Inline Frames
The main advantage of inline frames is that is that you can position them anywhere on a
web page, just as you can other elements like images or Flash movies. You can incorpo-
rate content from another page or even another site into a page in a seamless way
through the use of inline frames. Inline frames, which are specified using the <iframe>
tag, are commonly the means by which “widgets” offered by popular websites are incor-
porated into other websites. For example, sites like Twitter and Facebook offer widgets
that you can incorporate into your own site that are implemented using inline frames.
Here's a brief run-through of how to create floating frames. First, you define them using
the <iframe> tag. Like images, these frames appear inline in the middle of the body of
an HTML document (hence the i for inline). The <iframe> tag supports attributes like
src , which contains the URL of the document to be displayed in the frame, and height
and width , which control the size of the frame.
Table 17.3 lists the attributes of the <iframe> element.
