<body>
    <div id="myPopup" class="popup">
        <div class="popup-content">

<script>
    function showPopup(message) {
        var popup = document.getElementById('myPopup');
        var messageSpan = document.getElementById('popup-message');

        messageSpan.textContent = message;
        popup.style.display = 'block';
    }

    function hidePopup() {
        var popup = document.getElementById('myPopup');
        popup.style.display = 'none';
    }

    var closeButton = document.getElementById('popup-close');
    closeButton.addEventListener('click', hidePopup);

    var openButton = document.getElementById('popup-open');
    openButton.addEventListener('click', () => showPopup('asdad'));
