Changing the transparency of layers

Changing the transparency, or opacity, of a layer in a web map allows you to see more or less of the underlying layers. The transparency of any layer can be adjusted from 0 percent to 100 percent. The more transparent a layer is, the less visible it appears on the map and the more visible the other layers appear. By default, the basemap is 0 percent transparent (which means it is fully visible, or opaque). If you want to focus attention on the data layers in your map, you might consider making your basemap more transparent. Similarly, you could highlight a specific layer by making it fully visible and adding transparency to the other layers.

To change the transparency of a layer, follow the steps below.
