CSS hover effect optimization guide on dynamically added elements in React
I'm building a feature where I'm converting an old project and I'm collaborating on a project where I've been struggling with this for a few days now and could really use some help... I'm working with an scenario where I'm trying to apply a hover effect on elements that are dynamically added to the DOM using React. Essentially, I have a list of items that is rendered based on an array, and I want to change the background color of each item on hover. I wrote the following CSS for the hover effect: ```css .item { background-color: white; transition: background-color 0.3s; } .item:hover { background-color: lightblue; } ``` In my React component, I'm mapping over an array of data like this: ```jsx const items = ['Item 1', 'Item 2', 'Item 3']; const ItemList = () => ( <div> {items.map((item, index) => ( <div key={index} className="item">{item}</div> ))} </div> ); ``` The question is that the hover effect doesn't seem to be applied at all. I have inspected the elements, and the hover styles are not being registered when I hover over them in the browser. I've tried adding `!important` to the hover styles, but that didn't change anything. I also checked if there was any global CSS rule that might be overriding it, but everything looks fine. I'm testing this in Chrome 93, and I need to find any errors in the console. Can anyone guide to understand why the hover effect isn’t working on these dynamically created elements? Is there something I'm missing in my CSS or React implementation? I'm working on a application that needs to handle this. How would you solve this? I'm working on a REST API that needs to handle this. What's the correct way to implement this? Has anyone else encountered this? I'm developing on Windows 10 with Javascript. Cheers for any assistance!
