I would like to create a menu that behaves like the menu on this page: https://www.palantir.com/
Specifically that the menu starts with no fill, and then changes color on scroll down. On our page: http://www.grooooow.com the menu is black with some transparency and is fixed on scroll down, but I’d like it to be transparent and then on scroll down change to white transparent, and remain fixed. Then on scroll-up to top, revert back to no fill color.
I have searched the forums and video tutorials, but can’t find any joy!! Please could you help?!
Thanks very much for any help you can offer !!!
