When clicked, the alert is hidden by setting display: none on the container.

​
Responsive Behavior

The alert has a max-width to prevent it from being too large: 
.alert-content {
  max-width: 400px;
}
On mobile devices, consider adding media queries: 
@media (max-width: 576px) {
  .alert-container {
    bottom: 10px;
    right: 10px;
    left: 10px;
  }
  
  .alert-content {
    max-width: 100%;
    font-size: 0.85rem;
  }
}

​
Customization

​
Making it Reusable

To accept custom message and styling as props:
src/components/Alert.astro
---
interface Props {
  message: string;
  type?: 'info' | 'warning' | 'error' | 'success';
  dismissible?: boolean;
}

const { 
  message, 
  type = 'warning',
  dismissible = true 
} = Astro.props;

const colors = {
  info: '#2196F3',
  warning: '#4caf50',
  error: '#f44336',
  success: '#4caf50'
};

const borderColor = colors[type];
---

<div class="alert-container">
  <div class="alert-content" style={`border-color: ${borderColor}`}>
    {dismissible && (
      <button class="close-button" 
              onclick="this.parentElement.parentElement.style.display='none';">
        ×
      </button>
    )}
    <p class="mb-0" set:html={message} />
  </div>
</div>
Usage: 
<Alert 
  message="<strong>Notice:</strong> Maintenance scheduled for tonight."
  type="info"
  dismissible={true}
/>

​
Persistent Dismissal

To remember the user dismissed the alert using localStorage:
src/components/Alert.astro
<div class="alert-container" id="site-alert">
  <div class="alert-content">
    <button class="close-button" onclick="dismissAlert()">
      ×
    </button>
    <p class="mb-0">
      <span class="warning-text">⚠️ This is not the official website!</span>
      This page was created for educational purposes only.
    </p>
  </div>
</div>

<script>
  function dismissAlert() {
    const alert = document.getElementById('site-alert');
    if (alert) {
      alert.style.display = 'none';
      localStorage.setItem('alertDismissed', 'true');
    }
  }

  // Check if alert was previously dismissed
  if (localStorage.getItem('alertDismissed') === 'true') {
    const alert = document.getElementById('site-alert');
    if (alert) {
      alert.style.display = 'none';
    }
  }
</script>
