![]() ![]() The element can have a fixed, non-percentage based height (ex. If the element has been assigned a height of 100% or overflow: hidden, Smooth Scroll is unable to properly calculate page distances and will not scroll to the right location. I've decided to respect user preferences of developer desires here. In browsers that surface that setting, Smooth Scroll will not run and will revert to the default "jump to location" anchor link behavior. Smooth Scroll respects the Reduce Motion setting available in certain operating systems. This isn't really an "issue" so-much as a question I get a lot. ![]() If you want to maintain the old scroll animation duration behavior, set the speedAsDuration option to true. Scroll duration now varies based on distance traveled. Var scroll = new SmoothScroll ( 'a', ) What's new? You can download the files directly from GitHub. Otherwise, use the version with polyfills. If you're including your own polyfills or don't want to enable this feature for older browsers, use the standalone version. There are two versions of Smooth Scroll: the standalone version, and one that comes preloaded with polyfills for closest(), requestAnimationFrame(), and CustomEvent(), which are only supported in newer browsers.

When using a site - the user should never be made to question or think about the interactions unnecessarily.Smooth Scroll is, without a doubt, my most popular and widely used plugin.īut in the time since I created it, a CSS-only method for smooth scrolling has emerged, and now has fantastic browser support. Breaking or screwing with basic website operation on such a page could well confuse the user or make them question what is going on since the page appears to be a normal one. In your own example, the page is plainly and clearly a 'normal' page. However, care should still be taken with the 'feel' of the scrolling - the first of the examples above is fine in this respect, but the others feel a little too elastic. This type of interaction can indeed can be very effective. If this is self evident from the page - the user will probably not have the expectation of scrolling working in the normal manner.

Note: Your callback routine must itself call requestAnimationFrame() again if you want to animate another frame at the next repaint. The method takes a callback as an argument to be invoked before the repaint. The window.requestAnimationFrame(**)** method tells the browser that you wish to perform an animation and requests that the browser calls a specified function to update an animation before the next repaint. Notice that we are calling the smoothScrolling function through requestAnimationFrame() function. The smoothScrolling function runs recursively changing the translate property on the " scrollingContainerRef div" whenever the user scroll. This useEffect runs only once and calls the smoothScrolling function.After passing "position: fixed" to the "parent div", this makes sure that we have enough room to scroll through the whole " scrollingContainerRef div" setBodyHeight makes the height property on equal to the height of the " scrollingContainerRef div". This useEffect runs only if the windowSize changes (if the user resizes the browser).data is not a state because we don't want our react component re-rendering each time we scroll.scrollingContainerRef is used to apply translateY property on the div, on the fly.useWindowSize() is a custom hook that returns the current innerWidth and innerHeight of the window.Import React, export default SmoothScroll Įnter fullscreen mode Exit fullscreen mode
