CSS Sticky Position optimization guide in Safari with Scrollable Flex Container
I keep running into I'm working on a personal project and Quick question that's been bugging me - Hey everyone, I'm running into an issue that's driving me crazy. I'm trying to create a sticky header that stays at the top of a flex container when scrolling, but it's not working in Safari. My layout uses a flexbox to arrange some cards and I've set up the header with `position: sticky; top: 0;` but it's not behaving as expected. In Chrome and Firefox, it works perfectly, but in Safari, the header scrolls away with the content instead of sticking at the top. Here’s the relevant CSS: ```css .container { display: flex; flex-direction: column; height: 300px; overflow-y: auto; } .header { position: sticky; top: 0; background: white; z-index: 10; } .card { height: 100px; border: 1px solid #ccc; margin: 5px; } ``` And here’s the HTML structure: ```html <div class="container"> <div class="header">Sticky Header</div> <div class="card">Card 1</div> <div class="card">Card 2</div> <div class="card">Card 3</div> <div class="card">Card 4</div> <div class="card">Card 5</div> </div> ``` I've tried adjusting the `z-index` and ensuring the parent container has a defined height, but nothing seems to work in Safari. I also checked for any browser-specific prefixes, but that didn’t help either. Is there a known scenario or workaround for getting sticky positioning to work in Safari under these circumstances? Any insights would be appreciated! What's the best practice here? This is part of a larger service I'm building. I'm using Css 3.11 in this project. How would you solve this? I'm on macOS using the latest version of Css. Is this even possible?
