How To Create An Image Slider In HTML, CSS & Javascript

[@akifahmed9610]

We need more such tutorials like these. Handling small projects without use of any library is such a great way to learn.

[@kevinariza603]

Hello people! Also, you can add another event listener to check if the screen size changes and update the size variable accordingly, so it becomes responsive. This is what I did: I Changed this: const size = carouselImages[0].clientWidth; By this: let size = carouselImages[0].clientWidth; And I added this to the script: window.addEventListener('resize', () => { carouselSlide.style.transition = "none"; size = carouselImages[0].clientWidth; carouselSlide.style.transform = 'translateX(' + (-size * counter) + 'px)'; }); Thanks for these tutorials, Ed, you are great!

[@ihatejart123]

unfortunately doesnt work for me :( Any idea or tips? is there a specific position within the script for the new eventlistener to place it in? help would be much appreciated :)

[@kevinariza603]

@@ihatejart123 Here is the source code, feel free to explore/fork/download it and use it to your own need: github.com/Kevwas/image-slider/ If you want something a bit more advanced, taste this other image-slider I made with Bootstrap: github.com/Kevwas/image-slider-2/ Here there is another good example: w3schools.com/howto/howto_js_slideshow.asp

Works well, unless you use a page that's not full screen or resize the page during use, can you explain how to make it mobile/resize friendly?

For responsiveness don't use the JS solutions posted below, just use this simple css: .carousel-container { width: 60%; margin: auto; overflow: hidden; } .carousel-slide { display: flex; aspect-ratio: 2 / 1; /*

my problem is this Cannot read property 'id' of undefined. at this line if (carouselImages[counter].id === 'lastClone') { please help me

[@chrisj.2611]

Yap, same here.

[@chrisj.2611]

I dont know why but after I used this part (found it way below in the comments) and just renamed the variable names (b/c i gave it different ones) it worked for me: carouselSlide.addEventListener('transitionend', () => { if(carouselImages[counter].id === 'lastClone') { carouselSlide.style.transition = "none"; counter = carouselImages.length - 2; carouselSlide.style.transform = 'translateX(' + (-size * counter) + 'px)'; } else if(carouselImages[counter].id === 'firstClone') { carouselSlide.style.transition = "none"; counter = carouselImages.length - counter; carouselSlide.style.transform = 'translateX(' + (-size * counter) + 'px)'; } });

[@codenamegrant]

8:46; I found that making changes to the code and refreshing the page responds with the incorrect clientWidth, and so my slider remains on the lastClone image. I dont know why this happens, but to fix it, I have to use Ctrl+F5 to refresh the page instead of a normal refresh/reload.

[@mayankkumar1417]

It also happening with me , did you solve the problem now?

[@mayankkumar1417]

I think the first carouselSlide.style.transform = 'translateX(' + (-size * counter) + 'px)'; is not working everytime.

[@AJ-Pixelyze]

Good tutorial, my question is, why clone when you could have reset how you access to display the element would the "transitionend" event still work? I built a slider but everytime I press on the next or prev to reset the position it automatically slides to that original element and not doing what your slider does.

[@EffuseDex]

Loved this, super helpful!

Im confused with the first clone and last clone. I have the transition but but the first image doesnt transition back to the last image. It just keeps going till i run out of images

[@gmanpublications]

Hi, I am following along with the video and I noticed a couple of things. First is that there is more than one image instead of only showing one at a time. The second is when I ran the following code... carouselSlide.addEventListener('transitionend', () =>{ console.log('Fired'); }); No fired doesn't show up when I click next.

[@MuhammadShahbaz-fg4jh]

For one image at a time, check your css, in parent container, use overflow:hidden

[@IstvanWeisz_logoby]

greatest slider video that I see!!!! Thanks Ed!!!!!

[@kevinsing8948]

the code is messed up the moment you add carouselSlide.style.transform= 'translateX(' + (-size*counter)+ 'px)' the following happens : scroll with mouse to zoom in and out and you will see multiple images within the frame(60% width border). images dont fit border, only works with 100% zoom, change the zoom and enjoy your headache.

[@tadas4785]

It happens because size property is set upon page load. It is constant and doesn't change if you zoom or resize window. You can zoom page and then refresh, after that it should work fine. In fact this carousel is responsive, because it is not so common to change window size during use-time. If you want to make it 100% clean, just add an event, which would change 'size' property if page is resized. Like this: window.onresize = () => { size = carouselImages[0].clientWidth; carouselSlide.style.transition = "none"; carouselSlide.style.transform = "translateX(" + -size * counter + "px)"; }; And don't forget to set size as 'let' variable, since you can't change value of constant.

@@kazimuntasir maybe learn some more actual JavaScript before you do these tutorials. The point of this is not to copy his code but to see what logic is needed and if you know even basic js you can use this logic to build it without needing to copy code. There is no point to copy code if you don’t know how to debug it.

[@chengyugong7951]

Thank you, but how to make the slideshow responsive when you stretch the window? Looks like if I stretch my window bigger or smaller, the image will display inproperly

[@tiaan_va]

It is responsive. Resize your window and refresh the page. No normal person will manually resize a window while they are already busy scrolling. The js uses the client width of the element as it is after the page is loaded. It will stay like that until the page is reloaded at a diff size. So if this loads up on a mobile device it will fit to the smaller views. If you want the client width to be responsive then you need to add an event listener to the window size so it updates while the user changes the window size,but this is overkill and will make the page slower for no good reason since 99.999% of people won’t be actively resizing the window after it has been loaded.

[@jasongaretthatcher]

Great video. Thanks for making it. I occasionally have flickering of the images. Any idea what could be the cause? Is there a solution?
