🎓 Did you know I have courses? Both free and premium ones: kevinpowell.co/courses?...
Infinite scroll animations for things like logos are relatively common these days, but there is a lot that we can do incorrectly when making one, so I decided to try and make one that respects prefers-reduced-motion, and is progressively enhanced with just a couple of lines of JS to add in the functionality (and duplicate content that we’ll need).

The reason you can manipulate properties and attributes of elements created with JS is that a DOM element is just an object in JS, the difference is it does not have a context (like a parent element, etc.) before it's added to a document. Everything else is there as soon as it's created. You can even add event handlers and trigger events on it!

Hey Kevin, once again great script, thank you! The moment I saw this idea I thought, "why stop with left and right?". I just played around with it, basically I duplicated the "scroll" animation, renamed it to "scrollv" and changed translate to translateY A CSS query to set the list elements to block when direction is up or down, a little CSS manicure and it works already! Currently I still have a small timing problem to fix, but I am so happy about this solution already. You just are the man!

Kevin, I've used clamp() for the column-gap value which allows me to have the scroller span any viewport width whilst keeping the column-gap responsive. I then added clamp() - with the halved values - to the calc() function. Works great! I was initially having a nightmare getting this effect to work properly until I came across your tutorial. Your solution using calc() with the translate and gap value to correct the animation glitch is brilliant. Thank you!

@paulab9310 6 ай бұрын

Hey @Labastidaa, I did the same thing! I am using this ininite scroll in my current React project, I decided to go with a separate CSS file for the component I have the scroller on. My only issue is is that the animation seems to work for me only when I hit save on my .js file. If I refresh the page then it all breaks and it does not look that pretty. Should I be adding some sort of hook for it? How did you get that .js file to mont every time you refresh the browser?

you might also add the standardised `dir` attribute for RTL/LTR content flow to keep the internal order of things and the right to left animation. You then use that attribute for your CSS selector.

you probably already know this, but you can shorten the gradient in the mask by using -webkit-mask: linear-gradient(90deg, transparent, white 20% 80%, transparent); so you don't need to write "white" twice

If you track the parent's width and the width of the children and put the `forEach` that adds items into a `while` loop, you can continue adding them until there are enough items to eliminate any gaps, regardless of the size and number of child elements.

rather than adding the list individually within ul , u can create a variable with the list items and a function that concatenates a list with itself. Now within the ul tag, u can map through the concatenated list items (using the function so it doubles), and create a list tag for each.

@leehoss 10 ай бұрын

Nice video - would be good to show in vertical scrolling as well - I assume it would work the same way. Additionally be good if the scroll speed could work of the inner scroll width so you could get consistent speed regardless of content size :)

So good, seeing the animation depend on "Reduce motion" not being enabled. And good to see `aria-hidden="true" `being added to the duplicated items, so a screen reader user wouldn't have to navigate through them. But what if the images were wrapped in links? The links would still be in the focus order so a keyboard user would still have to navigate through them all. At first I thought the solution would be to use the `inert` attribute instead of `aria-hidden`, making them both hidden from screen readers and non-interactive. However, that would prevent cursor/touch users from clicking on the duplicated links; awkward. The solution is to do what was done before `inert` was supported, add `tabindex="-1"` to the duplicated links. As long as we're thinking about keyboard users, how awkward is it to be focusing on links that are animating? That can be addressed by adding a couple of `:focus-within` rules, one to change the `overflow` from `hidden` to `scroll` and another for the `animation` property so it only animates when `:not(:focus-within)`.

@KevinPowell 10 ай бұрын

I don't think I'd ever use something like this for content I expect the user to interact with. Carousels where the user has control are problematic enough, something like this that scrolls by sounds like a nightmare from a UX perspective, even for fully abled users using a mouse. That said, I love that you thought about it and came up with some valid solutions to make it work, because you just know a client is going to ask for that 😅

To improve JS part a bit, you could add all duplicate nodes to DOM in one go - by first creating a Fragment, appending nodes to it, and then appending fragment to scrollContent. Only one DOM modification instead of many, would save some milliseconds on initialization of this scroller.
