CSS Fixed Positioning Not Working as Expected with Scrollable Container in Vue 3
Can someone help me understand I'm having trouble with I'm prototyping a solution and I'm trying to debug I'm trying to implement a fixed positioning for a header within a scrollable container in my Vue 3 application, but it seems to be misbehaving. The header is supposed to stay fixed at the top of the scrollable container, but when I scroll down, it jumps outside of the container instead of sticking in place. Here's a simplified version of my component template: ```html <template> <div class="scrollable-container"> <header class="fixed-header">I should stay fixed</header> <div class="content"> <!-- Lots of content here to make it scrollable --> <p v-for="i in 100" :key="i">Line {{ i }}</p> </div> </div> </template> ``` And here’s the CSS I am using: ```css .scrollable-container { position: relative; height: 400px; overflow-y: auto; border: 1px solid #ccc; } .fixed-header { position: sticky; top: 0; background: white; padding: 10px; z-index: 10; border-bottom: 1px solid #ddd; } .content { height: 1000px; /* Large enough to enable scrolling */ } ``` I've tried changing the `position` of the header to `fixed`, but then it removes it from the flow of the container entirely, causing it to overlap with other elements. The `sticky` positioning seemed like a good idea since it should allow the header to remain fixed at the top of the scrollable area, but it doesn't appear to be working as intended. In addition, when I inspect the layout, the header seems to lose its `sticky` positioning after the first scroll. I double-checked that there aren't any conflicting styles or JavaScript that might be affecting it, and I am using Vue 3 with a basic setup (no additional frameworks like Bootstrap). Any advice on how to ensure the header stays at the top of the scrollable area would be greatly appreciated! What are your experiences with this? I appreciate any insights! I recently upgraded to Html/Css 3.9. I'd be grateful for any help. I'm working in a CentOS environment. Could this be a known issue?
