CSS Sticky Positioning optimization guide as Expected in Safari 17 for Nested Elements
I'm having a hard time understanding I'm having trouble with using `position: sticky;` in a layout that's nested within Flexbox containers. The goal is to have a sidebar that remains sticky while the main content scrolls, but it's not working correctly in Safari 17. In Chrome and Firefox, it behaves as expected, but in Safari, the sidebar scrolls with the content instead of sticking to the viewport. I've tried adjusting the parent containers' styles and ensuring that the sticky element has a defined `top` value. Here's a simplified version of my CSS: ```css .container { display: flex; height: 100vh; } .sidebar { position: sticky; top: 0; height: 100vh; background: lightblue; } .content { flex: 1; overflow-y: auto; height: 200vh; /* Simulating a long content area */ } ``` And the accompanying HTML: ```html <div class="container"> <div class="sidebar"> <p>Sticky Sidebar</p> </div> <div class="content"> <p>Main content area. Scroll down...</p> <!-- Lots of content here --> </div> </div> ``` I've checked for `overflow` settings and ensured that there are no conflicting styles that might affect the sticky behavior. I even tried using a wrapper div without flex but that didn't help either. In the inspector, the sidebar shows `position: sticky;` but it behaves like `relative;` instead. Has anyone encountered this scenario or have suggestions on how to make it work in Safari? Any help would be greatly appreciated! I'm coming from a different tech stack and learning Css. Is there a simpler solution I'm overlooking?
