react html css javascript

I'm confused about Quick question that's been bugging me - I'm working on a personal project and I'm experiencing an issue with dynamically generated HTML elements in a React 18 application. When I add elements to the DOM, they lose their CSS styles that are defined in an external stylesheet. For instance, I have a button that I create programmatically, but it appears unstyled after being rendered. Here’s a simplified version of my code: ```javascript import React from 'react'; import './styles.css'; // This imports my stylesheet function App() { const handleAddButton = () => { const button = document.createElement('button'); button.innerText = 'Click Me'; button.classList.add('my-button'); // Class defined in styles.css document.body.appendChild(button); }; return ( <div> <h1>Dynamic Button Example</h1> <button onClick={handleAddButton}>Add Button</button> </div> ); } export default App; ``` In my `styles.css`, I have the following class defined: ```css .my-button { background-color: blue; color: white; padding: 10px 20px; border: none; border-radius: 5px; } ``` When I click the "Add Button", the button appears, but it doesn’t have any of the styles applied. I’ve checked to ensure the CSS file is linked correctly, and I can see the class in the button element when inspecting it in the browser. The styles are applied to other static buttons in my app, so it seems to be an issue specifically with this dynamically created button. I've also tried forcing a reflow after appending the button, but that didn’t help either. Is there something specific I need to do in React to ensure dynamically added elements retain their styles? I'm working on a web app that needs to handle this. Thanks in advance! This is happening in both development and production on CentOS. Thanks, I really appreciate it! I'm working on a REST API that needs to handle this. What would be the recommended way to handle this? I'm developing on Windows 11 with Javascript. I'd love to hear your thoughts on this. For context: I'm using Javascript on CentOS.
