Inline elements such as emphasis can be customized by replacing their templates in a customization layer. See the section “Replacing templates” for a description of the general method. The templates to be customized can be found in fo/inline.xsl for FO output.

Many of the templates for inline elements call one of the following named templates to change font. These template names are also used in the HTML stylesheets.

Customizing inline elements that use these templates may mean just calling a different template. For example, this customization changes the font for the filename element from the default monospace to italic:

<xsl:template match="filename">
  <xsl:call-template name="inline.italicseq"/>
</xsl:template>

You can also add templates with more specific match attributes to further customize elements. For example, the filename element can also be used for directory names. You might use the class attribute to distinguish directory names, and then add a custom template to format them in boldface:

<xsl:template  match="filename[@class='directory']">
  <xsl:call-template  name="inline.boldseq"/>
</xsl:template>

The @class='directory' predicate means this template will only be considered for use on filename elements that have a class="directory" attribute. Its match attribute is more specific than the regular filename template, so it has precedence when that role value is used.

If you want to select a font family that is different from the body font, then you need to customize the template a bit further. See the section “Line annotations” for an example of customizing the font used for the lineannotation element.

<xsl:attribute-set name="superscript.properties">
  <xsl:attribute name="font-size">60%</xsl:attribute>
  <xsl:attribute name="font-family">serif</xsl:attribute>
</xsl:attribute-set>
