*Why moving elements with translate() is better than pos:abs top/left* Full post here: paulirish.com/2012/why-moving-elements-with-translate-is-better-than-posabs-topleft/ We dive into GPU accelerated layers, compositing, paint cost, DevTools' Timeline and "the dubstep effect". A must-see if you need high-fidelity animation on desktop and mobile.
Hey Paul, is there a chance of adding methods to HTMLElement for transforms? I'd imagine that doing transforms in a tight loop would be slowed down by the browser having to parse the string when you set it.
Over in the post's comment thread the CSSWG chair chimes in that APIs like that would indeed be very useful. Something like elem.style.CSSMatrix = ... or elem.style.transformObj.translateX += 10 somethingsomething..
This is great me and a co worker were just battling this out on which option was better and why. We realized the css is better but we didn't know why and this video explained it all!!! Thanks
Great in-depth comparison, Paul. Although the video framerate makes it impossible to spot the difference. The subpixel vs integer pixel tidbit is definitly one to keep in mind.
Thanks Paul. I'm very interested in learning more about CSS transforms, animations and cool parallax effects like on spokespedicabsdotcom and Ben the bodyguard, etc. Keep up the awesome vids!
Thanks you didn't say "subscribe".. bro. you deserve it. you won it.. you really didn't need to "Request" for a "subscription" ... Amazing information ..
here is a exmple .hero-col1 > div:first-child > article { left: 50%; margin: 0 auto; position: absolute; top: 50%; transform: translate(-50%, -50%); width: 80% where the article inside a div width of 60% and after 50% left the ariticle move over on its parent tag but after transfrom it position in middle
I have an old processor in my computer (Athlon from 2005). Yours translate-animation works better on my Firefox browser then on the Chrome. I also made a test with box-shadows and rotating and moving images, but that animation had a better performance in Chrome.
They both are CSS, just absolute position vs 3d translate. If your comparing moving stuff around with css to javascript your difference in performance should be way more significant.
I pretty much despise Google and hate Chrome. But it's for exactly reasons like this. So what we have a barely-perceptible stair stepping effect. Maybe we're not so devoid of contact with reality (like Mr. Irish and his bald-headed freakish friend) that we would worry about infinitesimally small issues as this. Honestly, I can't actually make out, in this video, the effect he's talking about, and in the demos I've seen it's just this side of perceptible when you look for it. But the real difference between the two was a scheme Google concocted to make old web apps less appealing. This scheme is just now coming to fruition in the introduction of interpolation-based "smoothing" of images moved, supposedly to improve performance. CSS transformed images, in contrast, are not smoothed as they move! It's a continuation of what we've been seeing more and more from Google (and it's copycat, Mozilla), which is the obsoletization of the web. This new "feature" is introducing artifacts into scripts that are like 10 years old. We see this at the same time wasteful gradient effects are being pushed into CSS. A cure for nothing... just the use of power to create more impetus for work correcting problems that should never have been introduced.
awesome stuff. imo the quick proof of this would have been to show the diff on mobile devices. TRBL is simply unusable while translate2d works like a charm even on old devices :)

You can actually hear his fans blowing because of the high CPU usage caused by the T/L animation. XD
Otherwise a very informative video. Thank you!

Amazing demo... I got to learn so many different things in these 13 minutes...

Thanks for teaching us Paul! And thanks to Chris Coyier too! I'm a big fan of both, thanks for your work.

Awesome explanation of the problem and tips on how to overcome it.
Cool tip. I already know where I can try this out in an existing project. Thanks!

here is a exmple
.hero-col1 > div:first-child > article {
left: 50%;
margin: 0 auto;
position: absolute;
top: 50%;
transform: translate(-50%, -50%);
width: 80%
where the article inside a div width of 60% and after 50% left the ariticle move over on its parent tag but after transfrom it position in middle

Oh wow, i'm def gonna start using this! I've been missing out!
Perfect explanation! Thank you

I could make out the effect he was talking about. Maybe your eyes put a sub-pixel blur on everything.
Amazing Demo!
that was great, as always
Great video! Really enjoyed it.
Cheers Paul
What about if I want to move an image that way? Is it better to use the translate() or will it be faster with background-position?
Great video. Thanks.
awesome video!
throw a translateZ(0) in there and your top/left stuff will execute on the gpu
You rock Paul, very interesting video :)
Helps a lot! thank you
this is really cool! I learned a bunched
