You have been asked to give a
presentation at a conference.  Your
visual presentation is in the form of a
website that is projected onto a
screen.  You are also quite sure that
some of those present will want a
printed copy of the document.  You want
to create a presentation that is
projected with Arial font, colourful
headings and a largish font size.  But,
for the print version, you would rather
the material be optimized for black ink
and in a serif (Times New Roman) font
at a suitable size for print (10/12
points).  Please create a stylesheet
that would accomplish this.

>>

 @media screen
  { 
  p { font-size: 12px;
  color: blue;
  background: white;
  font-family: "Comic Sans Ms", cursive;
  }
  }

  @media print
  { 
  p { font-size: 12pt;
  color: black;
  background: white;
  font-family: "Times New Roman", serif;
  }
  }

  @media projection
  {
  p { font-size: 30pt;
  color: red;
  background: white;
  font-family: Arial, Helvetica, sans-
serif; 
  }

H1 {color:blue;background:transparent;}
H2 {color:green;
background:transparent;}
H3
{color:yellow;background:transparent;}
  }



You are creating an instructional
website.  There is a strong possibility
that several people accessing your site
are sight-impaired.  What strategy
could you use - assuming that they will
be using a screen reader?

Use the @media technique to provide
alternatives. Page 363 gives examples
such as @media braille, @media
embossed, and @media aural. Using the
@media aural would be good for a screen
reader. With this technique, you can
set elements such as volume, type of
voice heard, azimuth, and pitch. This
page has some good examples:
