I’m now working on the project Build a Product Landing Page and my idea is to copy some landing page, because I terrible with the “design”, In that process I found this template: http://demo.harbourthemes.com/demo/olli/index-1.html which I think is very cool, and I want to replicate, now I’m just working in the navbar, in the effect to change when the scroll down, and this is my progress: https://codepen.io/aasanchez/pen/ERJJKX but I cant find the way how to replicate the transition in the example, the slow slide down of the new color…
Any help?
