DevGuru HTML Tag: frame


			TAG: frame
			<frame ... > Available in versions: 4.0 Browser compatibility: Explorer 4, 5 Netscape 4, 6 The <frame> tag is used to create one frame, which is simply a window within another window. As an example, if you want three frames (windows) to appear on an HTML page, you must have three frame tags and the frameset element must set the spacing for three frames. The frame tags can only occur between an opening and closing frameset element. A frame element displays content, including forms, images, multimedia, other frames, tables, etc. It is very important to understand that the only way to assign content to a frame is to assign a URL using the src attribute. Whatever content is displayable at the referenced URL will in turn be displayed inside the frame. The frames can have either a column (vertical) or a row (horizontal) configuration, but not both. The configuration must be set using either the cols or the rows attribute of the frameset tag, but not both. The order of the frame tags sets the order of the frames. If they are in a rows configuration, the first frame element is the top window, the second frame element is second from the top, etc. For the cols configuration, the order is left to right. Note that you can nest frameset tags inside of frameset tags. Therefore, an HTML document can contain numerous frames. This opens the possibility of creating complex and imaginative page displays (however, always remember to keep the page user friendly). Core Attributes class id style title Attributes frameborder The frameborder attribute is used to add or remove a border around a frame. The value of yes or 1 allows a border. The value of no or 0 forbids a border. longdesc The longdesc attribute is the URL address of an HTML document that contains a long textual description of the frame. This is designed to provide more information than a title element would display. marginheight The marginheight attribute is used to set the amount of white space in pixels that will appear along the top and bottom margins between the frame border and the contents. If you provide an unrealistic value, the browser will simply ignore this attribute. marginwidth The marginwidth attribute is used to set the amount of white space in pixels that will appear along the left and right margins between the frame border and the contents. If you provide an unrealistic value, the browser will simply ignore this attribute. name The name attribute is a string of characters that is used to label a frame with a name. The name must be unique to that document and cannot be reused. noresize The noresize attribute prevents the user from changing the frame size. scrolling The scrolling attribute is used to determine if horizontal and vertical scrolling bars will appear in the frame. If the content is larger than the frame, this permits scrolling up and down or left and right, as needed, to see the entire contents. There are three permitted values: yes which always displays scroll bars; no which never displays scroll bars; and auto which displays scroll bars only when needed. If a value is not provided, the default is auto. src The src attribute provides the URL address of any valid HTML, ASP, or other displayable page. The contents of the referenced URL will be displayed inside the frame. This example creates five frames, each with a different background color. Note that there is no body tag. Code: <html> <head> <title>frames example</title> </head> <frameset cols="50%, 50%"> <noframes> To be viewed properly, this page requires frames. </noframes> <frameset rows="33%, 33%, *"> <frame src="html_frames_red.html"> <frame src="html_frames_orange.html"> <frame src="html_frames_yellow.html"> </frameset> <frameset rows="50%, 50%"> <frame src="html_frames_green.html"> <frame src="html_frames_blue.html"> </frameset> </frameset> </html> Output: Click here to see the output of this frames example in a separate window.
