Answer In React, the `activeClassName` is typically used with the `NavLink` component from the `react-router-dom` library to apply a specific CSS class when the link is active. Here's an example of how you can create a CSS class for use with `activeClassName`:
Let's assume you have a navigation link component like this:
```jsx
import { NavLink } from 'react-router-dom';
const Navigation = () => {
return (
<nav>
<NavLink to="/" activeClassName="active">Home</NavLink>
<NavLink to="/about" activeClassName="active">About</NavLink>
<NavLink to="/contact" activeClassName="active">Contact</NavLink>
</nav>
);
};
```
Now, you want to define the CSS class for the active state. You can do it in your CSS file:
```css
/* styles.css or styles.scss */
.active {
color: red; /* Change this to your desired style for the active link */
font-weight: bold; /* Add any other styles you want for the active link */
/* Add more styles as needed */
}
```
In this example, when a NavLink is active, the "active" class will be applied, and you can customize the styles within that class to achieve the desired appearance for the active link.
Make sure to import your CSS file in the component or at a higher level of your application where it will be applied:
```jsx
import './styles.css'; // Adjust the path based on your file structure
```
Now, when the user navigates to a page corresponding to one of your `NavLink` components, the "active" class will be applied, and the styles you defined for the "active" class will be used.
