Zendesk Theme Delta
Delta is a documentation-style Zendesk theme inspired by API docs and technical knowledge bases. It features a persistent left sidebar for navigation and automatic article loading as you scroll—perfect for teams managing tutorials, developer guides, or detailed product documentation.
About the theme
Delta reimagines the help center layout for documentation-heavy use cases. Inspired by developer documentation sites, it places navigation in a persistent left sidebar while content occupies the main area, a format familiar to anyone who's used API docs or technical wikis.
The sidebar shows categories, sections, and articles in a tree structure, staying visible as users scroll through content. This makes it easy to understand the overall documentation structure and jump between related topics without losing context.
A unique feature: when you reach the end of an article, the next article loads automatically. This creates a seamless reading experience for tutorials and guides meant to be consumed in sequence, reducing clicks and keeping users engaged with your content.

How we customized Delta for customers
Frequently Asked Questions
What is documentation-style layout?
Documentation-style layout places navigation in a fixed left sidebar with content on the right—similar to sites like Stripe Docs, ReadMe, or GitBook. It's optimized for reference material that users browse and search frequently.
How does the automatic article loading work?
When you scroll to the bottom of an article, the next article in the section automatically loads below. This creates a continuous reading experience without clicking—ideal for tutorials where users work through content in order.
Is Delta suitable for non-technical content?
Yes. While Delta's design is inspired by developer docs, the sidebar navigation works well for any well-structured content. It's particularly effective when you have many articles organized into clear categories.
Can I customize the sidebar?
Yes. The sidebar appearance, including colors and behavior, can be customized in the theme settings. The navigation structure follows your Zendesk Guide category and section organization.

Do you offer a discount for startups?

Are themes ADA Compliant?
The most adapted themes for accessibility are Flatrock, Mink, Braden, Lotus One, Conway, and Selway. They are not fully ADA Compliant but have the following features:
- Keyboard navigation: themes are fully navigable by keyboard without the need for mouse interaction.

Skip links:
themes have skip links that allow users to bypass navigation and skip directly to content or

themes have micro animations but detect if the user has requested that the system minimize the amount of
non-essential motion it uses.
We are constantly improving the accessibility features for our themes.
