Continuing in this series on how we can use the Intersection Observer API, here is a look at how we can use it to detect the position of elements on our page and set up a simple JavaScript function to have them fade and slide into view as the person scrolls down the page, I hope you enjoy it :)

Hey there Kevin, Mate, you are the best teacher ever. To be honest, I do not have education in IT but now I am developing and designing web. It came possible due to youtube tutorials. But since I came across your channel., I only now refer to your tutorials. I never knew before how much CSS have potential. Keep up the good work. Cheers mate.

This is a really useful video as i couldn't find anywhere how to use "slide in" effects with Grid. transform: translateX(-50%); did the trick! i was pulling my hair out trying to use negative margins.

@antoninoadornetto6958 2 года назад

THANK YOU!!!!

@motdde 3 года назад

Thanks, Kelvin, this is really cool. I'll assume the left and right content translating and changing opacity at different times is caused by the grids, right?

@devzorsmallz 2 года назад

I believe it's because the height of the paragraphs is less than the height of the images, so the images hit the rootMargin first. :)

Thank you so much, can you make a video on darkening the background image as you scroll

4 года назад

Great stuff Kevin, thanks a lot!! Would you mind sharing with us how should we tweak the code to make these transitions appear over and over without refreshing the page, as I saw you doing all along this episode?

@KevinPowell 4 года назад

I wouldn't really recommend that from a user experience point of view. If I was on a site and things kept fading in and out, it would drive me crazy. You could use the same idea to do the opposite though, but instead of when it's in page, do it when it leaves the page.

4 года назад

@@KevinPowell Thanks for your recommendation, I am with you in that animations shouldn't annoy the user. So I figured out that it's actually the normal behavior some of the websites I have checked. Animations are thrown at the first load of the page, then it stays fixed when you come back on them with the scroll. Thus making sense of the best practice we'r talking about ;)

@stephena8965 3 года назад

Hey Kev, great video, implemented this is minutes! Is it possible to add a custom variable like data-delay = -300px in the html and then use that in the rootMargin options (along with a default value)? Maybe my logic is off in how to achieve this, but I was just wondering to what extent I could customise the behaviour of the observer without creating millions of classes!

@aram5642 4 года назад

I love your final comment on not overusing the effect!

@SteveBonin 3 года назад

*** Beware of Sliding and fading *** Hi Kevin, I have been having a lot of fun following your videos over the past couple weeks... I just wanted to outline a problem I had and what the culprit was. I was using the intersection to fade-in and slide and could not figure out why some worked and fewer worked as I shrunk the screen. I set the initial translate at -200px, as it turns out this placed the div off the page and the intersection observer no longer sees the so it doesn't fire...ugh!!! Reducing the initial translate fixed the problem.

@SteveBonin 3 года назад

give each div a separate id and assign a different transition-delay to each id

@lenolands 3 года назад

awesome

@legostud 2 года назад

Fun trick. Set root margins of say -70% 0 -30% to create a thin line on the page for the observer to look at. Now with a threshold of 0 the intersection event will only occur at that point on the page.

@nkmicros540 3 года назад

Hi Nice tutorial, but I have a question: Please could you comment where exactly you implement that javascript in the main page, like in the head or on the bottom, if jquery.js is needed... if you could explain the main index.html page structure. I watched several your videos but nowhere you showing this. I don't quite want to deep dive in javascripts learning as I don't work on that area, I just want to implement this concept in my website, where I have problem with my multiple images, it caching the browser much and takes quite long to load the page. thanks

@RobertGuttersohn 4 года назад

Hi Kevin. I am new to javascript. How were you able to get the sliders to animate without telling the intersection observer what class to add?

@KevinPowell 4 года назад

I do tell it, at around 6:34 Later on when I tell it to observe, if it sees it, it'll run that function above and add the class :)

Hi there Kevin, and thanks a lot for this. How could I improve the loading smoothness? They items appear, the scrolling stops for 1 second, and then I can scroll again.

just dont unset the observer and if isIntersecting is false u remove the class fadein (with elt.classList.remove('.myclass') so the animation will do reverse from 1 opacity to 0 when they go outscreen

@omar99ize 5 лет назад

Hey Kevin! A great video as always! I wanted to share that I just finished my own library a few days ago called scroll-dom-animation for this purpose and for future projects of mine. I created this library to make my animations very simple and all in one spot plus making it declarative so I know what is going on in just a glance. It also doesn't require any modification to your css like hiding the element before animation because the library takes care of initializing the css, so it works very well with bootstrap and other css libraries and also with existing projects. The way it works is you would just need to provide the element selector and the symbol for the direction such as '->' for to-right direction or '*' for fade-in. You can also provide an extra options object for customizing speed/offset/inviewdistance/etc. Check it out on github/npm and check the demo and please feel free to give me your feedback! Thanks link: www.npmjs.com/package/scroll-dom-animation

@KevinPowell 5 лет назад
