rowsAttribute. The rowsattribute specifies how the window will be divided verti-

cally into rows of pixels (think of it as forming one row under another across the

screen). The value can be a percentage of the browser window, a number of pixels, or

the special asterisk value (*). The special asterisk value tells the browser to calculate the

appropriate space for the window. A value is given for each frame row. There can be

multiple frames. For example, to create a frameset with two horizontal frames—one

using 25 percent of the window and the other using what is left of the window—the

code is <frameset rows="25%,*">.

colsAttribute. The colsattribute specifies how the window will be divided hori-

zontally into columns of pixels (think of it as forming one column next to another

across the screen). The value can be a percentage of the browser window, a number of

pixels, or the special asterisk value (*). The special asterisk value tells the browser to

calculate the appropriate space for the window. A value is given for each frame column.

There can be multiple frames. For example, to create a frameset with two vertical

frames—one using 200 pixels of the window and the other using what is left of the

window—the code is <frameset cols="200,*">.

The <frame />Ta g

tained within a frameset. Table A.22 shows <frame />tag attributes and their values.

The <noframes>tag configures what will display on browsers and other user agents

that don’t support frames.
