Difficulty Centering a Fixed Position Element within a Flexbox Container in Chrome
I've spent hours debugging this and I've been banging my head against this for hours... I've looked through the documentation and I'm still confused about I'm having trouble centering a fixed position element within a flexbox container. I have a layout where I want a sidebar on the left and a content area on the right, but I also need to have a button that stays centered in the viewport regardless of scrolling. The button is currently positioned absolutely within a flexbox container, but it seems to be misaligned in Chrome. Here's the relevant CSS and HTML: ```html <div class="container"> <div class="sidebar">Sidebar</div> <div class="content"> <h1>Main Content Area</h1> </div> <button class="fixed-button">Click Me</button> </div> ``` ```css .container { display: flex; height: 100vh; } .sidebar { width: 250px; background-color: #f4f4f4; } .content { flex: 1; background-color: #ffffff; } .fixed-button { position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%); } ``` I've tried adjusting the `top` and `left` properties, but the button seems to be shifting based on the container's dimensions rather than the viewport. In Firefox, it works as expected, but in Chrome, it appears slightly off-center. I've also checked for any potential `box-sizing` issues and ensured there are no margins affecting the layout. Does anyone have any insights or suggestions for resolving this scenario? I'm currently using Chrome version 94.0.4606.61. I'm working on a CLI tool that needs to handle this. My development environment is Linux. Am I missing something obvious? This is part of a larger REST API I'm building. Is this even possible?
