<img src="image.jpg" lazy="true" lazy-placeholder="placeholder.jpg" />

web-share - Native Sharing API ๐Ÿ“ฑ

Uses Web Share API with smart fallbacks:

<share-button share-title="Amazing Product"
              share-text="Check this out!"
              fallback="copy">Share</share-button>

<button web-share="true" share-title="Quick Share" fallback="twitter">

     observe-enter-class="fade-in-up"
     observe-once="true">
    Animates when scrolled into view
</div>

pwa-install - PWA Installation ๐Ÿ“ฒ

Progressive Web App installation prompts:

<pwa-install install-text="Install Our App"
             auto-prompt="true"
             auto-prompt-delay="5000">
    Install App
</pwa-install>

asp-auto-hide - Automatic Element Hiding ๐ŸŽญ

Automatically hide elements after a specified delay with smooth animations:

<!-- Auto-hide alert after 5 seconds -->
<alert alert-type="success" 
       asp-auto-hide="true"
       asp-auto-hide-delay="5"
       asp-auto-hide-effect="fade">
    Operation completed successfully!
</alert>

<!-- Custom auto-hide component with slide effect -->
<asp-auto-hide asp-auto-hide-delay="10" 
               asp-auto-hide-effect="slide-up"
               asp-auto-hide-debug="true"
               class="bg-blue-50 border border-blue-200 text-blue-800 p-4 rounded-lg">
    This notification will slide up and disappear in 10 seconds.
    Hover to pause the timer.
</asp-auto-hide>

<!-- Auto-hide with pause on hover -->
<div asp-auto-hide="true" 
     asp-auto-hide-delay="8"
     asp-auto-hide-pause-on=".notification-area"
     class="fixed top-4 right-4 bg-green-500 text-white p-4 rounded-lg shadow-lg">

     asp-auto-hide-duration="500"
     asp-auto-hide-remove="true"

     id="custom-notification"
     class="transform transition-all duration-500 bg-indigo-100 border border-indigo-300 text-indigo-800 p-4 rounded-lg">
    This element will be completely removed from DOM.
    <button onclick="window.autoHide_custom_notification.start()" 
            class="ml-2 px-2 py-1 bg-indigo-200 rounded text-xs">
        Start Timer
    </button>
</div>

JavaScript API for Programmatic Control:

// Access the auto-hide controls
const controls = window.autoHide_[elementId];

// Start or restart the timer
controls.start();

// Hide immediately with animation
controls.hide();

// Cancel the timer
controls.cancel();
