How to toggle CSS styles with Toggle method in React

This is Header component with React-Bootstrap. I created a menu icon with pure CSS but I want to change the icon function onClick but I’m getting the error – TypeError: Cannot read property 'toggle' of undefined . It’s there any way I’m getting it wrongly? Kindly check. Thanks.

Also, it’s there a way, I can handle this with React Hooks method instead?


import styles from './Landing.module.css';
import './Landing.module.css';;

const openMenu = (open) => {

 <Nav className="ml-auto">
  <div className={styles.allMenus}>
    <div className="menuIcon" onClick={openMenu}>
       <div className={styles.bar1}></div>
         <div className={styles.bar2}></div>
           <div className={styles.bar3}></div>

My CSS – It has the change styles

div[class="menuIcon"] {
    background-color: #ffffff;
    padding: 13px;
    margin-right: 46px;
    float: right;
    cursor: pointer;

.bar1, .bar2, .bar3 {
    width: 32px;
    height: 3px;
    background-color: #333;
    margin: 6px 0;
    transition: 0.4s;

.change .bar1 {
    -webkit-transform: rotate(-45deg) translate(-9px, 6px) ;
    transform: rotate(-45deg) translate(-9px, 6px) ;
.change .bar2 {
    opacity: 0;
.change .bar3 {
    -webkit-transform: rotate(45deg) translate(-8px, -8px) ;
    transform: rotate(45deg) translate(-8px, -8px) ;
