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).

"I help people fall deeply, madly in in love with css." You're succeeding every time! Thank you for all these gems!
80% of my CSS skills, I have learned from you Kevin, you're the best buddy, thank you for these amzing videos ☺
Same
LOL 80% of my CSS skills i have learn from THIS video!😂
I know You don't do a lot of JS video, but man, when you do, they are beyond awesome.
Thank You for the free knowledge!
I love the way you setup things and how you explain it so well even in JS. Thank you for these videos as always!
I was just looking for this kind of animation yesterday, found few solutions but neither of them with an explanation. Now I got the idea behind it and also the reason why my infinite scroll had this kind of "jump" between the first set of icons and the second. Thanks a lot!
Probably my favorite of all your videos I’ve seen. Thank you for sharing this incredibly useful content!! Kevin, you’re the best!
Kevin, you make me fall in love with CSS each time, I visit one of your videos . thank you so much for the value! 🙌
Hey Kevin you are a star. This logo animation was exactly what I needed for my current project. I didn't know where to begin until I saw your CZcams video. Thank you one more.
Thank you Kevin for this informative video. 2 years ago I had a requirement to implement an infinite scroll component to display brand logos. I searched in internet and youtube but never found a proper guide / implementation. If I had this video 2 years ago, it would have saved me a ton of efforts, time and stress.
Couldn't be a more perfect timing for me. I've been thinking about adding such a slider to my art portfolio website. Appreciate your work man! ✨
Man? How dare you assume his gender?!!?!?!
Lmao. Just kidding. Totally agree.
@@webrevolution. I am making a meme video on America'a gender crisis.
I got shocked when I saw multiple gender options on Netflix's software Engineer job application lol
Literally same
You are not the only one Same here😂
Thanks Kevin, you've explained really well the concepts behind this animation.
As always, thanks for the great content Kevin.
You're the best, Kevin! Thanks for the detailed tutorial.
Always on point, professional explainations, great takes, great work!
Ok, this is the best video so far in this area! Thank you so much!!!
As always, THANK YOU Kevin!!!
thanks for this amazing video Kevin. Loved how thorough the lesson was. I'm gonna customize and implement your technique in my University's final project.
Everytime I have a problem I realize you already had the same problem and overcame it. Thank you for lighting the way.
It worked perfectly for me! Awesome tutorial! Thanks a lot.
You are the goat, great lesson, really informative and upbeat!
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!
Thankyou my CSS master, you are the most helpful guy in youtube.
Hey man the tutorial was awesome. Thanks for share your knowledge 🎉
Well done, great explanation
Thanks so much for this, Kevin!
I had to built this last week and had a hard time, wished I had found your video before haha Merci Kevin!
This is so lovely. it's like magic!!
@KevinPowell this is great demo! I added this code to pause the animation on hover.
.scroller[data-animated="true"] .scroller__inner:hover {
animation-play-state: paused;
}
This is really wonderful so user don’t have to “chase” the button on screen, especially if the animation is any faster than what Kevin showed in the video.
good job!
Great Job, I tried it and it's working fine.
Wow, that's so amazing, I think it was so complex, but after I saw your video, understood it so easy (sorry for my English)
Thank you my friend. Very useful and gives the site more interactivity.
wow, amazing effect scroll list item, thanks for sharing
okay now working, thankyou kev
I love your videos so much!
Thanks mate, well done! I just re-created it in nextJS using your code
The object returned from matchMedia has a "change" event, by the way.
Using that, one can react to changing user (and emulation) settings without reloading the page.
now i see , you are leveling up your animation skills
Thank you! I have looking for this feature 😊
this is pretty much exactly what I needed for a project I'm working on, now to just stop procrastinating and actually get to coding
Thank you Kevin!
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!
You really helped me, thanks a lot
I have literally just struggled to build exactly this in a project.
Now im going to have to go refactor it because your solution is so much cleaner and simple to what I did 😂
Thank you so much, it´s amazing
thank you so much for the knowledge
bro you are the king, thankssssssssssss
Great tutorial Kevin, I followed this to create a React component and tailwind styles
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?
Mhuaaa 😘😘😘😘😘 ... Heaven-sent implementation
Wonderful! Thanks!
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!
Do you have a codepen with your coded version? Would be great to see how you did that! :)
Thanks for this tutorial Kevin! Now I have to go and change three logo scrollers on my current project because they all use duplicated content as a solution. It should help page load speed too.
Hei Kevin, You are not only boss of CSS but also boss of JS. Best wishes.
I am an architect, but I love CSS too. Your Videos are Awesome! Thank You!
Same here! Cheers for us rare species 🎉
Just amazing, jussssttttt Amazing. As a beginner who want to start in industry , I hope I get a senior like you. Respect 🚀🚀
Another masterpiece ❤❤
awesome kevin, good job 👏
I'm currently working on a svelte project and need this option the the website i did it. with typescript , svelte , tailwind, skeleton + css.
i really enjoyed! ❤
thanks man , thanks mush love
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.
Thanks Kevin!
I have been trying to do something like this for about a week now. Tried to use a queue for duplicating the items, tried all kinds of weird animations and nothing worked, you really saved me
an incredible class
Thank you so much!
Perfect video!
I hate scrolling sliders because whenever I have to create a new one I forget what I did before. Adding this to my playlist!
Respect man 🙌
This one was very cool.
Hey, I learned something today. 👍
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.
Awesome video! Could be nice making that as a webcomponent.
beautiful thing godfather, thanks thanks 👍
That's what I about to ask for ❤
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.
can you share the code you mean? I have a problem when the items are not enough to fill the container. I want to duplicate the items before finish the first cicle.
amazing video
Thank you!!!
pretty neat!
hey, it works great, is there any way to add option that we can scroll also scroll manually with mouse/touch?
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
One of those things I know when I see it, but never remember that we can do when I need to do it myself 😅
@@KevinPowell 😂😅
How can i adjust that to us it in a vertical way ? thanks so much for ur works!
man, you save me. Every time i was creating a marquee i have the issue with the sudden cut of the rotation.
A _responsive_ version with no max-width would be ace!
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)`.
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 😅
Awesome!! 🤩🤩🤩. Can you do another version, like with previous and next button? Thanks man!
awesome sauce
esta bueno el contenido, lo he adaptado para Angular y que cubra el 100% del espacio del contenedor, gracias
Lovely 😍
It's amazing, is it possible to add and event which speed up the scroll of text when we scroll the page and slowly comeback to normal speed, and the increase in speed is also linear.
And also change the direction if scrolled up and vice-versa
Hi Kevin. Can you, or somebody in the comments, explain how it is possible to change the background of the div gradually based on how much of the section is scrolled? I have 4 DIVS in one section and one sticky div with arrow icon inside it. Now I want to change the background of every div gradually when the arrow points to it. So if the arrow is in the middle of the div the opacity of the background will be 1 and if it is far from the middle the opacity will be lower until it becomes transparent. Is it possible to do this with CSS only? The problem is that i have 4 divs and each of them should change background based on how far the arrow is from the middle of each div.
Muchas graciasssss!!!!!!!!!!!!
About ten years ago, a client asked for a website made in sections that had a side scroll. As much as I tried to convince them otherwise, I had to. It was a cool challenge. I used parallax in some parts. Usability 0, style 10.
Much appreciated. Just an idea suggestion - can you create this in React Next JS with Typescript and Tailwind CSS?
The GOD of CSS🚀
Thanks for the video Kevin. Question: Does Firefox have a Ctrl+Shift+P type option in dev tools? I can't find reduce motion in FF dev console.
I got it to work in Chrome like you did though. Chrome is way better for dev tools
How to enable drag functionality for an image so that when you press and hold on it and move to the right, the direction changes to the right or reverses.
how would you suggest to make it if we want it to be able to drag the scroll?
Hello! This is a great video, you explained everything so so well (Like you always do haha)!! I was curious, how can i implement the javacript file if I am using react? Like i know i can have JS files along the JSX files that react uses but how would i call/import the JS file? Would I have to do the classic script tag on the html file that every react web app has?
i was wondering that too! any solutions yet?
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.
Trying to learn more JS. Do you have a codepen or link to an example of this? Would be great to see! :)
hi. thanks. I small doubt, how to get this working with full width instead of 600px?
Hi Kevin, wanted to say thanks - you've been really helping me out as I'm building my own website
How would it work for a vertical slider instead?
I remember trying to add a marquee like this in one of my first projects and suffering because it didn't line up in different screen sized 😭
