14.4 Summary
Although the first stage of the Web's development
was primarily visual in nature, the need to provide web content in
other media led to the introduction of medium-specific styling in
CSS. The ability to take the same document and customize its
presentation in a manner best suited to different output media is
deeply powerful. Although the most common use for this power will be
to create "printer-friendly" styles
for documents, we've also seen how projection styles
can be used to create slideshows with Opera.
While aural styles would be very useful for blind users, as of this
writing, there are only two programs that support even a fragment of
this portion of CSS, and the media type aural
defined in CSS2.x will not be carried forward to future versions of
CSS. Instead, the media type speech has been set
aside for future work in auditory rendering of documents.
