Create an animated, glowing, gradient border with CSS
HTML-код
- Опубликовано: 24 июл 2024
- Inspired by a codepen by Gayane Gasparyan - codepen.io/gayane-gasparyan/p... - I took my own attempt to create a rotating gradient border, including a nice soft glow.
To do it, I use @property, which doesn't have fantastic browser support, but near the end of the video I look at why that's not really a big deal 🙂

Kevin,
This is such a nice format for tutorial. You clearly explained step by step how this works. Thank you
Mind-blown! Thanks, Kelv!
This might just be my favorite CSS Video of all time
I just discovered this! Thank you Kevin for making this tutorial!
A lot of people were asking for a tutorial, so I would like to put your video inside the pen, if you don't mind
Ok, I'm baffled. That's really good work!
You have made CSS truly fun and understandable, thanks.
Also made me want to get back into working as a programmer, but only in UI/Css stuff =D
@@SCHTRAM To dare is to do 😄, just do it, fr.
Súper !! More videos like this please!! Thankyou!
Trully Amazing . I love you !
Kevinn, I loved this video friend! 🤩
What a gorgeous effect
Totally gonna use this idea!
As always really helpfull :) I will use it in my projects thanks to you!
This is so freaking COOL!
Great video! Would love to see more tutorials and/or examples of practical, forward progressive applications of @property.
thanks Kevin, always great
I am learning a lot through your video thankuu
Wow! Super Awesome!
Whenever i watch your video i literally think that why are your videos soo much related to the my problem you are video are very good and the knowledge you provide is literally the nest level thankyou you for providing the knowledge by the way i am from Indian and know ..
You are the best. Good luck ❤
Thank you! Great video!
Beautiful!
you are always awesome for CSS!!!!!!
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.
Amazinggggg
Thanks Kevin for these fun tutorials. One question I have however is that with majority of traffic coming from mobile devices how can we translate some of these effects to touch based (micro)interactions?
I barely know your channel and already benefiting from your videos...
I copied your Cool 3d card that follows the mouse movement using JavaScript as part of my training abd learned so much advanced css coding and tricks
Just want to say thank you for your enormous efforts and knowledge that ur sharing with us (beginners&students)
May allah bless you 😘
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! Watching your videos has reignited my interest in front-end developement.
Thank you!!! saw something like this a couple of days ago and was going message you to see if you could do a video on it :)
thank you sooo much kevin
this is so cool thank u
amazing content
That was so fun.
Thank You🔥🔥🔥
Thanx you sir 👍
Thank you for your videos, i started learning code half a year ago and many of your videos taught me alot
Thank you so much!
more effects and cool animations, please
I love your videos in which you sometimes mistype and ponder. I would like to see more of them again. But maybe that's because I don't belong to the TikTok generation and like to watch you make mistakes. In any case, keep going somehow! Your videos are perfect! A big thank you to you!
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 ?
Hey Kevin, great video. Why aren't you going with the unit dvh instead of vh. Just to keep it right and think at the mobiles devices out there. Apart from that, all good as usual.
Because of you I dont hate front end as much.
once i resolved this making exact the same, but without that property. instead a got 2 div one smaller than the other and the bigger rotating, filled with the colors
very cool! Hi sir Kevin, I wonder if you are planning to release another chatgpt content especially after the gpt4 announcement? cheers! 😊
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?
does "place-items" not have suggestion "center" for you guys too in VS Code?
Thankyou
Thanks, maybe this helps. I've seen a codepen of this but it didn't work in my html file for some reason. Didn't even move
Noice
I like these shorter style video's where you don't type, but paste! Good job 👍
So great ! How to make it animated only when appear in the screen.
Hi, great video, is it possible to have a solid border, only animate on hover? Thank you
In mob&desk app development, of course we need to design the content (background-colors, colors, positions, etc.), So will I need css
Having trouble getting the gradient to render after swapping out the discrete degree value with the @property value. Anyone know why this may be?
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?
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.
Since when did the body start to stretch to the full height of the viewport? It used to be that the html was the full height, and the body was only only as tall as required
Do all major evergreen browsers support this houdini feature?
That's smart solution! however, However, is there a solution that works across all modern browsers? Tried the link, doesn't work on safari, the border doesn't show at all, let alone the animation
You're doing great!
Thank you!
Is there anyway of making the border longer just soley verticly as it doesnt span all my text ;-;
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
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.
@@KevinPowell padding with background-clip works great
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
Which video is this if you dont mind me asking? Im looking for the exact same thing :O
@@Jakiita1 its this one ruclips.net/video/fcnDBP3k3BE/видео.html
Hi, very cool video ! I don't know why when I put a hover transform on the card by following your steps, the pseudoelements go over my card an hide it... I've tried to play with the z-index of the parent but it don't seems to work neither. If someone has any solutions 👌
what i found as a solution is that the background-color of the container of .card should have an alpha component closer to zero. this solved it for me.
can we make this only while hovering if yes can any one tell me how
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
It is possible to fallback to animate the gradient with javascript when @property is not supported?
There might even be a polyfill, I haven't looked into it though
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.
any solution to this ?
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;
I think masking might create a more performant version of this. I’ll post a link if I figure it out.
Sir, I have learnt javascript but the problem is, I don't know where to add javascript on my projects.
Please help
the gradient doesn't work in firefox at all - seems like you should first put the gradient value in root as fallback and put houdini property after root
You don’t tell us but is the gradient angle not normally animatable?
Is it necessary to use both ::before and ::after?
one is blur that give effect of light/shadow and the other is moving solid colors
Hi, im using Styled components and i cant find solution for this part
@property --rotate {
syntax: "";
initial-value: 132deg;
inherits: false;
}
@keyframes spin {
0% {
--rotate: 0deg;
}
100% {
--rotate: 360deg;
}
}
I also asked chatGPT V4 without positive result :/ Does any1 knows please?
Does not work with Firefox unfortunately, unless you remove the property from the gradient
that's exactly the problem I ran into, it's so sad.
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.
nice I just think that colors pick is not optimal for that kind of effect
When I'm adding inset: -.5rem and z-index: -1, im loosing the glow effect and an opaque box is coming, can anyone help me out with that?
any solution?
what i found as a solution is that the background-color of the container of .card should have an alpha component closer to zero. this solved it for me.
Brilliant!!!
But Hoodiny is "under construction" for the last 5 years as I remember, or even more. But anyway, it will work without animation. Very good example of graceful degradation.
Thank you!
Could someone help me? I want to put this code at Firefox
For now, no way, it's not supported as I did it here.
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...
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.
But you still can animate your css var with js
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;
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
Thanks friend, you are a genius, before it didn't work on Chrome and also on Firefox. You saved me, very beautiful effect.
this is one of those "you like it, but it's bad UX so nevermind"
whos the best ha, whos the best - ps. stewie
its good but its so complex
Present sir
Pretty sure this was inspired by new starter template of Next.js
Never even looked at it yet!
I used Bing AI to summarize Houdini CSS. Soon you will be summarized too. I should have pasted your transcript. There will likely be an app to turn any video into a AI RUclips Short.
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.
for rotating, why did you use houdini instead of just plain ol' rotate: ;
nevermind, i might have misunerstood the assignment
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
@@KevinPowell yeah, i misunerstood what you wanted to rotate. Love your videos!
Kevin, STOPPP.. I was literally looking at Codepens of this! Go to the restroom and see the notification for this video.. SMH spy on cooler people man 😂
OK, now here's the question: add any `animation` to the .card and explain why it breaks...
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.
Hi sir i have a request for you. There are many people like me who are not native english speakers. It is difficult to understand when you speak fast. If you could speak slower then we can have better understanding
This is me talking slower 😂. I really do try. You could show the video down a bit in the video settings
@@KevinPowell don't do it Kevin, you don't speak fast at all.

it dont look anything like what u demoed to start with i got a codepen about cards!
What doesn't look the same? My Codepen goes to my finished code, and I think it's closer to the initial one, just with different colors and a slower animation 🤔
