Framed Pages

There are four classes unique to building framed pages.

os_framed_page -If you want to include a frame on a Web page, you must declare the page using os_framed_page . Every os_framed_page contains exactly one os_frameset .
os_frameset -Partitions a single view area into multiple view areas, organized as either rows or columns. You can specify the space allocated to a view area in a frameset in one of the following ways. Different size specification methods can be used within the same frameset.

An absolute, fixed number of pixels.
Percentage of the view area. The total of all view areas combined must equal 100%. If the total is more than 100%, all areas are equally decreased until they equal 100%. If the total is less than 100%, all areas are equally increased until they equal 100%, unless one or more relative areas is also declared. Then, all remaining area is allocated to the relative areas.
Relative to other view areas. All remaining space after allocating fixed pixel and percentage partitions is divided among relative-sized view areas. An asterisk (*) is used to denote relative size viewing area. A single * character is relative in size to the other frames and takes all remaining space. If you declare multiple relative view areas, an integer before the asterisk weighs the space allocations.

A partitioned area within an os_framset can contain another os_frameset or os_frame .

os_frame -Specifies the URL to display in the partition.
os_noframes -Declares content within a frameset for browsers that do not support frames. This class is useful for specifying alternative content for viewers using browsers that do not support frames.
