How can I customize dita output?

Here's part of my post at

It should help you get started.

Regarding changing fonts, you can use the paragraph designer to modify the tags used in the template. After that, you'll see changes when you open files or create new topics.

Customizing structure models and structured formatting

Along with built-in models like DITA and S1000D, FrameMaker provides the Structured Application Designer to help you set up the rules needed to use other custom XML or SGML content models.

Running FrameMaker as Administrator (recommended)

When modifying files in your application installation directories you may find you need additional write permissions to save files. Right-click on your FrameMaker application icon to choose Run as Administrator. This will allow you to save files that are normally protected during this FrameMaker session.

Modifying DITA templates

As DITA is a very popular content model, it makes sense to show you how to get to and modify the DITA templates. In the Structured Applications Definitions Document you can find the following default definitions for a DITA 1.3 topic:

The template file is stored inside the FrameMaker installation directory (represented by the $STRUCTDIR variable in this image) and we can open and modify this file to make branding or other format changes to the default template file.

If you decide to modify this file, I recommend making a backup copy and labeling it something like topic.template.backup.fm so that you don’t have to alter the current path or filename in this definition.

A previous post I wrote for Adobe contains some video for FrameMaker 11 that might help you visualize the process:

Changing other DITA options

There are some other minor tweaks you can make to your DITA environment using the EDD and using your DITA initialization files. They include altering the strawman structure you see when starting a new file, and changing the appearance and behavior of helper text designed to guide new users through new file creation.
