</div>

3. Closable Alerts

Closable alerts provide users the ability to dismiss notifications.

<div class="w3-panel w3-green w3-display-container">
  <span onclick="this.parentElement.style.display='none'" class="w3-button w3-large w3-display-topright">×</span>
  <p>Success: Your message has been sent!</p>
</div>

4. Custom Styled Alerts

You can combine W3.CSS classes to create custom alerts.

  <p><i class="fa fa-info-circle"></i> Custom Info Alert: Remember to update your profile regularly.</p>
</div>

5. Interactive Alerts

Add buttons or links inside alerts for additional functionality.

<div class="w3-panel w3-yellow">
  <p><i class="fa fa-warning"></i> Warning: Your trial period is ending soon!</p>
  <a href="#" class="w3-button w3-blue w3-round">Upgrade Now</a>
</div>

6. Stacked Alerts

<div class="w3-panel w3-red">
  <p>Error: File upload failed.</p>

</div>
<script>
  setTimeout(function() {
    document.getElementById('fadeAlert').style.display = 'none';
  }, 3000);
</script>
