The below code is an example of a React. You have to import "./App.css" and set background-color: rgba(0, 0, 0, 0.5); in .overlay to add black overlay on image in react using css.

import logo from "./beautiful-nature.jpeg"

const App = () => {
  return (
    <div className="image-container">
      <img src={logo} alt="Example" className="image" />
      <div className="overlay"></div>
    </div>
  );
};

export default App;

App.css

.image-container {
  position: relative;
  display: inline-block;
}

.image {
  width: 50%;
  height: 50%;
  display: block;
}

.overlay {
  position: absolute;
  top: 0;
  left: 0;
  width: 50%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5); /* Black with 50% opacity */
  z-index: 1; /* Layer it above the image */
  pointer-events: none; /* Prevent it from blocking interactions */
}
