The Mythic Smooth Scroll plugin is a very lightweight jQuery plugin for adding smooth scrolling animations on single-page websites or on longer posts with various anchors.
The plugin features an optional offset for fixed/sticky headers to make sure it always scrolls beneath the content, as well as an adjustable manual offset amount to determine how far from the header/top of the screen the content will land when scrolled to.
Questo plugin è disponibile per il download da usare sulla tua installazione WordPress ospitata personalmente.
