it has nothing of average queries, I believe the responsive part is created by javascript. Anyway this is not my problem, I want the menu to be responsive before it is. For example, I tested it on the resposinator and more or less at 570px the menu modifies to fit on mobile phones, and I wanted to increase this number to about 760px.
But I looked all over the css and then the javascript no approximate or similar number appears there. Do you have any specific tags that I should modify?
