Also note that you don't need a connection to the Internet or
the World Wide Web to write and view your HTML or XHTML documents.
You may compose and view your documents stored on a hard drive or
floppy disk that's attached to your computer. You can even
navigate among your local documents with the languages'
hyperlinking capabilities without ever being connected to the
Internet, or any other network, for that matter. In fact, we
recommend that you work locally to develop and thoroughly test your
documents before you share them with others.
We strongly recommend, however, that you do get
a connection to the Internet if you are serious about composing your
own documents. You may download and view others' interesting
web pages and see how they accomplished some interesting
feature -- good or bad. Learning by example is fun, too. (Reusing
others' work, on the other hand, is often questionable, if not
downright illegal.) An Internet connection is essential if you
include in your work hyperlinks to other documents on the Internet.
