Inline CSS styles in React: how to implement a:hover?

When working with React, you may come across the need to apply inline CSS styles to your components. While React provides a convenient way to apply styles using JavaScript objects, implementing pseudo-classes like :hover can be a bit tricky. In this blog post, we will explore different approaches to implement a:hover in React.

Approach 1: Using the style prop

The simplest way to implement a:hover in React is by using the style prop. By dynamically updating the style object based on the hover state, we can achieve the desired effect.

{`import React, { useState } from 'react';

function MyComponent() {
  const [isHovered, setIsHovered] = useState(false);

  const handleMouseEnter = () => {
    setIsHovered(true);
  };

  const handleMouseLeave = () => {
    setIsHovered(false);
  };

  const linkStyle = {
    color: isHovered ? 'red' : 'blue',
    textDecoration: 'underline',
  };

  return (
    
      Hover me!
    
  );
}`}

In this example, we use the useState hook to manage the hover state. When the mouse enters the link, we update the state to true, and when it leaves, we update it to false. The linkStyle object is updated accordingly, changing the color to red when hovered.

Approach 2: Using CSS Modules

If you prefer to keep your styles separate from your components, you can use CSS Modules to achieve a:hover in React. CSS Modules allow you to write CSS styles in separate files and import them as objects in your components.

{`import React from 'react';
import styles from './MyComponent.module.css';

function MyComponent() {
  return (
    
      Hover me!
    
  );
}`}

In this example, we define the link class in a separate CSS file named MyComponent.module.css. We can then import the styles using the styles object and apply the link class to the a element.

In MyComponent.module.css:

{`.link {
  color: blue;
  text-decoration: underline;
}

.link:hover {
  color: red;
}`}

By defining the .link:hover class, we can easily apply the a:hover effect using CSS Modules.

Final Thoughts

Implementing a:hover in React can be achieved using different approaches. Whether you prefer inline styles or separate CSS files with CSS Modules, both methods provide a way to apply the desired effect. Choose the approach that best suits your project’s needs and coding style.
