HTML <frameset> Tag
The <frameset> tag defines the structure of a frame, number of columns and rows and its place in a window. Tag description, attributes, using examples.
The <frameset> tag defines the structure of a frame (a zone in the browser window where another web page can be loaded), the number of columns and rows, and their respective sizes in pixels or percentages.
The <frameset> and <frame> tags are deprecated HTML tags.
You can use the <iframe> or <div> tags with different CSS properties for getting the same result.
The pages that contain frames can be validated only if the <!DOCTYPE> is set to XHTML Frameset DTD or HTML Frameset DTD.
Syntax
The <frameset> tag comes in pairs. The content is written between the opening (<frameset>) and closing (</frameset>) tags.
The <frameset> tag can contain one or several <frame> tags. It is allowed to nest one <frameset> tag in another if it is necessary to divide the windows into smaller ones.
The frameset document uses the <frameset> element instead of the <body> element. The frameset element may not contain any content, but instead it defines and names frames arranged in rows and/or columns.
Example of the HTML <frameset> tag:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<title>Title of the document</title>
