Scroll shadows are when you may see just a little inset shadow on components if (and provided that) you may scroll in that course. It’s simply good UX. You possibly can really pull it off in CSS, which I feel is superb and one of many nice CSS methods. Besides… it simply doesn’t work on iOS Safari. It used to work, after which it broke in iOS 13, together with another helpful CSS issues, with no reason why and has by no means been fastened.

So, now, if you happen to actually need scroll shadows (I feel they’re further helpful on cellular browsers anyway), it’s most likely finest to succeed in for JavaScript.

Right here’s a pure CSS instance so you may see it work in all browsers besides iOS Safari. Screenshots:

I’m bringing this up now as a result of I see Jonnie Hallman is running a blog about tit once more. He talked about it as an superior little element again in Might. There are specific interfaces the place scroll shadows actually further make sense.

If the scroll space isn’t all the best way scrolled, present the underside and proper shadows. With this in thoughts, I attempted the only, most straight-forward, and least intelligent method by placing empty divs on the prime, proper, backside, and left of the scroll areas. I known as these “edges”, and I noticed them utilizing the Intersection Observer API. If any of the perimeters weren’t intersecting with the scroll space, I might assume that the sting in query had been scrolled, and I might present the shadow for that edge. Then, as soon as the sting is intersecting, I might assume that the scroll space has reached the sting of the scroll, so I might conceal that shadow.

Intelligent intelligent. No stay demo, sadly, however learn the publish for a number of further particulars on the implementation.

I do suppose if you happen to’re going to do that it is best to go the IntersectionObserver route although. Would like to see somebody port one of the best of those concepts all collectively (wink wink).
