Hi,

I was looking at some of your free templates. e.g. I liked one for Software company.

Question is: onload of page, navbar is transparent, which is nice feature as it seams like it blends in image, but then as you scroll down, nav element has one more CSS class, "top-nav-collapse". By adding this element, you are adding background color so it acts nice while scrolling.

I've managed even to identify this in mdb.css (sections with navbar:not if I am right :) ).

So, can you please explain me which event, and how do you add this class to this element?

Thank You
