True parallax with CSS-only is now possible

[@KevinPowell]

Instead of the overflow issue I showed, as a commenter said below, we can use contain: paint; and it works!. Also, I have a general rule that I won't make videos about a CSS feature until it's supported by at least two browsers, but with a polyfill available (linked in the description) I decided to break my own rule 🙂

[@KevinPowell]

@z3rocodes it's definitely a little frustrating, specially considering they used to be the browser that was most often at the forefront. Even more frustrating is the for-profit side of the company that owns the non-profit (it's all a bit of a mess imo) seems to be doing extremely well, so even less reason for the gutting of the team who works on the browser itself.

[@rand0mtv660]

@@z3rocodes If I didn't look at it wrong now on caniuse, both Firefox and Safari are missing both of these features. So yeah it's not just Firefox that's slacking.

[@KevinPowell]

@@rand0mtv660 Safari has put out a positive signal on this though, so it's something that they'll be working on, or might already be working on.

[@Remeroska]

I'm sure safari and Firefox will catch up in 6 months or so. Scroll transitions will be a game changer for many applications, they won't pass on

[@wintercounter2]

Actually, in this case I think it's completely fine to ship the effect to Chrome and Edge users only, because it falls back nicely when there's no support.

[@richardhindle1663]

This will be perfect for my next project. I'll be trying this tomorrow. This video earns a beer on me.

[@KevinPowell]

Thank you so much!

[@Yojmb0]

13:41 I believe you can use overflow:hidden if you instruct the CSS scroll function to bind to the root element - using scroll(root)

[@dannievinther]

In regards to the issue pointed out about setting overflow to 'hidden', you could easily just pass 'root' in the scroll() function, which I guess would create a similar result

I was about to say this as well :)

you are my insperation Kevin, you actually made me change my view on css for the better 😁

[@spatialoptic]

Inspiration for my next website project starting next week! Thank you!!!

[@bibamann]

Attention: if you use npm build tools, the css properties in the live-built (not in dev) get sometimes sorted like for me in Nuxt. The "animation" short-handle overrides then animation-timeline and nothing happens. At least I think it was the sorting. However: You need to setup it step by step: animation-name: parallax; animation-timing-function: linear; animation-timeline: scroll(); to make it work.

[@noahr1545]

Dang, this looks so easy to use as well. Great video as always!! You're the css master 😎

[@mocostartup]

Great video Kevin! Couldn't think of a better example 🤙

[@kingshanaman]

I can't believe how easy this thing is. Thanks for the great explanation 👌

[@NiceChange]

Thanks Kevin. This really helps turn CSS in to art and a very interactive site.

[@bramus]

As you mentioned, the problem with `overflow: hidden` is that it creates a scroller. Instead of creating a named scroll-timeline as a way out of this, an easier way is to simply set `overflow` to `clip`. It does the same as `overflow: hidden`, but where it differs is that `overflow: clip` does not create a scroller. Furthermore, have you checked out `animation-range`? For this demo I’d go for `animation-range: 0vh 100vh` so that the animations are no longer affected by the page length.

[@RondellKB]

CSS is getting so exciting.

[@nilaallj]

The Webkit team has given this spec a positive standards position, so we can count on Safari getting support at some point. Hopefully not too far in the future.

[@howdyhowdyhowdyhowdyhowdy]

It's an exciting time to be a web developer!

[@AjajRajguruAJ]

After reviewing the comments, it seems that not many people including me knows 'contain: paint' versus 'overflow: hidden' well and @Kevin, this could make for valuable video material and would also be beneficial in similar cases. Thank you

[@KevinPowell]

Already planned a video to compare them after this ☺️

[@Remeroska]

Instead of overflow hidden, could you use contain: paint?

[@KevinPowell]

Great question... and it works! I didn't even think of that, very awesome!

[@DeepJasoliya]

Thank you i didn't even know something called contain exist!

[@MrDJsArcade]

Hey Kevin I’m really enjoying your videos! I’m excited to apply it to my site.

[@heavylog1c]

This is like the most awesome thing in CSS I've seen in years. Cuz I like parallax a lot. Fingers crossed for Safari, I hope they will add support for this eventually.

[@zackmalaysia5384]

This is gold..out of the box.. genius

[@proudyy]

I really like the idea of implementing a speed var to modify each single child in there, so that's a mandatory advantage compared to lots of libs doing which create parallax effects. Thanks Kevin 😊

[@nomadshiba]

no need for background on the main content to overcome overflow: hidden issue and no need for adding position: relative and z-index: 0 to main .parallax element to overcome stacking issue. you can just use, isolation: isolate and contain: paint like this: .parallax { isolation: isolate; contain: paint; min-height: 75vh; display: grid; grid-template-areas: "stack"; } tbh when you mentioned overflow: hidden issue, i thought you would mention contain: paint, because i know you know it. i think you just forgot about it.

[@KevinPowell]

You don't even need the isolation, just the contain: paint and it works. Didn't even cross my mind while I was working on it either! Added it to the pinned comment though.

[@nomadshiba]

@@KevinPowell oh didnt even realize, i should have read the pinned comment first😅

[@hoobler08]

Excellent excellent excellent. Thank you, Kevin.

[@Atractiondj]

This video inspires me, how I can create a smooth scroll library with only vanilla CSS

[@gE0013]

The only downside of your approach is the fact that you have to set up things outside the hero area (content background), making it less modular. Not a big deal though, especially considering the root suggestion(s) of the other comments. Brilliant video! It's so cool seeing big CSS improvements with a few lines of code. Thank you!

[@adnanamin3666]

Awesome as always! ❤ Kevin, will you create a navigation menu like Apple's website? Mega menu, sub menu style?

[@clevermissfox]

How did I miss this video?! Maybe I thought I’ve already watched because the project was the same. Very cool. Thanks KP!

[@júliobroliato]

Regarding the `overflow` property issue: instead of using the `overflow: hidden` value, what about `overflow: clip`? I've performed some tests on Chrome and Edge and seems to work: content moved outside the `.parallax` container are not shown and everything regarding the parallax effect seems to have keept working, at least on all the tests I've performed. Or, perhaps, there's a reason to avoid `overflow: clip` altogether that I'm unaware of? Anyway, just to add a litlle about my trials, but I absolutely loved this technique! Thanks for another great video Kevin!

[@tonyblox]

It's a great concept. And that's all it is at the moment. Not supported in firefox, nor safari

[@Wolfeur]

Regarding the overflow issue: have you tried either using `scroll(root)` or `view()`?

[@kevinfisher7032]

Terrific technique, Anytime I can do all my fine tuning live in the browser through the CSS!!! So much of this parallax stuff is about the small details and this gives you so much control. Love it!

[@danstevens1974]

Hi Kevin. Excellent video. In your intro you mention background-attachment > fixed. This does not work on IOS. I was wondering if you have some CSS to make it work? I've been hunting hi and low! So i can have the nice "sort of" parallax effect on desktop, but sadly not on mobile. There must be a work around?

[@pretendlovers]

this makes me excited to mess with parallax effects now on my website :D

[@krzysztofprzygoda7635]

You could calc --parallax-speed based on z-index as var.

[@TAHppled]

Can you set the z-index to a vet like you do with your colors? Make a private property on the parallax that controls the x-index and multiplier, and can be set at the item level. Then you just set the one property, let’s call it __parallax-position or some such thing, and it sets the z-index to 5 and multiples the scroll speed by 5. So it’s going 5 times faster than the background. Not sure if that made sense, but seems a way that you can set it up and only have to fudge a couple numbers on the main parallax instead of on every item.

[@Mahmoudery]

So close to 1 Million subs🎉

[@tomilipin]

Hi @KevinPowell, are you welcoming everybody at the beginning of the video by saying "hello my friend and friends"? What does it mean? Why do you welcome a friend (singular) and friends (plural)? I'm not a native Engish speaker, so please explain. Thanks!

[@jamesgulland]

Brill video, thanks Kevin

[@AllwinSamuel-t5f]

From where your getting those cool images you used in background

[@norboost]

It would be neat to use css variables for the depth of the individual elements and use that to both set the z-index and the parallax speed. That way moving something to the front or back will make sense speed wise as well

[@nekture]

Just use 3D if you want that.

[@Stabruder]

You could scss instead (Sass) It got exactly this feature too, to create variables

[@lukaschylik9131]

Hi Kevin, why don't you use isolate: isolate to create a new stacking context? Wouldn't that work?

[@gardiner_bryant]

Why not clip-path the parallax container?

[@KevinPowell]

Would probably work 😃 . An even simpler solution that some mentioned in the comments is to use 'contain: paint;'.

[@ousssika5359]

thanks for everthing , it will be great if you do a full dashboard admin , with scss , and give your approche to make it happen

[@helmuthpetelin4613]

hey kevin wouldnt the pixel offset break the site on mobile and how would you fix it? Of course there is allways the way to build it for certain displays with media querries. Isnt there a easier solution?

[@KevinPowell]

The multiplier could just as easily be a viewport unit. You could even have the base be 1vh, and then the --parallax-speed: ; values be in vh as well, so it's always adjusting to the space available.

[@VaracolacidVesci]

This is very nice idea. But in real life the parallax fx move the closer items way faster than the one far away (like when on a train, the mountains almost dont move but the trees on the side of the road pass fast. It is like the perspective

[@joeldcanfield_spinhead]

that's set by the parallax scroll/animation multiplier he set for each layer. set them however you like for the desired effect (I agree, I want the farthest back layers barely moving, and forward layers flying past, as on a train)

[@VaracolacidVesci]

@@joeldcanfield_spinhead I do understand the code, I was just saying that the parallax fx is a visual effect due the perspective. and Ofc you can set your fx however you want, but real parallax has rules.

[@KelvinYong77]

Would you not use `isolation: isolate` for creating new stacking context?

[@avneet12284]

You can probably use overflow: hidden if you use scroll(root) not just scroll()

[@arhangelohek-UKR]

What if instead of overflow:hidden; trying to use clipping-mask? 🤔

[@KevinPowell]

contain: paint; will work :)

[@haeinsneins]

overflow:clip works. Because then the element is no longer a possible scroll container @@KevinPowell

[@adamburysek3976]

that i want know too :)

[@GrantGryczan]

If you want to move them, you could just use `position: relative;` on the children instead of `position: absolute;` on the children and then `position: relative;` on the parent.

[@clevermissfox]

Wait, putting position absolute on a grid item makes it relative to its cell, not the grid parent as a whole?

[@KevinPowell]

If they have a defined cell, yup :). If you don't explicitly place them in a cell, then it looks at the whole thing.

[@VeitLehmann]

Wow, this is neat! Maybe clip-path would work for preventing the elements to stick out as an alternative for position: relative and z-index: 0? Edit: clip-path: inset(0) works and removes the need for a background-color on the main-content 🥳 (also, position: relative and z-indexes on the wrappers are not needed anymore then)
