12.5. Inline (Floating) FramesMicrosoft Internet Explorer 3.0 introduced a feature called inline frames (also called floating frames ) that are identified with the iframe element. They enable an HTML document to be embedded within another HTML document, viewed in a scrollable frame. An iframe is placed in the document flow as an inline element, much like an image.

The iframe element is part of the HTML 4.01 and XHTML 1.0 Transitional DTD. As such, it is also included in the Frameset DTD, but it is not a frameset-related element. It is supported by standards-compliant browsers. It is however deprecated, and the preferred strict alternative is to use the object element instead, its type attribute explicitly set to text/html, and its data attribute set to the URL of the external document. Inline frames do not work in Netscape 4, but that accounts for a less than .5% of users as of this writing. The iframe element places an external HTML document on a web page in a scrolling window. The src attribute provides the URL of the external document. The width and height attributes provide the dimensions of the floating frame. Figure 12-10 shows the resulting inline frame specified in this markup example. <body bgcolor="black" text="white"> <h1>Inline (Floating) Frames</h1> <p><iframe src="/books/4/439/1/html/2/list.html" width="200" height="100" align="left"> Your browser does not support inline frames. Read the list <a href="list. html">here</a>.</iframe></p> <p>Consectetuer adipiscing elit. Sed eu nibh eget magna dictum egestas... </p> </body> Figure 12-10. Inline (floating) frame |
