I just went down the rotating gradient rabbit hole like a month ago. When I saw your title and thumbnail, I was scared you were going to show something I missed 😅. But I got to the angle property point and decided to go in a different direction because of browser support. Keep up the good work!

I think even in a square box the gradient rotation would have looked slightly off - to have a constant apparent speed along the outline, you'd probably need a circle.

Good job Kevin. But could you do it with transparent (card) background? 🤔I bet it would look awesome in glassmorphism, but I was not able to figure it out. EDIT: Never mind, YT just redirected me to your other vieo, where you made glowing border with SVG, so it can be done that way. Its funny, you answered my question, even before I managed to ask it :D

I was working with some after & before but the inset wasn't working and had to do width 100% & top 0 bottom 0, any idea? using beta chrome on Linux

was it position relative, and not absolute? Only thing I can think of.

[@io1921]

[@ernststa]

Does not work with Firefox unfortunately, unless you remove the property from the gradient

[@issy63ls]

Same here, i'm stuck on same problem.. how did you fix it?

@@issy63ls I think there are 2 fixes, first is to write browser specific code second is to use javascript for the rotating effect of the gradient.

[@nomadshiba]

wonder if we can use border: solid .5rem transparent didnt try tho, so the space there is actually be a "border" tho there is probably background behind the border so wouldnt work wonder if we can make the background start after the border-box

[@KevinPowell]

Oh, that's a good suggestion! Sadly, what happens is the background of the element actually gets drawn under the border. There are ways around that with `background-clip`, but then you lose the border-radius. I think the best solution is probably a --padding custom property on the parent, and use that for the inset value.

[@nomadshiba]

@@KevinPowell padding with background-clip works great

great vid, but do you think Lottie animation would have done better here ? if we had 100 of these, i think it'd be better to switch to lottie rather than rendering css

[@mikemaccana]

You don’t tell us but is the gradient angle not normally animatable?

[@ember2081]

Is it necessary to use both ::before and ::after?

[@naczelnypsycholog6296]

one is blur that give effect of light/shadow and the other is moving solid colors

[@fabian3411]

Great Video! I tried in my project and I find this solution works really well for me, there’s one weird thing though: whenever I use any kind of transform: translate property on the div that has the pseudo elements, the inset one them breaks and the pseudo elements appear in front of the div again, though strangely any text stays visible. The fix I came up with is wrapping the div inside another wrapper, so I don’t have to use any translate properties (I have to use them) on the element itself but only on its wrapper. Is there an explanation to this seemingly strange behavior?

[@TheTrentmoller]

So great ! How to make it animated only when appear in the screen.

[@josephnwachukwu5775]

do you think its possible to do this on an input element

[@Mattylarochelle]

Hey Kevin, I really appreciate your videos. I'm having a problem at 2:57 the blur function does not create a shadow around the card but instead it stays contained within the card... Any ideas why that might be happening?

[@appsenence9244]

Make sure you plar around with the numbers of the size of your container and the blur effect. It doesn't quite work as you would expect it to.

[@Alexandra-Rex]

I've had something like this, trying to make the center transparent, or to actually have a semi transparent background. Like an RGB animation around a somewhat transparent "screen" where text can be. I've been trying to use it as an alert overlay for streams. Is it ok to play around with your way of doing it to see how it turns out for what I want?

Hello, It seems not working with bootstrap 5.

[@shayanzamani9907]

Thanks for your content. BTW, is there any way to have a box with animated, gradient border color when the box itself is half-transparent or maybe a glassmorphism effect ?

[@SvenThielen]

I found a neat trick to get another type of animation to work in firefox by pasting the code below just after the one described in the video: @-moz-document url-prefix() { .card::before, .card::after { background: linear-gradient( 45deg, var(--clr-5), var(--clr-4), var(--clr-6), var(--clr-7), var(--clr-5), var(--clr-4), var(--clr-6), var(--clr-7)); background-size: 450% 100%; animation: ffspin 3s linear infinite; } } @keyframes ffspin { 0% { background-position:0%; } 100% { background-position:96%; } } Colors I used: --clr-4: #2d8f85; --clr-5: #38CFD9; --clr-6: #637c54; --clr-7: #4e00c2;

[@luischiesa4568]

Hey man! I’m new coding and I’m not the best English speaker/reader could you help me to fix this problem with the Firefox I put that and still not working

[@NiltonOliv]

Thanks friend, you are a genius, before it didn't work on Chrome and also on Firefox. You saved me, very beautiful effect.

[@tzisorey]

Now you just need a script to make the gradient follow the direction that the mouse pointer is, and adjust the brightness based on the distance...

[@Disorrder]

But you still can animate your css var with js

[@colbycrawford7586]

Having trouble getting the gradient to render after swapping out the discrete degree value with the @property value. Anyone know why this may be?

[@CMB696]

I did something similar this a weak ago but it is a big headache 'cause .outer-card > . gradient-border > .main-card and for .outer-card:before for blur aah . And I saw that post few days ago and i thought that i can't , and u did it just with a .card 🤯 it's big brain time;

[@naczelnypsycholog6296]

nice I just think that colors pick is not optimal for that kind of effect

[@SvenThielen]

Why is Firefox so far behind on support of these cool features? Can only get it to work with a fallback color. The property does not work and animation neither.

can we make this only while hovering if yes can any one tell me how

for rotating, why did you use houdini instead of just plain ol' rotate: ;

[@palantonio8764]

nevermind, i might have misunerstood the assignment

[@KevinPowell]

I looked at what happened at around 3:10 if you tried a rotate, the entire element is rotating around. We need to animate either the angle itself inside the gradient (or you could animate the colors), and to do that we need to use houdini... unless I missed something obvious :D

[@palantonio8764]

@@KevinPowell yeah, i misunerstood what you wanted to rotate. Love your videos!

[@mykalimba]

It would be nice to speak to how much CPU (GPU?) it takes for modern browsers to manage some of these more advanced rendering features (blur filter, gradients). The last thing we need are uninformed web developers overusing techniques like these without awareness of how it can impact UX for those viewing websites overloaded with "features" like this. I've visited websites where a simple full screen background blur filter causes my laptop fan to spin up like crazy.

[@pdxpro7409]

its good but its so complex

[@scottmccauley7555]

OK, now here's the question: add any `animation` to the .card and explain why it breaks...

[@KevinPowell]

If you're animating, I'm guessing it's a transform? In that case, it's making a new stacking context, so the z-index: -1; on the pseudo-elements no longer goes behind the element.
