<para>
A style sheet consists of optional definitions for system-generated
number tokens, followed by sets of element path statements and their
formatting specifications. To create a style sheet for use with
the Information Manager, follow these steps:
</para>
<orderedlist>
<listitem>
<para>
Open a new file, using a text editor such as <literal>vi</literal> or
<literal>emacs</literal>, or an SGML editor.
</para>
</listitem>
<listitem>
<para>
In the file, identify the style sheet name by giving
a value to the Name attribute of the StyleSheet element. For example:
</para>
<literallayout>
&lt;StyleSheet name=<replaceable>sty1</replaceable>>
</literallayout>
<para>
This name must be unique across style sheets in a bookcase.
</para>
</listitem>
<listitem>
<para>
If you plan to use the <systemitem>AutoNumber</systemitem>
feature, create an autonumber for each token stream. System-generated
number tokens can be used only with the Prefix and Suffix features. For example:
</para>
<literallayout>
&lt;AutoNumber id=num0  reset=enumeratedlist  counter=numitem  type=ucroman  initial="1">
&lt;AutoNumber id=num1  reset=enumeratedlist  counter=numitem  type=lcroman  initial="1">
&lt;AutoNumber id=num2  reset=enumeratedlist  counter=numitem  type=arabic  initial="1">
</literallayout>
<para>
For more information on using the autonumber feature, see AutoNumbers in the
<filename>dtinfoStyle.dtd(5)</filename> man page.
</para>
</listitem>
<listitem>
<para>
Using an element <systemitem>Path</systemitem>
statement, specify the path to the element for which you are defining
the style. <systemitem>Path</systemitem> statements
are read left to right, parent element to child element. You need
only specify the minimum unique path to any given element. This
example specifies the path to the LITERALLAYOUT element:
</para>
<literallayout>
&lt;Path>LITERALLAYOUT&lt;/Path>
</literallayout>
</listitem>
<listitem>
<para>
For each <systemitem>Path</systemitem>
you must specify either the <systemitem>Online</systemitem>
feature set or the <systemitem>Print</systemitem>
feature set, or both. To specify both, you must define the on-line
features first. For example:
</para>
<literallayout>
&lt;Path>
LITERALLAYOUT&lt;/Path>
&lt;Online>
   &lt;Font fallback=mono>
   &lt;Family name=courier weight=medium size=12 charset=iso8859-1>
   &lt;Layout flow=verbatim lindent=12 aspace=6 bspace=6>
   &lt;LineBreak both>
&lt;/Online>
&lt;Print>
   &lt;Font fallback=mono>
   &lt;Family name=courier weight=medium size=12 charset=iso8859-1>
   &lt;Layout flow=verbatim lindent=12 aspace=6 bspace=6>
   &lt;LineBreak both>
&lt;/Print>
</literallayout>
<note>
<para>
The <systemitem>Print</systemitem>
and <systemitem>Online</systemitem> feature sets
match in function, description, and specification except for two
print-specific exceptions: <link linkend="n4kpipbbc3h9x3cs">Medium</link> and
<link linkend="r74dmncp70hp2ol">PageBreak</link>.
</para>
</note>
</listitem>
<listitem>
<para>
Repeat steps 4 and 5 for each element <systemitem>Path</systemitem> for which you want to specify
a particular style.
</para>
</listitem>
</orderedlist>

<title id="pt3bmncx60hp2ol">Font Inheritance</title>
<para>
The <systemitem>Font</systemitem> feature
is <link linkend="pgqaykbbgsg24ak">inherited</link>. Inheritance
determines the set of fonts and font characteristics that will be
applied to inheriting elements. To mask out a font face, both the
font <systemitem>Family</systemitem> feature and
the <systemitem>Charset</systemitem> attribute
must be set. Masking occurs because of the <systemitem>Charset</systemitem>
attribute.
</para>
<para>
To change an element's inherited font characteristics, you
need only change the appropriate <systemitem>Font</systemitem>
feature, not the complete <systemitem>Font/Family</systemitem>
specification. For example:
</para>
<literallayout>
&lt;Font Weight=bold>
</literallayout>

would be sufficient to change an inherited characteristic
for a given element.
