In-Depth Information
of the frames. The
rows
and
cols
attributes of each frameset specify how much room the
frame will need within the window. These values use exact pixels as a default, although
you can also use percentages to represent a section of the window, or an asterisk * to
allocate leftover space. (These size values will be shown in Examples 10.15 and 10.16.)
Creating HTML Frames.
In Example 10.14 the window is divided into two frames:
a left frame that takes up 25 percent (in columns) of the window and a right frame that
takes up 75 percent (in columns) of the rest of the window. Because files are required to
accomplish this, the main file defines the frameset, the second file contains the HTML
code for the left frame, and the third file contains the HTML code for the right frame.
