css flexbox sticky-header HTML/CSS

I've looked through the documentation and I'm still confused about I've spent hours debugging this and Hey everyone, I'm running into an issue that's driving me crazy. I'm trying to implement a sticky header using CSS, but it's not behaving as I expected in Chrome. The header is inside a nested flexbox layout, and while it sticks correctly at the top of the viewport on scroll, the content below it seems to overlap with the header instead of respecting its height. I have this structure: ```html <div class="container"> <header class="sticky-header">Sticky Header</header> <div class="content"> <div class="item">Item 1</div> <div class="item">Item 2</div> </div> </div> ``` And my CSS is as follows: ```css .container { display: flex; flex-direction: column; } .sticky-header { position: sticky; top: 0; background-color: white; z-index: 10; } .content { display: flex; flex-wrap: wrap; margin-top: 0; } .item { width: 50%; padding: 20px; box-sizing: border-box; } ``` I expected that the `sticky-header` would stay visible while I scroll through the `content` below, but instead, the items overlap the sticky header. I checked for common issues, like ensuring that the z-index is set high enough and that the header has a background color, but nothing seems to resolve the question. I'm using Chrome version 95.0.4638.69. Does anyone have a solution or a workaround for this sticky header scenario with nested flexbox layouts? I'm working on a API that needs to handle this. Thanks in advance! Thanks for your help in advance! Any help would be greatly appreciated! I'm working with Html/Css in a Docker container on Windows 10. Am I approaching this the right way?
