HTML Frames
With frames, you can display more than one Web page in the same
browser window.
Examples
Vertical frameset
This example demonstrates how to make a vertical frameset with three different
documents.
Horizontal frameset
This example demonstrates how to make a horizontal frameset with three different
documents.

Frames
With frames, you can display more than one HTML document in the same browser
window. Each HTML document is called a frame, and each frame is independent of
the others.
The disadvantages of using frames are:
- The web developer must keep track of more HTML documents
- It is difficult to print the entire page
The Frameset Tag
- The <frameset> tag defines how to divide the window into frames
- Each frameset defines a set of rows or columns
- The values of the rows/columns indicate the amount of screen area each row/column will
occupy
The Frame Tag
- The <frame> tag defines what HTML document to put into each frame
In the example below we have a frameset with two columns. The first column is
set to 25% of the width of the browser window. The second column is set to 75%
of the width of the browser window. The HTML document "frame_a.htm" is
put into the first column, and the HTML document "frame_b.htm" is put
into the second column:
<frameset cols="25%,75%">
<frame src="frame_a.htm">
<frame src="frame_b.htm">
</frameset>
|
Note: The frameset column size value can also be set in pixels
(cols="200,500"), and one of the columns can be set to use the remaining space
(cols="25%,*").
Basic Notes - Useful Tips
If a frame has visible borders, the user can resize it by dragging
the border. To prevent a user from doing this, you can add noresize="noresize" to
the <frame> tag.
Add the <noframes> tag for browsers that do not
support frames.
Important: You cannot use the <body></body> tags together with the
<frameset></frameset> tags! However, if you add a <noframes> tag containing some
text for browsers that do not support frames, you will have to enclose the text
in <body></body> tags! See how it is done in the first example below.

How to use the <noframes> tag
This example demonstrates how to use the <noframes> tag.
Mixed frameset
This example demonstrates how to make a frameset with three documents, and
how to mix them in rows and columns.
Frameset with noresize="noresize"
This example demonstrates the noresize attribute. The frames are not resizable.
Move the mouse over the borders between the frames and notice that you can not
move the borders.
Navigation frame
This example demonstrates how to make a navigation frame. The navigation frame contains a
list of links with the second frame as the target. The file called "tryhtml_contents.htm"
contains three links. The source code of the links:
<a href ="frame_a.htm" target ="showframe">Frame a</a><br>
<a href ="frame_b.htm" target ="showframe">Frame b</a><br>
<a href ="frame_c.htm" target ="showframe">Frame c</a>
The second frame will show the linked document.
Inline frame
This example demonstrates how to create an inline frame (a frame inside an HTML
page).
Jump to a specified section
within a frame
This example demonstrates two frames. One of the frames has a source to a
specified section in a file. The specified section is made with <a
name="C10"> in the "link.htm" file.
Jump to a specified
section with frame navigation
This example demonstrates two frames. The navigation frame (content.htm) to the left contains a
list of links with the second frame (link.htm) as a target. The second frame shows
the linked document. One of the links in the navigation frame is linked to a
specified section in the target file. The HTML code in the file "content.htm"
looks like this: <a href ="link.htm" target ="showframe">Link without Anchor</a><br><a href
="link.htm#C10" target ="showframe">Link with Anchor</a>.
