My current challenge involves utilizing ReactDOM.createPortal to create a global modal that can be accessed from any page within the React app. The modal opens and displays correctly, but I have encountered an issue where the and elements inside the modal are unresponsive to clicks.

The problem is not related to the onClick functions not working; rather, it seems that these elements cannot be clicked on at all. Neither the anchor nor the button reacts when attempting to interact with them. Despite rendering as expected, both elements fail to respond to mouse clicks. Ideally, either the anchor or the button should serve to close the modal.

Since I was unable to make the anchor or button clickable, I attempted to attach a click event to the overlay div positioned behind the modal dialog div, effectively covering the rest of the page. While this solution technically works, it proves impractical as clicking anywhere within the modal dialog triggers the same click event.

Modal.tsx

import ReactDOM from "react-dom";
import './Modal.css';
export default function Modal(props:any){
    const handleCloseClick = () => {
        props.onClose();
    };

    const modalContent = (
        <div className="modal-overlay" onClick={handleCloseClick}>
            <div className="modal-dialog">
                <div className="modal-header d-flex justify-content-between">
                    <span>{props.title}</span>
                    <a href="#" onClick={handleCloseClick}>X</a>
                </div>
                <div className="modal-body">
                    <p>Modal content goes here</p>
                    <button>TEST</button>
                </div>
            </div>
        </div>
    )

    return ReactDOM.createPortal(modalContent, document.body as Element);
}

Modal.css

.modal-overlay {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    display: flex;
    justify-content: center;
    align-items: center;
    background-color: rgba(0, 0, 0, 0.5);
    z-index: 99;
}

.modal-dialog {
    width: 500px;
    height: 300px;
    background-color: white;
    z-index: 100;
}

.modal-body {
    padding-top: 10px;
}

.modal-header {
    display: flex;
    justify-content: flex-end;
    font-size: 25px;
}

RootLayout.tsx contains the 'Open Modal' button along with the management of the modal's visibility state.

import { Link, Outlet } from 'react-router-dom';
import { useAuth, UseLogin, UseLogout } from '../authentication.context';
import Login from './Login';
import './RootLayout.css';
import { useEffect, useState } from 'react';
import Modal from './Modal';
export default function RootLayout(props: any) {
    const { state, dispatch } = useAuth();
    const [modalVisible, setModalVisible] = useState(false);

    const handleLogout = () => {
        const actions = UseLogout();
        dispatch(actions);
    }

    useEffect(() => {
        if (state) {
            console.log('state in RootLayout:');
            console.log(state);
        }
    }, [state]);

    if (state && state.isAuthenticated) {
        return (
            <div className='h-100'>
                <nav className='navbar navbar-expand-md border border-bottom'>
                    <div className='container-fluid'>
                        <a className="navbar-brand" href="#">JOC Dashboard</a>
                        <button className="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="SupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                            <span className="navbar-toggler-icon"></span>
                        </button>
                        <div className="collapse navbar-collapse" id="navbarSupportedContent">
                            <ul className="navbar-nav me-auto mb-2 mb-lg-0">
                                <li className="nav-item">
                                    <Link className='nav-link active' to="/">Home</Link>
                                </li>
                            </ul>

                            <div className='d-flex justify-content-between align-items-center'>
                                {state.user &&
                                    <div className='me-3'>Logged in as {state.user.full_name}</div>
                                }

                                <div className=''>
                                    <button className='btn btn-primary' onClick={handleLogout}>LOGOUT</button>
                                </div>
                            </div>
                        </div>
                    </div>
                </nav>
                <div id="root-layout-container" className='container-fluid'>
                    <div className='row'>
                        <div className='col-lg-2'>
                            <div className='d-flex flex-column'>
                                <button onClick={() => setModalVisible(true)}>Open Modal</button>
                            </div>  
                        </div>
                        <div className='col-lg-10'>
                            <Outlet/>
                        </div>
                    </div>
                </div>
                {modalVisible &&
                    <Modal title="Title" onClose={() => setModalVisible(false)}/>
                }
            </div>
            
                
        )
    }

    return (
        <div id="root-layout-container" className='container-fluid h-100'>
            {state && !state.isAuthenticated &&
                <Login />
            }
        </div>
    )
}

I've thoroughly checked the z-index values for each modal div and found no overlaps obstructing the anchor or button elements. However, despite my efforts, these components remain unclickable. Can you suggest other factors that may be preventing these elements from being interactive?
