Plug-ins are
applications that allow you to use file-types that aren't supported by
your browser, like VRML, Shockwave, RealVideo and many more. I will not
explain here how to make these file types, as it is a long and complicated
procedure and usually requires expensive software. I will explain how to
embed these file types in your page if you have them.
But first some easier stuff. How would you like to add a background
song to your page? It can be repeated infinitely or a specific number of
times. The tag is this:
<bgsound src="example.wav"
loop="4">
The number you put in the loop attribute is the number of times the
sound will repeat itself. You may also put "-1" to make it loop
forever.
