<para>The <parameter>docbook.css.source</parameter> parameter
specifies the name of the file containing the default DocBook
CSS styles. Those styles are necessary when the
<parameter>make.clean.html</parameter> parameter is nonzero.</para>
<para>The file is a well-formed XML file that
must consist of a single <tag>style</tag> root
element that contains CSS styles as its text content.
The default value of the parameter (and filename)
is <literal>docbook.css.xml</literal>.
The stylesheets ship with the default file. You can substitute
your own and specify its path in this parameter.</para>
<para>If <parameter>docbook.css.source</parameter> is not blank,
and <parameter>make.clean.html</parameter> is nonzero, then
the stylesheet takes the following actions:</para>
<orderedlist>
<listitem>
<para>The stylesheet uses the XSLT <literal>document()</literal>
function to open the file specified by the parameter and
load it into a variable.</para>
</listitem>
<listitem>
<para>The stylesheet forms an output pathname consisting of the
value of the <parameter>base.dir</parameter> parameter (if it is set)
and the value of <parameter>docbook.css.source</parameter>,
with the <literal>.xml</literal> suffix stripped off.
</para>
</listitem>
<listitem>
<para>The stylesheet removes the <tag>style</tag>
wrapper element and writes just the CSS text content to the output file.</para>
</listitem>
<listitem>
<para>The stylesheet adds a <tag>link</tag> element to the
HTML <tag>HEAD</tag> element to reference the external CSS stylesheet.
For example:</para>
<programlisting><link rel="stylesheet" href="docbook.css" type="text/css">
</programlisting>
<para>However, if the <parameter>docbook.css.link</parameter>
parameter is set to zero, then no <tag>link</tag> is written
for the default CSS file. That is useful if a custom
CSS file will import the default CSS stylesheet to ensure
proper cascading of styles.</para>
</listitem>
</orderedlist>
<para>If the <parameter>docbook.css.source</parameter> parameter
is changed from its default <literal>docbook.css.xml</literal> to blank,
then no default CSS is generated. Likewise if the
<parameter>make.clean.html</parameter> parameter is set to zero,
then no default CSS is generated. The
<parameter>custom.css.source</parameter> parameter can be used
instead to generate a complete custom CSS file.</para>
<para>You can use the <parameter>generate.css.header</parameter>
parameter to instead write the CSS to each HTML <tag>HEAD</tag>
element in a <tag>style</tag> tag instead of an external CSS file.</para>
