Configuring DITA-OT You can adjust DITA Open Toolkit behavior via dita command arguments and options, parameter settings, and configuration properties. Arguments and options for the dita commandThe dita command takes mandatory arguments to process DITA content. Subcommands can be used to manage plug-ins, or print information about the current configuration. A series of options are available to modify the command behavior or specify additional configuration parameters.DITA-OT parametersCertain parameters apply to all DITA-OT transformations. Other parameters are common to the HTML-based transformations. Some parameters apply only to specific transformation types. These parameters can be passed as options to the dita command using the --parameter=value syntax or included in build scripts as Ant properties.Configuration propertiesDITA-OT uses .properties files and internal properties that store configuration settings for the toolkit and its plug-ins. Configuration properties are available to both Ant and Java processes, but unlike argument properties, they cannot be set at run time.Customizing HTML outputYou can modify the look and feel of your HTML output by changing parameter settings to include custom CSS, headers and footers, or table-of-contents navigation in topics.Customizing PDF outputYou can adjust various aspects of PDF output by changing parameter settings or using a theme file.
