Basic Markers

Basic usage

A map needs the GPS coordinates of its center and a zoom level.

Event usage

The stateChange event fires when the map is zoomed or moved, the pointSelect event when a point is clicked. Zoom, drag or click the map.

Shape Usage

The map model can also hold shapes: polylines, polygons, circles and rectangles.

Usage


<style>
    /* the map tiles follow the color scheme of the page (data-dark on html, set by the theme configurator) */
    html[data-dark="true"] .leaflet-tile-pane {
        filter: invert(1) hue-rotate(180deg) brightness(0.95) contrast(0.9);
    }
</style>
