Has anyone else used a fixed header (sticky) and noticed the slight jump in the web page when you scroll down (safari desk, safari mob, chrome mob) Desktop Chrome and Opera ok. Just wondering if there is a way to overcome it.
Don’t think there is much you could do. Blocs (Bootstrap 3) uses a position fixed to make the navigation sticky.
As all the “mob” on iOS? Apple only allows Webkit browsers on the iPhone and iPad. So Chrome and Firefox versions for iOS use the same engine as Safari.
