DevGuru HTML Tag: iframe


			TAG: iframe
			<iframe> ... </iframe> Available in versions: 4.0 Browser compatibility: Explorer 4, 5 Netscape 6 The <iframe> tag is used to insert an inline frame into the body of an HTML document. This is a very convenient method for inserting an HTML page inside another HTML page. Unlike the frameset, frame, and noframes tags, the iframe tag can only be used inside a body element. You must not place the iframe tag inside a frameset element. An iframe 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 an iframe is to assign a URL using the src attribute. Whatever content is displayable at the referenced URL will in turn be displayed inside the iframe. You can place a default textual message between the opening and closing iframes tags. This will only display if the browser does not recognize inline frames. The closing tag is mandatory. Core Attributes class id style title Attributes align The align attribute is used to place the frame inline with adjacent text. The values bottom, middle, and top align the frame with the bottom, middle, and top of the text. The values right and left place the text on the right or left boundary and allow any text to flow around the frame. frameborder The frameborder attribute is used to add or remove a border around the frame. The values of yes or 1 allow a border. The values of no or 0 forbid a border. height The height attribute sets the vertical extent of the iframe in either pixels or as a percentage of the overall screen height. 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. scrolling The scrolling attribute is used to determine if horizontal and vertical scrolling bars will appear in the iframe. 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. width The width attribute sets the horizontal extent of the iframe in either pixels or as a percentage of the overall screen width. Code: <iframe width="50%" height="77" src="html_frames_yellow_two.html" frameborder="yes" scrolling="yes"> Sorry, you need inline frames to fully see this page. </iframe> Output: Sorry, you need inline frames to fully see this page.
