Design systems are no longer a nice-to-have. For enterprise organizations, they are essential infrastructure, a unifying foundation for creating consistent, on-brand, and scalable digital experiences across platforms, teams, and markets.
But here’s the paradox:
Most design systems don’t fail because of bad design. They fail in implementation.
They live in beautifully structured Figma files, supported by exhaustive documentation, only to be misinterpreted, diluted, or outright broken when translated into code. What starts as a crisp visual identity becomes inconsistent in production. Development slows. Frontend teams rely on overrides and workarounds. UX suffers.
Why?
Because the frontend architecture wasn’t designed to scale the design system, and without the right architectural foundation, design systems become expensive slide decks, not operational assets.
In this blog, we unpack how Axelerant tackled this challenge head-on: by building a frontend system for Drupal 11 that doesn’t just "support design", it operationalizes it. Through modular architecture, Tailwind-driven design tokens, and component-based theming, we helped an enterprise organization transform its design system into a high-velocity delivery engine.
This is how you scale design, not just as an idea, but as a practice.
Drupal’s legacy themes, like Bartik or Classy, were never designed with systematized design principles in mind. They come preloaded with default styles and structures, forcing teams to fight against the system instead of building with it.
As projects grow, this becomes a serious issue:
Design teams operate with a clear system. Developers operate with legacy overrides and conflicting codebases. The result? Inconsistency, delays, and expensive rework.
To address this, Axelerant implemented a custom frontend architecture for Drupal 11 built entirely around design-system principles. The foundation rested on three key decisions:
Stable9 is a minimalist Drupal-based theme that provides clean, unopinionated markup. Unlike legacy themes, it doesn’t inject default styles or assumptions, giving designers and developers full control of the visual layer from the start.
This decision allowed the frontend team to build the UI from a clean slate, reducing inherited complexity and aligning markup with design needs.
Tailwind’s utility-first philosophy perfectly complements design systems. Instead of writing custom CSS for every element, developers use atomic utility classes directly in templates. Tailwind’s configuration file (tailwind.config.js) was extended to mirror the design system’s color palette, typography scale, spacing system, and breakpoints.
This effectively turned the design system into a set of programmable tokens, enabling design intent to flow directly into code.
Each component, like a Hero section, CTA, or Feature Card, was stored in its own self-contained directory. These directories included:
component.html.twig – Templatecomponent.ts – TypeScript logiccomponent.css – Custom styles (used sparingly with Tailwind overrides)SDC provides several enterprise-grade benefits:
One of the most important outcomes of this architecture was how well it mapped to the design system’s structure and philosophy. This helped achieve the following:
Tailwind’s token system was configured to reflect the design system directly:
For example, adding a new spacing token meant updating the Tailwind config once, making it available across all components instantly, without writing custom CSS. Likewise, introducing a new color or breakpoint followed a centralized update flow, eliminating style drift.
This created a single source of truth across design and development, implemented in a way that was scalable, maintainable, and future-ready.
With this architectural system in place, every team moved faster, and with more clarity.
As enterprises continue to scale their digital presence, investing in robust design systems becomes not just beneficial but essential. This type of design system provides a blueprint for organizations looking to implement design systems that can grow with their needs while maintaining the quality and consistency users expect.
Because the team worked with reusable, pre-aligned components, the time required to design, build, and deploy new sections of the site was significantly reduced. Features didn’t need to be coded from scratch; they were composed from a modular system already aligned with the design language.
Multiple teams contributing to the platform could rely on the same set of tools, tokens, and structures. Whether working on different features or regions, the UI remained consistent, protecting brand equity and user experience at scale.
By enforcing consistency at the architectural level, the platform eliminated redundancies, reduced bugs, and avoided style conflicts. Technical debt was minimized, allowing for easier refactors and faster iterations in the long term.
Because the architecture aligned closely with the design system, there was less tension between teams. Designers saw their intent respected in code. Developers didn’t have to guess. QA had fewer edge cases to track. This streamlined delivery and boosted team satisfaction.
With tokenization and modularity built in, the platform was ready for future enhancements, from regional microsites to personalized user journeys, without needing to rework foundational frontend logic.
The organization’s investment in design strategy didn’t stop at a PDF or Figma board. It became a tangible, operational framework powering real experiences. This architecture turned design from a vision into a product.
Design systems are only as powerful as the systems that support them. Without the right frontend architecture, even the best design systems degrade over time, falling victim to misinterpretation, inconsistency, and technical debt.
By rethinking the frontend from the ground up, Axelerant helped ensure that design decisions weren’t just referenced, they were enforced, accelerated, and sustained.
This is what true design scalability looks like: not just consistency in the style guide, but consistency in production. Not just documentation, but delivery. Not just alignment, but acceleration.
Is your design system operational, or ornamental? Let’s build the architecture that helps you scale it.
