![]() The next piece of the puzzle is that most carousels have little indicator buttons that let you navigate between the items in the list.įor this, we will need a little bit of JavaScript. We don’t have to use touchmove listeners or requestAnimationFrame to try to get the pixel-perfect snapping behavior with the right animation curve – the browser handles all of it for us, in native code.Īnd unlike touchmove, this scroll-snapping works for any method of scrolling – touchpad, touchscreen, scrollbar, you name it. The benefit of having all this “snapping” logic inside of CSS rather than JavaScript is that the browser is doing the heavy lifting. Note: for best results, you may want to view the above pen in full mode. It doesn’t even require JavaScript – just HTML and CSS! As usual for iOS Safari, you’ll also need to add -webkit-overflow-scrolling: touch to make the element scrollable.īut lo and behold, we now have the world’s simplest carousel implementation. You can detect support using (scroll-snap-align: start). The only trick is that you have to write one implementation for the modern scroll snap API (supported by Chrome and Safari), and another for the older scroll snap points API (supported by Firefox ). Ah I knew it was something with white-space.Thanks a lot for your time larin555. You need to add -webkit-overflow-scroll: touch on the element that has overflow:scroll, i.e. In addition, you should explicitly set fixed widths/heights on the body tag representing the size of your device. ![]() The final div should have a min-height of 101. scroll clips the overflowing content and provides scrollbars so the user can scroll the. The key was to wrap the content in 3 divs with -webkit-touch-overflow:scroll applied to them. This is what makes the scrollable element “snap” to a certain position as you scroll it. This prevents a user from scrolling overflowed content into view. My carousel implementation uses a few simple building blocks: Originally a single property for controlling overflowing content in both horizontal & vertical directions, the overflow property is now a shorthand for overflow. Pan or scroll around in any direction, like in an interactive map. ![]() Navigate between images, articles or posts in libraries and galleries. You need to track the y position to make it work. Prototype scrolling with overflow behavior Scroll up or down on a long page of content Scroll left-to-right to view different elements in a slider. Isn’t there a decent way to build a carousel with native browser APIs?Īs it turns out, there is. Its unfortunate that -webkit-overflow-scrolling doesnt handle this better. The problem is that this often adds a large dependency size, or the code is inflexible, or it’s framework-specific (React, Vue, etc.), or it may not be optimized for performance and accessibility.Ĭome on, it’s 2019. Often when you’re building something like this, it’s tempting to use an off-the-shelf solution.
