About layer clipping masks
A clipping mask is a group of layers to which a mask is applied. The bottommost layer, or base layer, defines the visible
boundaries of the entire group. For example, sometimes you have a shape in the base layer, a photograph in the layer
above it, and text in the topmost layer. If you group them, the photograph and text appear only through the shape
outline in the base layer. They also take on the opacity of the base layer.

You can group only successive layers. The name of the base layer in the group is underlined, and the thumbnails for
the overlying layers are indented. Additionally, the overlying layers display the clipping mask icon

You can link the layers in a clipping mask so that they move together.
The shape in the bottom layer of the clipping mask determines what area of the photo layer above shows through.

The layers in the clipping mask have the opacity and mode attributes of the bottommost base layer in the group.
To change the stacking order of the clipping mask relative to other layers in the image, select all layers in the group.
Then drag the group’s base layer up or down in the Layers panel. (Dragging a layer without selecting all the layers in
