Working with styles in documentation outputs can be one of the most time-consuming aspects of a technical writer's workflow. For ePublisher users, managing style properties across hundreds of different content elements has historically required careful attention to detail and significant time investment. With our latest update in ePublisher 2024.1, we've reimagined how style inheritance works to dramatically simplify this process and give you more control with less effort.

The Challenge with Previous Style Inheritance

The Style Designer has always been the central hub where ePublisher users manage styles imported from various source documents—whether DITA, FrameMaker, Microsoft Word, or Markdown++. While our previous inheritance system worked well for many users, it had some limitations that became particularly evident when working with complex documentation projects.

Previously, when a Style Property was set to its default value (usually 'Inherit from default Style'), ePublisher would still create value nodes in the Stationery file. This approach had an unintended consequence: it often blocked the inheritance chain on nested styles, requiring users to make the same changes multiple times across different style elements.

We encountered a vivid example of this challenge when a customer approached us with a massive Stationery overhaul. They were overwhelmed by hundreds of style customizations that seemingly all needed individual attention. After examining their setup, we discovered that many of these "customizations" were actually just inheriting default values—but because of how our system tracked inheritance, they appeared to be unique modifications requiring manual updates. Moreover, there were many instances where the a Style Property was set to 'Inherit from default Style' but no value was set, leading to confusion and a lack of certainty about which styles were actually inheriting from their parent styles. Notice in this image how the Color property is set to Inherit and the value is blank, which could lead us to believe the style is inheriting from it's parent, even if the value is not being reported:

We found many instances where there were blank value nodes in the Stationery file, which would ultimately break the inheritance chain, even though to the user it appeared that the styles were inheriting correctly.

Additionally, Style Options—which control behavioral elements like TOC inclusion or paragraph numbering—weren't inheritable at all. Each option had to be set individually on every style, creating significant redundancy when managing large documentation sets.

Introducing Smarter Style Inheritance

Our updated inheritance system in ePublisher 2024.1 takes a fundamentally different approach. Instead of creating explicit value nodes for properties that are effectively using default values, the system now assumes inheritance when no explicit customization exists. This seemingly simple change has profound implications for how you'll interact with styles.

Here's what's different:

  1. Cleaner Stationery Files: The system now removes value nodes in the Stationery that ePublisher deems to be default, rather than populating the Stationery with redundant style property nodes.

  2. True Inheritance Chain: When a property isn't explicitly defined, ePublisher will continue looking upward in the style hierarchy until it finds the correct value, ultimately ending with either the user's source document or a default value from ePublisher.

  3. Option Inheritance: Perhaps most significantly, Style Options can now be inherited—meaning you can set an option once at a higher level and have it cascade down to child styles.

  4. Visual Clarity: The Style Designer now more clearly indicates where a property originates from, reducing visual noise and making it easier to identify true customizations.

Practical Benefits: Real-World Examples

Let's look at how these changes improve your day-to-day workflow with three concrete examples:

Example 1: Global Style Changes via [Prototype]

The [Prototype] Style has gained newfound importance with this update. Any style applied to [Prototype] will now effectively cascade to all other styles that don't explicitly override that property. This makes global typography or color changes remarkably simple:

  1. Apply your desired font change to [Prototype]
  2. Watch as the change propagates to all styles that don't specifically override font settings
  3. Selectively override only where necessary

For projects that need to maintain consistent branding or conform to new style guidelines, this can reduce hours of work to mere minutes.

Example 2: Mass Application of Style Options

Previously, if you wanted to set page break priority for all heading styles, you would need to set this option individually for each heading style. Now, you can:

  1. Set the page break priority option on a parent style
  2. Have that option automatically apply to all child styles
  3. Only override exceptions where needed

This inheritance of options is especially valuable for setting search relevance, toggling output settings, or controlling exclusions across large groups of similar styles.

Example 3: Clearer Origin Identification

When working with complex style hierarchies, it could be challenging to determine exactly where a particular property value originated. The updated Style Designer provides clarity by explicitly indicating the source, as shown in this image of a property inheriting from the [Prototype] style:

This visual indicator makes troubleshooting and style management far more intuitive, particularly when onboarding new team members who aren't familiar with the project's style structure.

Backward Compatibility and Transition

We've designed this enhancement to be fully backward compatible. If you're using a Stationery file from a previous ePublisher version, it will continue to work as expected in version 2024.1 and beyond.

When you modify styles using the new system, you may notice visual changes in the Style Designer interface. In particular, you'll see less bolding of style names and properties since we're now only highlighting truly customized elements rather than inherited ones. This reduction in visual noise makes it easier to focus on what really matters—your actual customizations.

As you make changes to your styles, ePublisher will automatically prune stale inherited nodes from your Stationery. This "cleanup" happens seamlessly as you work, gradually optimizing your Stationery files without requiring any manual intervention.

Best Practices for the New Inheritance System

To get the most from the enhanced Style Designer, consider these best practices:

  1. Start at the Top: Begin by setting common properties at the highest appropriate level in your style hierarchy. The [Prototype] style is ideal for truly global settings.

  2. Use Parent Styles Strategically: Create parent styles for groups of related elements (like all headings or all notes) to leverage inheritance efficiently.

  3. Only Override When Necessary: Resist the temptation to explicitly set properties that could be inherited. By keeping your customizations minimal, you'll maintain more flexibility for future changes.

  4. Pay Attention to Visual Cues: The reduced bolding in the Style Designer interface isn't just a visual change—it's valuable information about where your customizations actually exist.

  5. Clean Up Old Stationery: While not required, allowing ePublisher to prune stale inherited nodes by reviewing and modifying styles can improve performance and make future updates smoother.

Conclusion

The enhanced inheritance system in ePublisher 2024.1's Style Designer represents an important step forward in streamlining documentation workflows. By implementing a more logical and intuitive approach to style inheritance, we've reduced the complexity of style management while giving you more control over your output appearance.

These improvements were born directly from customer feedback and real-world usage scenarios. We identified a common pain point—the overwhelming complexity of managing styles across large projects—and reimagined the inheritance system to address it directly.

The result is a more efficient way to work with styles that saves time, reduces redundancy, and gives you clearer insight into how your style customizations actually function. Whether you're working with a simple documentation set or managing enterprise-level content across multiple outputs, the enhanced Style Designer makes your job easier.
