Reply To: Hide/reveal header on scroll (works but a bit jumpy)

[grimski]

As an update to this, it looks like the “jump” caused if you scroll down too quickly is caused by the opacity value. In addition to the invisible and detached classes being added by the javascript in quick succession.

.invisible has a value of opacity: 0; and .detached a value of opacity: 1;. My guess if that the navigation hasn’t moved itself fully off screen before the opacity is adjusted, making the element visible again?

Any ideas?
