Use inline styles to set the text color of an element in React.js.
The text color will only be applied to the element to which it was added and its children.
const App = () => { return ( <div> <p style={{fontSize: '2rem'}}> Some{' '} <span style={{color: 'white', backgroundColor: 'lime'}}>colorful</span>{' '} text </p> </div> ); }; export default App;
We used inline styles to change the text color of an element.
The first set of curly braces in the inline style marks the beginning of an expression and the second set of curly braces is the object containing styles and values.
The changed text color is only going to be applied to the span
element.
If you need to do this often, you can extract the span
element into a
component that renders its children.
function ColorfulText({children}) { return <span style={{color: 'green'}}>{children}</span>; } const App = () => { return ( <div> <p style={{fontSize: '2rem'}}> Some <ColorfulText>colorful</ColorfulText> text </p> </div> ); }; export default App;
Whatever we pass between the opening and closing tags of the ColorfulText
component will have the specific text color applied.

An alternative solution is to define a class in a global CSS file.
.red-text { color: red; }
And here is how we would import the App.css
file and use the red-text
class.
import './App.css'; const App = () => { return ( <div> <p style={{fontSize: '2rem'}}> Some <span className="red-text">colorful</span> text </p> </div> ); }; export default App;
This approach enables us to reuse commonly used styles by defining them in a global CSS file.
It's a best practice to import your global CSS files in your index.js
file
because then they wouldn't only get loaded when a certain component is mounted.

You can use the ternary operator to conditionally set the text color in React.
import {useState} from 'react'; const App = () => { const [isColored, setIsColored] = useState(false); return ( <div> <p> bobby <span style={{color: isColored ? 'green' : ''}}>hadz</span> .com </p> <button onClick={() => setIsColored(isColored => !isColored)}> Toggle isColored </button> </div> ); }; export default App;
The code sample only sets the text color when the isColored
state variable is
is true
.
The ternary operator is
very similar to an if/else
statement.
If the expression to the left of the question mark is truthy, the operator returns the value to the left of the colon, otherwise, the value to the right of the colon is returned.
<p> bobby <span style={{color: isColored ? 'green' : ''}}>hadz</span> .com </p>
You can imagine that the value before the colon is the if
block and the value
after the colon is the else
block.
If the isColored
variable stores a true
value, the string green
is
returned, otherwise, an empty string is returned.
