## Definition and Usage

The <frameset> tag defines a frameset.

The frameset element holds two or more frame elements. Each frame element holds a separate document.

The frameset element states only how many columns or rows there will be in the frameset.

## Browser Support

The <frameset> tag is supported in all major browsers.

## Differences Between HTML and XHTML

NONE

## Tips and Notes

Note: If you want to validate a page containing frames, be sure the doctype is set to "Frameset DTD". Read more about doctypes.

Important: You cannot use the body element together with the frameset element. 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 a body element.

Navigation frame
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
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>.
