Create a clean, modern navigation with HTML & CSS

[@jimhillr]

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.

[@jameskamau1326]

I can't believe you solved an issue that took me 3 weeks to solve in just 15 minutes. This is amazing thanks

[@GetPsyched6]

Kevin, i just wanted to say, you're a really nice person and you make the world a better place. Thanks for all the amazing content you give us.

[@KevinPowell]

I appreciate that, thanks so much!

[@AlexCouch65]

Not gonna lie but i was expecting a "...but" in here

[@beardedraider4751]

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.

[@wykydytron]

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.

[@tspander]

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. :)

[@Cuwubiq]

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.

[@clevermissfox]

Hmm I'm curious what that radial gradient would look like using one pseudo element for both. I know KZbin isn't ideal for posting code but if you see this I'd love to know what that radial-gradient value would look like.

[@clevermissfox]

@@Cuwubiq wait cubiq I think I know you from discord! I'll ask you there!

[@tspander]

@@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

[@knolljo]

Your css intuition is so good, thats probably the result of years of building stuff with it

[@deatho0ne587]

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.

[@KevinPowell]

For the box-shadow, that would work great. Not sure why you suggest the transparent background though? It would just be white then 🤔

[@deatho0ne587]

My bad did not try it, could not inherant or initial work then?

[@wchorski]

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

[@TomWien]

Thank you, Sir!!! Thank you for your content and especially this one. I tried so hard to get a responsive one, with grid, flex .... Thank you

[@edwardhandrich6043]

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.

[@gbbarn]

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

[@KevinPowell]

Thanks so much!

[@uahnbu]

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.

[@donniedamato]

Instead of using calc for the top/bottom, set them to 100%. You'll get the same effect with less setup.

[@l-cornelius-dol]

Fascinating. How I wish CSS was internally consistent and coherent, so I didn't have to memorize a huge ball of esoteric once-off's.

[@TheodorSirmanoff]

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.

[@EricFressange]

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 😅

[@KevinPowell]

Yeah I went the easy route here with a solid background 😅

[@andrewrea2799]

That was way cool Kevin.

[@brianjett1446]

Can you please answer my question, do you have a video about how to make a responsible drop-down menu???

[@mswalsh68]

⁠would the transition work in react? Since you’re not actually changing pages per se… you’re just re-rendering components on the page.

[@patrick_foley]

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?

[@hookenz]

Awesome content. Personally I prefer quite fast animation. Slow animation is .... well it slows you down and gets tiresome to look at.

[@joyvideos1802]

Good Content, Thanks Kevin

[@aklikes]

Any design thoughts on how to handle this in responsive.

[@KevinPowell]

I'd just have it collapse sideways with a hamburger to "open" it probably. You can animate grid template columns, though in this case, it might be best not to do that, since the content on the other side would get repainted as well. Might be worth going with a more fixed approach, and having to add padding or margin to make sure content doesn't go under it.

[@MRN1ch0l45]

thats a cool Watermelon

[@blagojamojsoski5166]

Amazing! do you have an example how to do it responsive with hamburger menu? tnx

[@Kr0s0n]

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 !

[@sknEK_code_chef]

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 ?

[@Dexter101x]

[@ravidubey6817]

I dont know how to use n-th child , but I think it can be achived with n-th child the active tab needs to get its previous and next element and just just border top end radius and border bottom end radius!? May be it can work !? Please let me know if it can be ? As you are master in CSS so you can easily tell me if its possible. Thank you.

[@riccardopavesi9324]

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

[@rand0mtv660]

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.

[@bradeagle7297]

why not use border solid instead of box shadow?

[@МихайлоХодак-й7ъ]

Cool. But what if one of the backgrounds is transparent?

[@hristoistoyanov]

Thanks Kevin, are there any responsive considerations?

[@saeruji]

New viewer here, so don't know if you addressed it on later videos, but apparently they now changed it, and now instead of the meta tag, you put @view-transition {navigation: auto;} in your css

[@lukemartinau]

In the ::before instead of the ‘top: calc()’ why not just say ‘bottom: 100%;’?

[@justinernest2363]

how do you get your browser to update as you write your code?

If something is lower down on the page, there might be an argument for dvh. The problem still it that it can cause reflows though.

[@othmanosx]

Can you please do it with glassmorphism?

It looked impossible to do but I wonder if anyone could give it a try.

[@AlphaPlus9]

I tried to do this, but either I did something wrong or it's very buggy and does not seem to work very well. The transition is working like every other time. I think I'll stick with non-experimental stuff ;)

Don't use negative top, use bottom: 100% instead.

[@KevinPowell]

That works too, but I don't see any issue with using a negative here?

[@QwDragon]

@@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.

[@orlandoferazzani3639]

video is amazing. Really helped my uni project but i am encountering a strange problem. My navbar is for my profile page and has ofc some elements but they toggle between fieldsets with js. With said script, i add/remove the class actvie bur for some reason, the trasition isnt applied. I can see the transition is being registered by the browser because if i refresh the page, i can see the "switching animation" from the tab i am to the defaul active tab, which is the first nav element.

[@gamertag8721]

I do have a serious question, why is this design making its rounds these days --- I see a lot of pens with the "modern" menu floating around -- a lot of variations, some even have true transparency, and are not faked out with the background color. I even forked a pen to add transitions to the first one I ran across this design (went and checked it was in mid-2021), I remember menus like this in the early 2000s So why is this design suddenly so popular.

[@wykydytron]

In current job market it seems like being front end KZbinr is only way to have job in front end. 2023 in my country we had over 200 job openings for actual juniors any given time. Today we had 6 opening and all 6 required "juniors" to have several years of experience and to be fluent in several languages, bare minimum was Js, react,angular, next, express and several other more specific by company. It's absurd. I no longer feel like front end is job worthy anymore.

I do provide the finished code, and I did look at all the code to do it. I didn't write the HTML on screen, but I showed the parts you need. It's the same pattern you'd find for any navigation (nav, with a list inside, with the links in the list items) which is why I went a bit fast over that part to get into the styling of it.

[@Human_Evolution-]

Love this channel but side navs are lame!

[@PaulAllsopp-rh5gb]

Hmm. I was really liking this until you defined a custom property inside one selector and then used it inside another. From a JS perspective that would be like breaking scope. You're adding it inside a block, but it's become global. Yuk! Still, I'll keep watching because I do like the end result.

[@PaulAllsopp-rh5gb]

Hmm, so I just found this through JS: document.documentElement.style.setProperty('--document-height', `${some_variable}px`); So, when defining custom properties, are they scoped to the document? More investigation.

[@owlmostdead9492]
