For example, you could use a hillshade style layer to render <a href=\"https://www.mapbox.com/help/access-elevation-data/#mapbox-terrain-rgb\">Mapbox Terrain-RGB</a> data.\n\nTo display posterized hillshading based on vector shapes, as with the <a href=\"https://www.mapbox.com/vector-tiles/mapbox-terrain/\">Mapbox Terrain</a> source, use an `MGLVectorTileSource` object in conjunction with several `MGLFillStyleLayer` objects."

If the style’s other layers use the Mapbox Streets source, the background style layer is responsible for drawing land, whereas the oceans and other bodies of water are drawn by `MGLFillStyleLayer` objects.\n\nA background style layer is typically the bottommost layer in a style, because it covers the entire map and can occlude any layers below it. You can therefore access it by getting the last item in the `MGLStyle.layers` array.\n\nIf the background style layer is transparent or omitted from the style, any portion of the map view that does not show another style layer is transparent."
