What is the best way to reveal the menu options by tapping on the top left icon?

Seeking guidance on how to activate the menu by clicking the top left corner icon. A sample code setup is available in Codepen through this link: https://codepen.io/RSH87/pen/rmgYbo. I require assistance with incorporating the JavaScript file into my React application. Attached below is a screenshot demonstrating my React code structure.


        /*App.js file */

        import './App.css';

        function App() {
          return (
            <div className="App">
              <div className="menu-icon">

                  <span className="menu-icon__line menu-icon__line-left"></span>
                  <span className="menu-icon__line"></span>
                  <span className="menu-icon__line menu-icon__line-right"></span>
              </div>

              <div className="nav">

                  <div className="nav__content">
                      <ul className="nav__list">
                          <li className="nav__list-item">Home</li>
                          <li className="nav__list-item">About</li>
                          <li className="nav__list-item">Projects</li>
                          <li className="nav__list-item">Contact</li>
                      </ul>
                  </div>
              </div>

              <div className="site-content">
                  <h1 className="site-content__headline">Polar S2</h1>
              </div>

            </div>
          );
        }

        export default App;


        /*index.js file*/

        import React from 'react';
        import ReactDOM from 'react-dom/client';
        import './index.css';
        import App from './App';
        import reportWebVitals from './reportWebVitals';

        const root = ReactDOM.createRoot(document.getElementById('root'));
        root.render(
          <React.StrictMode>
            <App />
          </React.StrictMode>
        );

        // If you want to start measuring performance in your app, pass a function
        // to log results (for example: reportWebVitals(console.log))

        reportWebVitals();
      

        <!--index.html file--->
        <!DOCTYPE html>
        <html lang="en">
          <head>
            ...
          </body>
        </html>
      

View output of my React app

Desired output post-clicking top-left corner icon

Answer №1

Utilize the useEffect hook to execute a function after the DOM has been mounted successfully.

App.js


import {useEffect} from "react";

function App() {

  useEffect(() => {

    // The script can be used from the Codepen.

  },[]);


  return (
    <div className="App">
      <div className="menu-icon">
       ..... blah ... blah
  );
}
