FRAMES

It is used to divide the browser window into several parts through which we can see more than one web page at a time.

Each HTML document is called frame.

To create frames tags used are:

<frame>

E.g.

<HTML>

<HEAD>

<TITLE>frame example</TITLE>

</HEAD>

</frameset>

</HTML>

About <frameset> tag

<frameset> tag is a container tag for defining frames.
It replaces the <body> tag in frameset documents
It defines how to divide the window into frames.
Each frameset defines a set of rows or columns.
To divide screen horizontally we use rows.
To divide screen vertically we use cols
The rows/cols values indicate the amount of screen area, each row/column will occupy

Attributes of frameset tag

i) Rows - It divides the screen into horizontal frames.

ii) Cols - It divides the screen into vertical frames.

Values of area can be given in % or pixels or by relative value using * (asterisk) symbol.

<noframes> tag

The <noframes> tag is a fallback tag for browsers that do not support frames. It can contain all the HTML elements that you can find inside the <body> element of a normal HTML page.

The <noframes> element can be used to link to a non-frameset version of the web site or to display a message to users that frames are required.

The <noframes> element goes inside the <frameset> element.

<html>

<head>
