CSS transitions optimization guide on hover for dynamically generated elements in Vue.js
I'm testing a new approach and I've searched everywhere and can't find a clear answer. I'm working with an scenario with CSS transitions not triggering properly on hover for elements that are generated dynamically in a Vue.js application. I have a component that renders a list of items based on an API response, and I want to apply a fade effect when hovering over each item. However, the transition seems to be ignored unless I refresh the page. Here's a simplified version of my template: ```html <template> <div class="item-list"> <div v-for="item in items" :key="item.id" class="item" > {{ item.name }} </div> </div> </template> ``` And the corresponding CSS: ```css .item { transition: background-color 0.3s ease; } .item:hover { background-color: lightblue; } ``` I fetch the items in the `mounted()` lifecycle hook: ```javascript mounted() { this.fetchItems(); }, methods: { fetchItems() { axios.get('/api/items').then(response => { this.items = response.data; }); } } ``` I'm using Vue 2.6.14 and noticed that if I manually refresh the page after the items load, the hover effect works as expected. However, if I add new items dynamically while the app is running, the hover transitions do not apply until I refresh. I even tried using `Vue.nextTick()` after updating `this.items`, but the question continues. Is there something I'm missing or a best practice I should follow when dealing with transitions in Vue.js? Any help would be appreciated! My development environment is macOS. Has anyone else encountered this? This is for a service running on Ubuntu 20.04. Any ideas what could be causing this?
