The Frames panel provides a visual representation of the frames within a frameset. It shows the hierarchy of the frameset structure in a way that may not be apparent in the Document window. In the Frames panel, a very thick border surrounds each frameset; each frame is surrounded by a thin gray line and is identified by a frame name.
A selection outline appears around the frame in both the Frames panel and the Document windows Design view.
