AI-generated Key Takeaways
-
This example demonstrates how to style a Google Map in night mode using a JSON styles array to change the color of map elements.
-
The night mode style is suitable for dark environments and improves visibility for giving directions or navigating in low-light conditions.
-
The provided code snippets include TypeScript, JavaScript, CSS, and HTML to implement and display the styled map.
-
While the styling affects roads, labels, and other map components, it does not change the base imagery in satellite view.
This example styles the map in night mode. It uses colors that are useful for situations such as giving directions in the dark. In the satellite view, styling does not affect base imagery, but it does affect roads, labels, and other map components.

TypeScript
function initMap(): void { // Styles a map in night mode. const map = new google.maps.Map( document.getElementById("map") as HTMLElement, { center: { lat: 40.674, lng: -73.945 }, zoom: 12, styles: [ { elementType: "geometry", stylers: [{ color: "#242f3e" }] }, { elementType: "labels.text.stroke", stylers: [{ color: "#242f3e" }] }, { elementType: "labels.text.fill", stylers: [{ color: "#746855" }] }, { featureType: "administrative.locality", elementType: "labels.text.fill", stylers: [{ color: "#d59563" }], }, { featureType: "poi", elementType: "labels.text.fill", stylers: [{ color: "#d59563" }], }, { featureType: "poi.park", elementType: "geometry", stylers: [{ color: "#263c3f" }], }, { featureType: "poi.park", elementType: "labels.text.fill", stylers: [{ color: "#6b9a76" }], }, { featureType: "road", elementType: "geometry", stylers: [{ color: "#38414e" }], }, { featureType: "road", elementType: "geometry.stroke", stylers: [{ color: "#212a37" }], }, { featureType: "road", elementType: "labels.text.fill", stylers: [{ color: "#9ca5b3" }], }, { featureType: "road.highway", elementType: "geometry", stylers: [{ color: "#746855" }], }, { featureType: "road.highway", elementType: "geometry.stroke", stylers: [{ color: "#1f2835" }], }, { featureType: "road.highway", elementType: "labels.text.fill", stylers: [{ color: "#f3d19c" }], }, { featureType: "transit", elementType: "geometry", stylers: [{ color: "#2f3948" }], }, { featureType: "transit.station", elementType: "labels.text.fill", stylers: [{ color: "#d59563" }], }, { featureType: "water", elementType: "geometry", stylers: [{ color: "#17263c" }], }, { featureType: "water", elementType: "labels.text.fill", stylers: [{ color: "#515c6d" }], }, { featureType: "water", elementType: "labels.text.stroke", stylers: [{ color: "#17263c" }], }, ], } ); } declare global { interface Window { initMap: () => void; } } window.initMap = initMap;
JavaScript
