How can I implement theming in my React app using CSS modules?

You can implement theming in your React app by creating separate CSS module files for each theme and conditionally applying them based on the user's selection.

Can you give me an example of how to switch themes?

Sure! You can use a state variable to track the current theme and toggle it with a button. Here's a simple example:

const [theme, setTheme] = useState('light');

const toggleTheme = () => {
  setTheme(prevTheme => (prevTheme === 'light' ? 'dark' : 'light'));
};

return (
  <div className={styles[theme]}>
    <button onClick={toggleTheme}>Switch Theme</button>
  </div>
);

What if I want to add more themes?

You can extend the state to include more themes by using an array or an object to manage the theme styles. Just ensure you update the toggle function to cycle through the available themes.

Are there any libraries that can help with theming?

Yes, libraries like styled-components or emotion can help manage theming more effectively, allowing for dynamic styling and easier theme management.
