10 CSS animation tips and tricks

[@DampeS8N]

An animation technique I don't often see is what I call The Poof. Very simple: transition to a big-ass blur, opacity to 0 and scale up. Add in a skew and a translation in a direction for extra flair. Looks like the element disappears in a puff of smoke. I'm sure you can think of situations where this would be appropriate and satisfying. The reverse is also pretty impressive.

I love mixing in a transformY with this as well! Looks super clean & physical.

A codepen would be very nice :D

8:30 If you want this in CSS, there's another solution as well. We can use custom properties to achieve the same result: ```html ``` ```css .dot { animation-delay: calc(50ms * var(--i)); } ``` Basically, you don't declare custom properties in CSS, but rather in HTML with "indexing". Also, less code in your CSS. 🙂

OnlineTutorials taught me this and I love this trick

[@Cipscis]

Another animation/transtion trick I find really useful is that the visibility property can be animated. This can be useful for accessibility, since if you're doing something like animating an element's height to or from 0, you should be making it visibility hidden when it's collapsed so the user can't do stuff like tab into the hidden area with their keyboard focus. Because the visibility property has discrete values, they will flip at the midpoint of a transition or animation. But with animations you can "fix" this by putting two keyframes at the same point, so that midpoint is also at that point. But you can set up an animation with the same visibility value at 0% and 100%, so once the animation is over it will fall back to the value set directly on an element. That way, when you're hiding an element you can set its visibility to hidden, but give it a "stayVisible" animation to delay that value changing until your other animation or transition is complete. Of course this is all easy to do with JavaScript, but it's nice to know you can do it all right in your CSS instead.

Love it 🔥

[@gykonik]

Awesome information in that video! Maybe you could consider doing some sort of series "How CSS works under the hood"? In previous videos ,ou mentioned some things like "CSS parses the selectors from right to left" and stuff that I didn't know before. Moreover, I think many of us have no clue how CSS really works, and just know how to use it. (And you could build upon that series by another series about optimization :D) Would love to see something like that! 😊

[@RichardOles]

Yes. Got my vote. I’m relatively new to all this, and I’m amazed at what css can do. But there are so many css properties that appear similar, it’s difficult to keep straight. Like justify-content Vs justify-items etc. things like that. I need to create or find a kind map of what properties go with what css rules etc. even my vernacular might need a tweak. Hope I’m clear.

As someone who comes from the native mobile world its always mind blowing how simple and elegant the web animation API is.

[@iranmine123]

I really love the property idea, thats so nice like we can do lot of things with that, especially the gradient one Hope it gets added in all browsers

[@canarymultimedia]

Didn't know about prefers-reduced-motion and that it even is important for (simple) smooth scrolling, very interesting

[@wlockuz4467]

19:08 Mind blown, this is a game changer!

[@kohelet910]

I didn't know all of the tips you gave us :) ! Thanks 😀 I really like when you give tips and informations about accessibility.

[@rickardelimaa]

19:05 - this can also be achieved by animating the background position, having the gradient be 200% of the button width (going from red to blue back to red again) and then translate it's position -100%.

[@KevinPowell]

Yup, I noticed when editing that it wasn't the best example, lol. But we can animate the colors to anything, change the angle of the gradient... it opens up so many doors (and of course, not only for gradients!)

[@rickardelimaa]

@@KevinPowell Yeah, I'm looking forward to the day when properties are fully supported.

[@sixerd2236]

Hey some minor feedback on your audio. You should throw your audio into an EQ plugin or app and tune down the lower frequencies a bit. The bass is a little loud so when turning up the volume to hear you better my system is punching a little hard for some vocals (which my system is equalized to produce music so it's pretty flat). Great video and good information!

[@KevinPowell]

Thanks for the feedback! Audio is a bit of a black art to me, but I can totally fix that :D (EDIT: might be a few weeks until you see a difference since many things are at a certain point in production already, but I'll make sure to adjust!)

[@jfftck]

I am looking forward to CSS counters supporting returning numerical values instead of strings so we can just incrementally add delay or have more complex list indentations where you can have a left margin that doesn’t indent and everything right of it does.

Awesome! it was very interesting stuffs! thanks for that!

[@fullstackprojects5615]

Hey Kevin, Thanks for this. I was wondering how is you button centered in page? I was thinking there will be some classes you might have attached to button I don't see anyone. Have you added flex to button's parent container and then justify content center and align items centre? Just curious

[@danko5678]

I didn't remember that I had animation turned off in the system, probably did it for optimization. I don't agree that this should affect the animations in the browser

[@richardmhain]

Nice animations for games :) I guess -100ms animation-delay is like when u click it, it's like clicking it 100ms ago. Dots looks behaving that way starting at the top already when u click given that -value. Makes sense - back, + forward. Good 2c no JS for many effects. Great animations treats demo, maybe useful on projects someday. Thanks for holy week CSS treat - Cheers!

[@sudoscientist255]

Hi Kevin, I've been doing a lot of reading into how to use custom @property . One thing I keep coming across that I'm not understanding is the use case for having an @property with `syntax: '

[@lessons3141]

This last tip about hovering gradient was amazing, is it crossbrowser solution?

[@KevinPowell]

Safari has just added support, but no idea on where Firefox is with this at the moment :\

[@itsfake8149]

Please cover the Gsap Library is possible, it will be very useful.

[@timgrei1730]

You could do the n-th child delay in vanilla CSS with counters, right?

[@sreeharipv486]

Can we register custom properties in vanilla css by using @property method ??

[@jfftck]

The problem with Houdini is none of the specifications are past draft stage and that can result in many issues in the future, that is why Mozilla doesn’t support it.

[@KevinPowell]

Mozilla doesn't support it because their team was gutted and they have a much smaller budget than in the past. Chrome 100% was a bit too early on putting into production imo, but now with Safari getting behind @property as well, it is what it is at this point

Are you human? AWESOME! 😁

[@samarthnagar1516]

do you use tailwind what are your views on it

[@HaiNguyen-zd6yj]

Hi sir, is there any solution for animation-delay not working with animation-timeline:view() ? Thank you!

[@KevinPowell]

Don't think you can delay, when it's scroll based, you'll just want to change the offsets for the view()

[@khumbomunsaka]

The links aren’t in the description. I don’t know if I am the only one that sees that.

Oops! Sorry about that, I've just added them :)

Another great video, as usual, and I'm glad I had a small part in it. ☺ These are some great tips, and if anyone wants to go a little deeper into the negative delay thing, I have a part in one of my lectures where I tried to explain it in a more visual way.
