Font Awesome icons are widely used in React applications to display icons and visual elements. By default, Font Awesome icons use the default black color. However, in many cases you may want to customize the color of the icons to match visual branding, highlight important icons, etc. In this article, we’ll cover multiple ways to change the color of Font Awesome icons in React apps.
Using the style Property
The easiest way to change the color of a Font Awesome icon is to use the `style` property. This allows you to directly set a CSS color value:
“`jsx
“`
You can set the `color` to any valid CSS color value – named colors like `red` or `green`, hex values like `#ff0000`, rgb values like `rgb(255, 0, 0)`, etc.
Some advantages of using the style property:
– Simple and straightforward to implement
– Works with any icon
– Can be dynamically changed
Some disadvantages:
– Need to set it inline on every icon instance
– Not reusable or abstracted
CSS Classes
Another approach is to create CSS classes to set the color, and apply those classes to the FontAwesomeIcon components.
First, define the classes:
“`css
.red {
color: red;
}
.green {
color: green;
}
“`
Then apply them:
“`jsx
“`
Some benefits of using CSS classes:
– Can reuse classes for consistency
– Keeps styling separate from logic
– Easier to change colors down the road
Drawbacks:
– Need to define CSS somewhere
– Slightly more involved setup
Sass Variables
For larger apps, you may want to define Sass variables for your colors so they are centralized and reusable.
In your Sass:
“`scss
$icon-color-red: red;
$icon-color-green: green;
“`
Then in your CSS:
“`css
.icon-red {
color: $icon-color-red;
}
.icon-green {
color: $icon-color-green;
}
“`
And applying the classes:
“`jsx
“`
Advantages of this approach:
– Colors are defined in one place
– Easily reusable across components
– Changing color themes is simpler
Disadvantages:
– More setup required
– Need experience with Sass preprocessing
CSS Modules
CSS Modules scope CSS by automatically generating unique class names. This allows using shorthand CSS without worrying about naming collisions.
Define CSS module:
“`css
/* IconStyles.module.css */
.red {
color: red;
}
.green {
color: green;
}
“`
Import and use in React:
“`jsx
import styles from ‘./IconStyles.module.css’;
“`
Benefits of CSS modules:
– Avoid naming collisions
– Scoped styles
– Can co-locate CSS with components
Downsides:
– Additional setup/build configuration
– Class names aren’t readable
Styled Components
Styled components let you write actual CSS code inside JavaScript. This allows you to define styled components with unique names.
“`jsx
// IconStyles.js
import styled from ‘styled-components’;
export const RedIcon = styled(FontAwesomeIcon)`
color: red;
`;
export const GreenIcon = styled(FontAwesomeIcon)`
color: green;
`;
“`
Use like:
“`jsx
import { RedIcon, GreenIcon } from ‘./IconStyles’;
“`
Pros of styled components:
– CSS-in-JS approach
– Unique generated class names
– Easily themeable
Cons:
– Relies on third-party library
– Introduces new concepts/patterns
Conclusion
There are a variety of effective ways to customize the color of Font Awesome icons in React apps. The best approach depends on your preferences and needs:
– The `style` prop offers a quick and easy method ideal for one-off icon customization.
– CSS classes provide reusable styles that abstract styling away from components.
– Sass variables and CSS modules require more setup but offer scalability and maintainability benefits.
– Styled components give you CSS-in-JS capabilities for theming and encapsulation.
Try out the different options to see what makes the most sense for your project and development team. Having consistent, branded icons can greatly improve the user experience of any React application.
