How to change hover color for Ant Design v5 Button with Tokens in React?


When working with Ant Design in a React project, customizing the default styles of components like buttons can sometimes be a bit tricky. One common requirement is to change the hover color of a button using design tokens. In this article, we'll explore how to achieve this using Ant Design v5.

Problem Scenario

The initial task might look something like this: "How to change the hover color of an Ant Design v5 Button component in a React application using tokens?"

Original Code Example

Here’s a basic example of how you might typically create a button in Ant Design without any customization:

import React from 'react';
import { Button } from 'antd';

const App = () => {
    return (
        <div>
            <Button type="primary">Click Me</Button>
        </div>
    );
};

export default App;

Customizing the Hover Color

To modify the hover color of the Ant Design Button, we can use design tokens provided by Ant Design. These tokens help us maintain a consistent design across our application and ensure that our buttons match our desired aesthetic.

Step-by-Step Guide

  1. Install Required Packages: Ensure you have the necessary dependencies installed in your React application. If you haven’t already, you can install Ant Design:

    npm install antd
    
  2. Create a Theme Configuration: You can customize Ant Design's default theme using ConfigProvider. Here’s how to specify the hover color:

import React from 'react';
import { Button, ConfigProvider } from 'antd';

const App = () => {
    return (
        <ConfigProvider
            theme={{
                token: {
                    colorPrimary: '#1DA57A', // Main color
                    colorPrimaryHover: '#3FBF8E' // Hover color
                },
            }}
        >
            <div>
                <Button type="primary">Click Me</Button>
            </div>
        </ConfigProvider>
    );
};

export default App;

Explanation

  • The ConfigProvider allows you to define theme variables that can customize various aspects of Ant Design components globally.
  • In the theme object, you can specify token values such as colorPrimary for the default button color and colorPrimaryHover for the hover effect.
  • By updating these values, every primary button in your application will inherit the new styles.

Additional Considerations

  • Responsive Design: Ensure that your hover colors are accessible and maintain contrast for users with visual impairments. Use tools like WebAIM's Contrast Checker to test your color combinations.
  • Custom Styling: If you want more complex hover effects, consider using CSS-in-JS libraries like Styled Components or Emotion to add conditional styles based on user interaction.
  • Ant Design Documentation: For more detailed information on theming and tokens, refer to the Ant Design documentation.

Conclusion

Customizing the hover color of buttons in Ant Design v5 using tokens is a straightforward process that allows for a cohesive design throughout your application. By following the steps outlined above, you can easily adjust your button styles to align with your brand identity.

Useful Resources

By using design tokens, you can not only change hover colors but also keep your application consistent with a well-defined design system. Embrace these customizations to enhance the user experience in your React applications!
