jquery css responsive JavaScript

I've tried everything I can think of but I'm trying to implement I've been banging my head against this for hours. I'm stuck on something that should probably be simple... I've been banging my head against this for hours. I've been banging my head against this for hours... I'm experiencing an scenario where I'm trying to apply different CSS styles to an element based on the viewport size using jQuery, but it doesn't seem to work as expected. I'm using jQuery version 3.6.0. Here's a simplified version of my code: ```javascript $(document).ready(function() { function adjustStyles() { if ($(window).width() < 600) { $('#myElement').css({'background-color': 'red', 'font-size': '12px'}); } else { $('#myElement').css({'background-color': 'blue', 'font-size': '16px'}); } } adjustStyles(); // Initial call $(window).resize(adjustStyles); // Call on resize }); ``` Initially, when the page loads, the styles are applied correctly based on the viewport size. However, when I resize the window, the styles do not change dynamically or they flicker as the window resizes, sometimes showing incorrect styles in between. The console does not show any errors, but I suspect it has something to do with how the resizing event is being handled. I also tried adding a debounce function to limit the frequency of the `resize` event calls, but it didn't resolve the flickering scenario. Here’s my debounce function: ```javascript function debounce(func, wait) { let timeout; return function executedFunction(...args) { const later = () => { timeout = null; func(...args); }; clearTimeout(timeout); timeout = setTimeout(later, wait); }; } $(window).resize(debounce(adjustStyles, 100)); ``` After applying the debounce, the flickering is less severe, but I can still see the wrong styles being applied briefly during resizing. Is there a better way to handle dynamic style changes with jQuery during window resizing? Any insights or best practices would be greatly appreciated! My development environment is Linux. What's the best practice here? This is part of a larger API I'm building. What am I doing wrong? This is part of a larger CLI tool I'm building. What's the best practice here? This issue appeared after updating to Javascript stable. Hoping someone can shed some light on this. This issue appeared after updating to Javascript 3.10. Has anyone else encountered this?
