Kevin... for the past 2 years I've been watching you, you are still making me doubt my frontend skills and teaching me a whole new and awesome set of skills
Seems like every time I'm about to implement something, you come out with a video for almost exactly what I need and make my life a little bit easier. Thanks!
Love your channel. Using a bit of geometry you know that the corner will be sqrt(2) * --border-radius away from ur before elements center. Sqrt(2) is 1.414 so if you make your box shadow stroke (0.5 * --border-radius) you are guaranteed to fill the gap while basically minimizing the chance of overlapping other content on the page.
Hi there! As a trainer at a coding bootcamp, you so often already helped me give my students additional and deep informations on several topic just like Grid, Position etc. Now to give something back for all the times you helped me: I personally use a element instead of for my navigation lists, as per definition by MDN Web Docs I find it more fitting. In the end it may not really matter much, as the browser treats "menu" exactly the same as "ul" (giving it the exact same default stylings, too). However, it makes reading and understanding code just this tiny bit more comfortable in my opinion.
I was seriously looking for your video on using view-transitions when I got the email about the new vid and there is some gold in here about it too! Kismet!
Minor suggestions before the transitions. .nav-list li.active { background-color: transparent; ... } .nav-list li.active::before { ... } for the box-shadow make it based on your --border-radius and gap bewteen nav and main, maybe a min() between the two.
The more I watch your tutorials, the more I believe I am a frontend dev, really enjoy seeing code come to life! Thank you so much, you have helped me understand frontend so much over the two years I've been studying.
Iv been doing the same, but have you seen current job market? It will be miracle if you ever get hired and css skills are extremely unimportant as everyone just uses frameworks anyway. I'm not saying it to be ahole, I'm simply in same situation as you, over last 2 years front end pretty much died. Because of massive fang layoffs etc they can hire extremely skilled people as juniors.
Love these kind of videos, i gain so much new insight and it feels amazing. I do FE work but never the most intense design aspects of it so watching these is a great way to learn and improve.
Cool project! I think you could achieve the rounded corners effect semantically cleaner though by keeping the pseudo elements square and using a radial gradient as the background image. For the top one you would have the center of the gradient be in the top left corner, and add a transparent color stop at --border-radius, then another color stop also at --border-radius that has the body-bg color. :)
i wanted to write the same thing, it is in my opinion so much easier to do these with radial gradient trick, the only downside is possibly the additional step of adding the antialiasing by making the transition between transparent and solid color offset by like .3px but that's still super easy to implement. not even talking about the fact that he wouldn't have to use 2 pseudos, easily he could have done both corners with just one.
Hmm I'm curious what that radial gradient would look like using one pseudo element for both. I know UA-cam isn't ideal for posting code but if you see this I'd love to know what that radial-gradient value would look like.
@@clevermissfoxnot sure what they had in mind but you can layer multiple radial gradients into one background so if you just had the pseudo element be big enough you could place both gradients inside it. That's what I think it would be
would like to see your thoughts on how to tackle a dynamic mega menu. Meaning, showing a simple drop down, but then show a larger mega menu if the list has more than one nested nav automatically
You could probably do this with an SVG and a mask, or maybe a clip-path, and you'd have that, but then the positioning of it relies on JS. That's fine if it's what you need, but I'd rather fake it and keep the functionality simpler if I can :)
@@KevinPowell Thank you for answering! Did not expect that. Love your content and don't think that there is anybody coming close to the quality of your HTML\CSS content in my native language. Especially when it comes to accessibility.
amazing content and presentation, you made css very easy for me to the point that i really don't understand peoples frustration with it. And since i am kinda new to webdev, i really don't see why one would go with a framework instead of modern vanilla css (for personal and small scale projects obviously)
Cool video Kevin! It shows some ideas behind making the curved navigation menu. For the animation to work without enabling the experimental feature you can use css sibling selector. Also, if you want to support all types of background, from gradients to images, use SVG shapes instead of box shadow.
Hey our magician-alchemist, thank you, man. May all the Gods from the seven kingdom and beyond be on your side. Regarding the view-transition API, today there is no such on Canary 131.0.6732.1. But it's here in the regular Chrome version 129.0.6668.59.
Hi Kevin, nice video as always. Next tricky step : use an image or a gradient under the sidebar and active section transparent. I had to do it for a client it's a bit more complex but fun to do. I'm curious to see your solution. And if the client wants the transition for all brothers, it can be done in ajax but it's much more complicated to do 😅
Genuis method to achive the task ... Great, 3 months ago i had to do the same design of this nav it took me 3 hours to find a way but it was complicated than yours, but the one you made is a lot easier and straight forwards. ended up with me designing these curves on a figma and exported it as svg stick it with img tag with absolute position 😂😂 much easier and more simple
Looks great! Althought I might have put all the paddings (not the margins though) on the a, rather than the li, so that you can hover over the entire area and have the link respond to clicks
I really enjoy listening to you, Kevin, and watching your videos. You have such an easy manner about yourself. The time just flies by because we enjoy it so much. And you’re a great teacher as well. Keep up the good work.
This convex border radius won’t work if you have a dynamic background. It will work in carefully controlled settings but it’s not robust. I’m working on a library that does let you put inverted rounded corners on elements where they overlap or are contiguous by drawing SVG paths underneath them. It’s fast enough to run on every frame during animations which looks pretty cool. I clicked the thumbnail *because* it has a background image behind the inverted corners. I hoped you had found a better way than I.
That's an interesting solution. I always did this kind of stuff with square pseudoelements with radial gradient in the background, centered in one of the corners. I'm sure you know this method, but I'm curious why you didn't do that one. Are there any downsides to it, that I don't know about? 😃
Oooh, I remember when I was a young developer, we had an application with that kind of rounded borders. We implemented it with a bunch of and semi transparent gif images. 😂 Of course, that was 20 years ago.
awesome video as always! thank you! question: couldn't you have have just used '.nav-list li.active a' as the selector instead of the nth-child route? it would still only be selecting one element, right ?
Hi Kevin you know how to take css to the max and tour suggestions / lessons create a good basis. However, as a programmer (JS only) I wonder if you are not adevertising CSS as a "new" programming language - once just for layout - now a battle with lots of tips and tricks, speedy - variable declarations all over. In many of the comments I read respect for your knowledge but also the question to go back to the (your) basics -CSS only. I am one of them. Still learning, Benny
Love your videos, keeps me humble :) I watched your video on dvh, svh and was thinking why not use them... Then poof, you mentioned one might want to use them, Could be wrong but per your comments seems best to only use svh always?
@@KevinPowell Thanks been too long for more CSS battles, need to keep Kyle from Web Dev Simplified in his place. All in fun :) Not that i'm trying to start a fight...
Ho Kevin, very nice and interesting video. For pseudo elements I think that you could also use bottom 100% for the before and top 100% fpr the after. You should obtain the same result without using calc and variables. Any particulary reason that you use the calc? Cheers
Yeah my thoughts exactly. Would make the code simpler because there is no need for these variables then. That's magic of programming, things can be done in multiple ways.
Setting an exact pixel width for the shadow seems like it won't work for high font sizes, because the radius will grow but the shadow won't. I think you need a shadow width of at least (√2-1) * border-width to cover the corner.
We could do that! Or well, sort of, we have sqrt() in CSS now, but it's only in Firefox and Safari, waiting on Chrome still. (EDIT: could probably use a calc and base it off the border-radius size as well, be a bit less precise, but I think would get the job done for most situations)
What will happen to the nav if i need to scroll down ? Will it always be visible ? I tried to test it but It doesn't work with what i cloned from the github repository. I really learn a lot with your videos thank you very much !
to position the corners could we, for example, place the top corner at the bottom and give it a bottom of 100%. ive done that in the past and it seems to work but i’m wondering if it ever causes issues. is the method you used more accurate for any reason?
@@KevinPowell Negative value itself is not an issue, but you needed to introduce variable to specify the offest, when with 100% you don't need it. Also using transparent for preudos' background makes you solution compatible with non-solid backugound under the elements (I expected it not to work, but it does). I uploaded video with some modifications to my channel with codepen in its description - I think it may be interesting for you.
Kevin thanks for shearing your experience its really helpful for us but now i want some ting mindblowing like animation and hover effect please solve this problem please make some thing on hover and animation best wishes from pakistan
Wouldn't it be better if the ::after was a rotated version of ::before? Write the logic for the shadow and rounding for ::before and have the same for ::after but just rotate it to flip upside down?
Can you please do it with glassmorphism? I tried to do it on my mobile bottom nav bar but it gets tricky when dealing with transparency and borders as the links between the main element and the reverse borders are hard to smooth out. It looked impossible to do but I wonder if anyone could give it a try.
I always wanted to know how to make rounded corners in a logical way. I have seen some new properties added in css, but vscode tells me that they are not known. What should I do?
If VS Code doesn't like it, but it works in all the browsers, it doesn't really matter 😅. I'd just double check the browser support for what you're looking to use.
@@KevinPowellI found the solution. It is necessary that the Experimental Web Platform features in chrome://flags/ be activated. You are doing a great job. I learned a lot from you. Much respect!

😂😂😂 same here as a beginner

Minor suggestions before the transitions.
.nav-list li.active { background-color: transparent; ... }
.nav-list li.active::before { ... } for the box-shadow make it based on your --border-radius and gap bewteen nav and main, maybe a min() between the two.
For the box-shadow, that would work great. Not sure why you suggest the transparent background though? It would just be white then 🤔
My bad did not try it, could not inherant or initial work then?

Great video as usual. I've always wanted to do a star trek "LCARS" type of nav bar and with some css adjustments this would work great.
Pretty straight forward. Lovely tutorial. Keep up the good work, we support you. 👍

thank you for an idea!
Thank you Kevin for these super helpful videos!! Didn't know about the view-transition meta tag.

Man, you are such a wizard! The vid gave me a brain freeze but I still love it.
That’s wonderful! I always wondered how the outer round could be achieved
Quick tip, instead of doing body min-height: 100vh, i found that it's usually less problematic to do body and html height: 100%
Instead of using calc for the top/bottom, set them to 100%. You'll get the same effect with less setup.
You teach me something new everytime I watch your videos. Thank you so much 🎉
One second in the video, really nice content! I was wondering about those outward curves.
Oh my favourite layout, navigation on side panel. Combine it with neumorphism and it will be my wet dream.

I still didn't get how link gets active after its been clicked. Can anyone enlighten me?
The link is actually an href link to another html file (jome.html, about.html, ...), in that file, the link corresponded has the "active" class
Wouldn't it be better if the ::after was a rotated version of ::before? Write the logic for the shadow and rounding for ::before and have the same for ::after but just rotate it to flip upside down?
I can't find View Transition on Microsoft Edge flags😢 is it because it's not supported yet or something else?
