jquery css edge JavaScript

I'm collaborating on a project where I've looked through the documentation and I'm still confused about I've been struggling with this for a few days now and could really use some help..... I'm working with an scenario where using jQuery's `.fadeIn()` method on a div element does not work as expected in Microsoft Edge. I have the following setup: I'm trying to fade in a modal when a button is clicked, but the fading effect is inconsistent—it sometimes shows without fading or takes too long to appear. Here’s a simplified version of my code: ```html <button id='showModal'>Show Modal</button> <div id='modal' style='display: none; opacity: 0;'>This is a modal.</div> ``` ```javascript $('#showModal').on('click', function() { $('#modal').fadeIn(400); }); ``` I also have CSS transitions applied to the modal: ```css #modal { transition: opacity 0.5s ease-in-out; } ``` The question arises when the modal is displayed; the jQuery `.fadeIn()` seems to conflict with the CSS transitions. On some occasions, the modal appears immediately without fading in at all. I’ve tested it on the latest version of Edge, and it behaves inconsistently. I’ve tried removing the CSS transition and the fade works as expected, but I want to keep the CSS for smooth transitions. I also checked for any conflicting scripts or styles but everything seems fine. Has anyone encountered similar issues, or does anyone know a workaround for this? For context: I'm using Javascript on macOS. I'd really appreciate any guidance on this. I'm developing on Ubuntu 22.04 with Javascript. I'm open to any suggestions. This is my first time working with Javascript LTS. Any suggestions would be helpful. This is part of a larger application I'm building. Thanks, I really appreciate it!
