vue.js css transitions HTML/CSS

I've hit a wall trying to I'm experimenting with I'm working on a Vue.js project and I'm having trouble with CSS transitions not triggering when I dynamically change classes on an element... I have a component where I toggle between two classes based on a boolean state, but the transition only works when I manually change the class via the browser's developer tools. Here's a simplified version of my code: ```html <template> <div :class="{ 'fade': isFaded, 'show': !isFaded }" @click="toggleFade"> Click me to toggle fade </div> </template> <script> export default { data() { return { isFaded: false }; }, methods: { toggleFade() { this.isFaded = !this.isFaded; } } }; </script> <style scoped> .fade { opacity: 0; transition: opacity 0.5s ease-in-out; } .show { opacity: 1; } </style> ``` When I click the div, the class changes, but the opacity does not animate. The `toggleFade` method is updating `isFaded`, and I can see the class toggling in the inspector, but the transition does not happen as expected. I’ve tried adding `!important` to the transition property and ensuring my styles are scoped correctly, but nothing seems to work. Is there a specific Vue.js or CSS limitation I'm running into here, or am I missing something in my implementation? My team is using Html/Css for this application. Thanks in advance! Thanks for taking the time to read this! Is this even possible?
