Dynamic Styling Based on Zoom Levels in mapml-viewer

This experiment demonstrates the dynamic styling capabilities of the mapml-viewer custom element, where the appearance of map features adapts based on the current zoom level. Using a custom matchMedia API, the zoom level is determined programmatically, simulating the behavior of the CSS @media rule to provide responsive and interactive styling.

The custom matchMedia API works similarly to @media in CSS because it evaluates conditions dynamically. Instead of checking device properties like screen width or orientation, it evaluates the zoom level of the map. When a zoom level condition is met, the corresponding styles are applied to map features, creating a responsive and adaptive visualization experience.

The implementation uses a predefined color mapping that associates each zoom level (1 to 18) with a specific hex color. Whenever the zoom level changes, the map-style element is dynamically updated with the corresponding styling, ensuring a seamless and visually engaging user experience.

How to Interact with the Map

• Zoom In/Out:
  • Use the zoom controls on the map interface to change the zoom level.
  • The feature color will dynamically update based on the current zoom level.
