Word And Letter Spacing
Two other proper ties that are often used are word-spacing and letter-
spacing. You can use them to control—you guessed it—the spacing
between words and letters, respectively. Both properties support three
different values that represent optimal, minimum and maximum spacing.
Show & Tell uses letter-spacing on its navigation links.
For word-spacing, setting only one value corresponds to the optimal
spacing (and the other two are set to normal). When setting two values,
the first one corresponds to the optimal and minimum spacing, and the
second to the maximum. Finally, if you set all three values, they correspond
to all three mentioned above. With no justification, optimal spacing is used.
It works slightly different for letter-spacing. One value only
corresponds to all three values. The others work as they do for word-
spacing.
The specifications contain a few requests for more information and
examples on how white-space processing will work and how it can be used
and be useful for languages such as Japanese, Chinese, Thai, Korean, etc.
