demo: OBJECT-tag

Previous slide Next slide Back to first slide View graphic version


OBJECT-tags do not only provide a generic mechanism to include virtually everything in a web document, but they can also be nested. browsers are supposed to start rendering with the outher most OBJECT. if they don't know how to process it, they should try the next OBJECT and so forth. as an example, an author could define something like:

<OBJECT a movie>
   <OBJECT an animated picture>
      <OBJECT an image>text</OBJECT>

the smartest of all browsers would play the movie, a less smart browser would display the animated picture, a simple graphical browser would show the image and a non-graphical browser would render the text.
