CSS flexbox IE11 cross-browser

I'm relatively new to this, so bear with me. I'm working with a frustrating scenario where my flexbox layout works perfectly in modern browsers but completely breaks in Internet Explorer 11. The layout is supposed to display three items in a row, centered vertically and horizontally. However, in IE11, the items end up stacked vertically instead of alongside each other, and the alignment properties seem to be ignored. Here’s the relevant CSS code I’m using: ```css .container { display: flex; justify-content: center; align-items: center; height: 100vh; } .item { flex: 1; margin: 10px; background-color: lightblue; padding: 20px; box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3); } ``` I also added a fallback for older browsers: ```css @supports not (display: flex) { .container { display: block; } .item { display: inline-block; width: 30%; margin: 10px; } } ``` I’ve tried using `-ms-` prefixes and ensuring that `flex-wrap` is set to `nowrap`, but nothing seems to work in IE11. The scenario is particularly prevalent when the viewport is narrower than 600px, which is when I expect it to stack up correctly using the fallback. However, it still doesn’t respond as intended. When inspecting the layout in IE11 DevTools, I see that the `.container` is recognized as a flex container, but the `.item` elements aren’t behaving as flex items. I also checked for any console errors that might indicate issues with my CSS, but there are none. Has anyone encountered this scenario before? Any suggestions on how to get this flexbox layout to work properly in IE11?
