jquery bootstrap-5 css javascript

I'm refactoring my project and I'm sure I'm missing something obvious here, but I'm trying to debug I'm a bit lost with I've spent hours debugging this and I'm reviewing some code and Quick question that's been bugging me - I'm working with an scenario where I'm trying to dynamically apply styles to elements within a Bootstrap 5 modal using jQuery, but the styles are not being applied as expected..... Specifically, I have a modal with a button that, when clicked, should change the background color of a div inside the modal. The question arises because the div starts off with `display: none;` until the modal is opened. I'm using jQuery 3.6.0. Here's the relevant code snippet: ```html <!-- Bootstrap Modal Structure --> <div class="modal fade" id="myModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal Title</h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> <div id="myDiv" style="display: none;">Hello, World!</div> <button id="changeColor">Change Color</button> </div> </div> </div> </div> ``` ```javascript $(document).ready(function() { $('#myModal').on('shown.bs.modal', function () { $('#myDiv').show(); // Show the div when modal is opened }); $('#changeColor').on('click', function() { $('#myDiv').css('background-color', 'yellow'); }); }); ``` The scenario is that when I click the 'Change Color' button, I expect the background color of `#myDiv` to change, but nothing happens. In the console, I also see that there are no behavior messages, and when I inspect the element, the inline style for the background color is not added. I've tried using `$('#myDiv').css('display', 'block');` before changing the color, but that doesn't fix it either. Any insights on why the styles aren't being applied properly? Is there a limitation with how jQuery interacts with Bootstrap modals in this context? Any help would be greatly appreciated! Any ideas what could be causing this? I recently upgraded to Javascript 3.9. Cheers for any assistance! For reference, this is a production web app. Thanks for any help you can provide! Any help would be greatly appreciated!
