The first configuration element css removes CSS style sheet named "Visible inclusions and locations" from the menu.
The second one replaces the default CSS style sheet for DocBook (named "DocBook", see ) by a customized one.XXE_install_dir/addon/config/docbook/docbook.xxe
<!-- Discard this CSS --> <css name="Visible inclusions and locations"/> <!-- Customize the normal CSS --> <css name="DocBook" location="mydocbook.css" />
The customized CSS style sheet imports the normal DocBook CSS style sheet using standard construct @import (but with special URI starting with "xxe-config:") and customizes the look and feel of DocBook element link.
@import url(xxe-config:docbook/css/docbook.css);
link:after {
content: set-attribute-button(attribute, linkend,
icon, icon(right));
color: rgb(128,128,196);
}
