I've been struggling with this for a few days now and could really use some help. I've been banging my head against this for hours... I'm facing an issue where a CSS animation is not triggering when focusing on an input field inside a modal using Bootstrap 5. The modal is being displayed properly, but the `:focus` styles I’ve defined for the input field don't seem to apply as expected. Here’s the CSS I’m using: ```css .input-highlight:focus { animation: highlight 0.5s ease; } @keyframes highlight { 0% { border-color: blue; } 100% { border-color: green; } } ``` And here’s the relevant HTML structure: ```html <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> <input type="text" class="form-control input-highlight" placeholder="Type here..." /> </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> </div> </div> </div> </div> ``` I’ve tried adding `!important` to the border color in the focus state but that didn’t work. The animation seems to be skipped altogether when I focus on the input inside the modal. I also confirmed that the modal is not interfering; the animation works on a regular input outside of the modal context. Am I missing something in terms of CSS specificity or is there a Bootstrap class that may be conflicting with my styles? Any insights would be appreciated! I've been using Html/Css for about a year now. Thanks in advance! I'm on Ubuntu 20.04 using the latest version of Html/Css. Any ideas what could be causing this?
