jQuery .animate() causing layout shift and unexpected results on resizing elements

I'm prototyping a solution and I'm working with a frustrating scenario with jQuery's `.animate()` method when trying to animate the width of dynamically generated elements. I've set up a scenario where I want to smoothly transition the width of a set of divs from 100px to 200px upon a button click. However, when resizing the browser window, the animations behave unpredictably, causing layout shifts and sometimes even resulting in elements being pushed off-screen. Here's the code I'm using: ```javascript $(document).ready(function() { $('#animateButton').on('click', function() { $('.box').animate({ width: '200px' }, 500); }); }); ``` The `.box` class is applied to multiple divs that are generated dynamically based on user input. Each div has a fixed position, but when the animation occurs and I resize the window, the calculations for the widths seem to go awry. I notice that the elements sometimes flash back to their original sizes or overlap each other. I tried wrapping the `.animate()` call inside a debounce function to limit how often it runs on resize, but that didn't resolve the core scenario. Additionally, I ensured that my CSS does not include any conflicting styles. I am using jQuery version 3.6.0 and testing in Chrome and Firefox. As a workaround, I considered using CSS transitions instead, but I want to find a way to fix this scenario directly with jQuery if possible. Has anyone experienced similar issues, and what solutions did you find? Any insights would be greatly appreciated! This is part of a larger mobile app I'm building.
