Passing classnames as a props to the React component
In this tutorial, we are going to learn about how to pass the classnames as a props to the react component.
Consider, we have a Button component like this in our react app.
Button.js
import React from "react";
export default function Button(props) {
return <button>{props.children}</button>;}Now, we need to pass a css classname to the <Button> component from a <App> component.
To do this, first we need to add a prop name to the <Button> component.
Button.js
import React from "react";
export default function Button(props) {
return <button className={props.cname}>{props.children}</button>;}Now, inside an App component we can pass a classname to the Button component using cname prop.
App.js
import React from "react";
import "./styles.css";
import Button from "Button";
export default function App() {
return (
<div className="App">
<h1>Hello React App</h1>
<Button cname="default-1">Default</Button> </div>
);
}Sometimes, there is a default classname in Button component and we need to pass extra classname from an App component.
For that, we need to use template literals to interpolate the extra classname.
Button.js
import React from "react";
function Button(props) {
return (
<button className={`box ${props.cname}`}> {props.children}
</button>;
);
