Text labels with DivIcon

DivIcon allows you to add text directly on the map using an HTML div element. This is useful when you want a visible label at a specific location, without relying on tooltips or popups that only appear on interaction.

m = folium.Map(location=[41, -71], zoom_start=6)

folium.Marker(
    location=[41, -71],
    icon=folium.DivIcon(
        html='<div style="font-size: 14px; color: black; font-weight: bold;">New York</div>',
        icon_size=(100, 36),
        icon_anchor=(50, 18),
    ),
).add_to(m)

folium.Marker(
    location=[42.36, -71.06],
    icon=folium.DivIcon(
        html='<div style="font-size: 12px; color: navy;">Boston</div>',
        icon_size=(80, 30),
        icon_anchor=(40, 15),
    ),
).add_to(m)
