Putting all of the above together, you begin to see that a sophisticated presentation can be created simply. Keep in mind that an HTML file is merely a text file with special markers before and after any point in the text that you wish to place your link. The link is nothing more than the name of another text, graphic, sound, or movie file on your system or on a remote system to which you connect via a proper Internet address. If you have advanced skills, the file can even be an executable program written in any number of languages, including shell scripts. There's an extra bonus in all of this.
Most browsers intended for Internet surfing can display HTML pages offline as well.
By simply telling the browser that you are loading a local page, it will look on your own computer's directories for the requested f iles. The beauty of this feature is not only that you can pretest presentations that you intend to place onli ne and that your preview is at the full speed of your machine's processor rather than the modem connection speed, but that it's also possible to create presentations for offline viewing. My experience has shown that although this method lacks pizzazz and effects such as flying titles that you might find in advanced presentation software, it is nonetheless a quick, easy, and reliable way to create fairly universally viewable presentations that will run on any platform. What I like best about this method of creating interactive presentations is their instant portability to the Internet. The presentation you create locally will run globally.
