Parallax effects can be cool, but I’m always told the CSS-only solutions aren’t “true” parallax. Well, thanks to scroll-timeline: scroll(), we can now create true parallax effects without one line of JS and have complete control over the speed of each layer.

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 🙂

@z3rocodes 6 месяцев назад

Firefox is slacking.. They still don't have the view transitions or navigation API available after a year either :(

@KevinPowell 6 месяцев назад

@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 6 месяцев назад

@@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.

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

@christianlorenz1696 6 месяцев назад

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.

@nomadshiba 6 месяцев назад

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 6 месяцев назад

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.

@Wolfeur 6 месяцев назад

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

@gE0013 6 месяцев назад

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!

@tonyblox Месяц назад

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

@krzysztofprzygoda7635 6 месяцев назад

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

@TAHppled 6 месяцев назад

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.

@AjajRajguruAJ 6 месяцев назад

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!

@bramus 6 месяцев назад

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.

@norboost 6 месяцев назад

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

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 6 месяцев назад

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.

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 6 месяцев назад

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)
