As depicted in Figure 4.2, the top bar is a subarea that exists within the header. At the left-most side of the top bar is the logo for IGWEB. Besides having an obvious function for branding purposes, the logo also serves as a navigational component, since when the user clicks on it, they will be returned to the home page. At the right-most side of the top bar are ancillary user controls to activate specific functionality—the shopping cart and the live chat feature.
