Aside from helping you control the underlying coding method for producing AP elements, Dreamweaver
enables you to define the default AP element. An AP element is a page element, often a
tag that is
absolutely positioned. This capability is especially useful during a major production effort in which the Web
development team must produce hundreds of AP elements spread over a Web site. Being able to specify in
advance the initial size, color, background, and visibility saves numerous steps??”each of which would have
to be repeated for every AP element. Figure 4-11 shows the layout of the AP Elements category of the
Preferences dialog box. The controls accessible through the AP Elements category are described in the following
sections.
FIGURE 4-11
In the AP Elements category of Preferences, you can predetermine the structure of the default Dreamweaver AP element.
Visibility option
AP elements can be either visible or hidden when the Web page is first loaded. An AP element created using
the default visibility option is always displayed initially; however, no specific information is written into the
code. Selecting Visible forces Dreamweaver to include a visibility:visible line in your AP element
code. Likewise, if you select Hidden from the Visibility options, the AP element is initially hidden.
