<body>
  <button id="showAlert">Show Custom Alert</button>
  <script src="script.js"></script>
</body>
</html>

2. Create the CSS Styles​

Add the CSS styles to customize the appearance of your alert.

  font-family: Arial, sans-serif;
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
  background-color: #f9f9f9;

3. Create the JavaScript Function​

Implement the JavaScript logic for showing and hiding the custom alert in your script.js file.


const showAlertButton = document.getElementById('showAlert');
const alertOverlay = document.createElement('div');
const alertBox = document.createElement('div');

alertOverlay.classList.add('alert-overlay');
alertBox.classList.add('alert-box');
alertBox.innerHTML = `
  <h2>Custom Alert</h2>
  <p>This is a personalized alert!</p>
  <button id="closeAlert">Close</button>
`;

showAlertButton.addEventListener('click', () => {
  document.body.appendChild(alertOverlay);
  alertOverlay.appendChild(alertBox);
});

alertOverlay.addEventListener('click', event => {
  if (event.target === alertOverlay) {
    alertOverlay.remove();
  }
});

document.addEventListener('click', event => {
  if (event.target.id === 'closeAlert') {
    alertOverlay.remove();
  }
});
