These mini videos are so informative yet so rare. Thank you for making these kinda videos. 🙏😊

[@shadyheadstash]

Thanks for this. I make a ton of "fullscreen" apps making GIS and weird art with three.js, so relevant to a lot of what I make.

maybe we should use dvh for mobile design because vh browser support rate is about 10% higher also vh works well on desktop. useful tutorial thank you.

[@snivels]

It makes me sad that we have to even take these things into consideration. That mobile browsers just disregard specifications entirely is crazy.

[@tusharbhojani2260]

Perfect solution, before it i was using the position fixed. I had wasted lots of time trying to find the perfect solution.

[@user-ie7md3mm6x]

I didn't knew that, impressive content man❤

[@jackn]

i think you almost always want to use `svh`.
on desktop browsers this will almost always be equivalent to `vh`.
on mobile, the problem with using `dvh` is that your components will constantly resize depending on if the address bar is present or not. the user almost always starts in small viewport mode anyway

[@gamevidzist]

Will this not cause layout shift when scrolling up? If so would you recommend trading off CLS score for accurate screens?

[@ianc6418]

great tips!

[@yt-sh]

good tip! thanks

[@victorc.chikezie]

Nice tutorial however, i noticed that dvh on fixed menu bar on mobile causes a little flicker when scrolled up. How do i fix that?

[@jatiquep5543]

Thank you sir. ❤❤❤

Thanks bro, from chile

I never knew about this. I’m learning about frontend development and always use 100vh or just vh/w where applicable.
I have a question before I transition. I see that it says devices on iOS before 15.4 aren’t supported. What will happen if I only specify say 100dvh - will it fallback to just 100vh?

[@itsgojoverfr]

if you are using custom css then you could basically do this
item {
height: 100vh;
height: 100dvh;
}
so that if dvh isn't supported it will just use the vh unit instead

I have a 1920 1080 p screen i downloaded a UA-cam tutorial about html css website and he assigned 150px size to h1 element which looks good on his screen but on my screen it was too big. So different screen resolutions can make an element look different even if the same px size is assigned to it??

[@ByteGrad]

Interesting, I think px should look the same

[@benderbendy]

Yes, a pixel can change between devices. Pixels are "relative" to screen density. 150px can look different in a low-density screen or high-density screen. The size of 150px don't change, but visually you see the difference because the density.

Great tip thanks!
Don't know if it's just me -- but your videos are always a little difficult to hear. Maybe consider boosting the volume a bit? Cheers :)

[@porcyc]

100% is the best solution

[@rmnbrtshk5945]

I had problems with animations which were bound to scroll position. When you scroll down and up (with "dvh") on a mobile device the height of the viewport changes and that causes scroll position measure changes. And my content was jumping

[@jaisuperawesome]

What do you use to create animation?

[@demarco6967]

great videoo!

[@coolemur976]

IE should be removed from caniuse.

[@thepetesmith]

The “stuff” is called browser chrome.
