With frames, several Web pages can be displayed in the same browser window.
ATTENTION. Do not expect frames to be supported in future versions of HTML.

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:
- Frames are not expected to be supported in future versions of HTML
- Frames are difficult to use. (Printing the entire page is difficult).
- The web developer must keep track of more HTML documents
The HTML frameset Element
The frameset element holds one or more frame elements. Each frame element can hold a separate document.
The frameset element states HOW MANY columns or rows there will be in the frameset, and HOW MUCH percentage/pixels of space will occupy each of them.
The HTML frame Element
The <frame> tag defines one particular window (frame) within a frameset.
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 document "frame_a.htm" is put into the first column, and the document "frame_b.htm" is put into the second column:
<frame src="frame_a.htm" />
<frame src="frame_b.htm" />
Note: The frameset column size can also be set in pixels (cols="200,500"), and one of the columns can be set to use the remaining space, with an asterisk (cols="25%,*").
Basic Notes - Useful Tips
Tip: 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.
Note: 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
How to use the <noframes> tag (for browsers that do not support frames).
How to create a frameset with three documents, and how to mix them in rows and columns.
Frameset with noresize="noresize"
How to use the noresize attribute. Move the mouse over the borders between the frames and notice that you cannot move the borders.
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.
Jump to a specified section within a frame
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
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>.
