    2. Key Features of This Interactive Map:

    1. Map Container and Image:
      • The .map-container holds the map image and interactive regions.
      • You can replace the placeholder map with an SVG or an actual map image.
    2. Interactive Regions:
      • Each region (.region-1, .region-2, .region-3) is styled with absolute positioning, simulating different parts of the map.
      • You can adjust the top, left, width, and height values to fit your map layout.
    3. Hover Effects:
      • When hovering over a region, the background color changes, and the region grows slightly with transform: scale(1.1).
      • The regions transition smoothly due to the transition: background-color 0.3s ease, transform 0.3s ease.
    4. Popup Information:
      • When hovering over a region, a tooltip with detailed information (data-info) appears, floating above the region. The tooltip fades in and moves upward slightly with transform: translateY(-10px).
    5. Animation for Highlighting a Region:
      • The .region-1 area animates continuously with a color pulsing effect using the @keyframes animation.
    6. No JavaScript Required:
      • This interactive map is purely CSS-driven. The hover states, transitions, and keyframe animations are all handled with CSS.
    7. Customizability:
      • You can easily add more regions by defining new .region classes and positioning them appropriately on the map.
      • For an SVG map, each region can be mapped directly to SVG paths and styled similarly.

    This CSS-only interactive map is a great way to provide basic interactivity and a sleek design without using JavaScript. It can be further enhanced with additional CSS animations and effects.
