Change the text color on click in React

In this tutorial, we are going to learn about how to change the text color on click in React with the help of an example.

Consider, we have the following component in our react app:

import React from 'react';

function Home(){
    return (
        <div>
          <h1>Welcome to my blog</h1>
        </div>
    )
}

export default Home;

To change the text color on click in React, add the onClick event handler and change the text color of an element conditionally whenever it’s clicked using the state variable.

Here is an example:

import React, { useState } from "react";

function Home() {
  const [active, setActive] = useState(false);

  const handleClick = () => {
    setActive(!active);
  };

  return (
    <div>
       <h1
        onClick={handleClick}
        style={{ color: active ? "black" : "white" }}
       >
        Welcome to my blog
      </h1>
    </div>
  );
}

export default Home;

In the example above, we added a handleClick event handler to the onClick prop and state active to the style property, so whenever a h1 element is clicked it runs the handleClick function and changes the active state from false to true or vice versa.

Based on the active state we are changing the h1 text Color using the ternary expression.

{color: active ? "black" : "white" }

If active is false it chooses the white color, if its true it chooses the black color.

If you are styling your element text using css classes, then you can toggle between two css classnames like this:

Here is an example:

import React, { useState } from "react";

function Home() {
  const [active, setActive] = useState(false);
  const handleClick = () => {
    setActive(!active);
  };

  return (
      <div>
       <h1
         onClick={handleClick}
         className={active ? "default" : "success"}
       >
         Welcome to my blog
      </h1>
    </div>
  );
}

export default Home;

In the example above, if active state is true it chooses default class, if active state is false it chooses success class.
