Rather than specify fonts for web pages,
it is good practice to specify Font Families so that reasonable fonts
are presented, no matter what fonts are on a user's computer.
Not all browsers display text the same way. You will want to test your results on all common browsers.
To set the font, enter the
name of the font you want, such as Arial, FranklinGothic, or Helvetica. In
addition, you can specify a generic font such as serif, sans-serif, cursive,
fantasy, or monospace. You can list choices, separated by commas; the browser
will attempt to provide the first choice if it exists on the
computer, then will try the second choice, and so on. Put the generic font
last.
For example, in the Stylesheet:
<xsl:variable name=
"global_font">verdana,sans-serif</xsl:variable>
