If you are using a layer mask to hide portions of a layer, you can apply the mask to discard the hidden portions.
A vector mask creates a sharp-edged shape on a layer and is useful anytime you want to add a design element with
clean, defined edges. After you create a layer with a vector mask, you can apply one or more layer styles to it, edit
them if needed, and instantly have a usable button, panel, or other web-design element.
