Title: Accessibility in Design Systems: Building from Scratch
Introduction
Web accessibility is no longer a “nice-to-have” feature—it’s a business-critical necessity. Whether you're designing a website, developing a web app, or building out a design system, accessibility should be foundational from the very beginning. Ignoring it not only alienates millions of users with disabilities but also increases legal risk, impacts SEO, and damages your brand's reputation.
As global web accessibility regulations like WCAG (Web Content Accessibility Guidelines), EN 301 549, and the European Accessibility Act (EAA) become stricter, organizations must proactively prioritize inclusive design. But where do you start if you're building a design system from scratch?
This blog explores how to embed accessibility into the DNA of your design system from the ground up. We’ll also look at how solutions like allyWay can support, streamline, and scale your accessibility efforts without promising legal guarantees.
Why Accessibility Should Be Built Into Design Systems
Design systems are more than style guides—they’re the blueprint for your entire digital ecosystem. Every button, form, icon, and interaction flows from the design system. That’s why failing to integrate accessibility early creates technical debt, inconsistencies, and barriers for users.
Benefits of Accessible Design Systems
✓ Consistency: Accessibility baked into components ensures a consistent user experience across all products.
✓ Scalability: Teams can reuse accessible components without reinventing the wheel.
✓ Efficiency: Reduces future retrofitting efforts that can be time-consuming and expensive.
✓ User-Centered: Builds better experiences for everyone, including users with visual, auditory, mobility, or cognitive impairments.
✓ Future-Proofing: Aligns with evolving standards like WCAG 2.2 and upcoming WCAG 3.0.
Foundational Accessibility Standards to Know
Before diving into implementation strategies, it’s essential to understand the key accessibility standards and regulations that influence design decisions.
Web Content Accessibility Guidelines (WCAG)
WCAG, developed by the W3C, lays out international best practices for web accessibility. WCAG 2.1—and soon WCAG 2.2—offers guidelines under four key principles:
- Perceivable: Information must be presented in a way users can perceive.
- Operable: Interface components should be usable with a keyboard or assistive tech.
- Understandable: Content and navigation should be clear and predictable.
- Robust: Content should be able to be interpreted reliably by assistive technologies.
EN 301 549 and the European Accessibility Act
EN 301 549 is the European standard that applies WCAG principles to public sector and now, increasingly, private sector services under the EAA. If your audience includes European users, aligning with EN 301 549 is critical.
ADA and Section 508 (U.S.)
While the Americans with Disabilities Act (ADA) doesn’t specify technical standards, U.S. courts recognize WCAG as the de facto accessibility benchmark. Section 508 of the Rehabilitation Act also requires federal websites to meet accessibility standards.
Key Steps to Embed Accessibility in Your Design System
Step 1: Define Accessibility Guidelines Upfront
Start with a clear, accessible design strategy. Every design system should begin by outlining what accessibility means for your organization.
Include:
- Your target compliance level (e.g., WCAG 2.1 AA)
- Component-level accessibility requirements
- Semantic HTML usage standards
- Color contrast rules (WCAG 2.1 requires 4.5:1 for text)
- Keyboard navigation specs
- Use of ARIA (Accessible Rich Internet Applications) roles and attributes
Step 2: Design with Inclusion in Mind
In the design phase, anticipate how people with different abilities will interact with your interfaces.
Best practices:
- Use high-contrast, readable typography
- Avoid relying on color alone to convey information
- Design flexible layouts that can scale on various devices
- Ensure visible focus states and logical navigation order
Tip: Tools like allyWay support visual testing with its accessibility overlay, enabling designers to preview how elements appear through different lenses (e.g., color blindness, low vision).
Step 3: Build Accessible Components
Accessibility needs to be enforced at the component level. From buttons to modals, every UI element should be fully accessible.
| Component | Accessibility Considerations | |
|---|---|---|
| Buttons | Must have clear labels, focus states, and roles | |
| Forms | Inputs need labels, error messaging, and ARIA support | |
| Modals | Should trap focus, allow ESC to close | |
| Navigation Menus | Should be keyboard-navigable | |
| Tables | Headers | , captions, and logical row/column order |
Make accessibility part of your component lifecycle—design, development, review, and testing.
Step 4: Document Everything for Developers and Designers
Documentation is central to the success of a design system. Accessibility guidelines should be written clearly so all contributors—designers, developers, QA—can follow them.
Consider including:
- Code snippets for accessible patterns
- ARIA usage examples (and when not to use ARIA)
- Color palettes with contrast ratios
- Keyboard interaction flows
Pro Tip: Treat documentation as a knowledge base. allyWay’s AI-powered platform can also help surface insights and progress through accessibility audits, helping maintain standards over time.
Step 5: Automate and Test Continuously
Building accessible components is just the beginning—it’s essential to test them.
Testing Methods:
-
Automated Testing: Useful for flagging common issues like missing labels, contrast errors, etc. allyWay provides AI-powered auditing that helps identify and categorize accessibility gaps efficiently.
-
Manual Testing: Needed to evaluate keyboard navigation, screen reader behavior, and overall user experience.
-
Assistive Technology Testing: Use popular screen readers like NVDA, JAWS, VoiceOver to ensure compatibility.
-
User Testing with People with Disabilities: The gold standard for accessibility validation.
Make accessibility testing part of your CI/CD pipeline so it's automatic and repeatable.

- Write accessible user stories (e.g., “As a blind user, I can navigate the modal via keyboard.”)
- Include accessibility acceptance criteria
- Perform accessibility checks during code review
- Schedule quarterly accessibility audits using allyWay’s platform
Scaling Accessibility Across Organizations
A design system with built-in accessibility benefits not just developers but the whole organization.
How companies can scale accessibility:
- Offer training for design and dev teams
- Assign accessibility champions in each department
- Use allyWay to monitor improvements and perform regular audits
- Foster a culture where accessible design is the default
Top Mistakes to Avoid
Even well-meaning teams can stumble if they’re unaware of common pitfalls.
Avoid:
- Hard-coding inaccessible components like non-semantic div buttons
- Relying solely on visual cues (e.g., red outlines for errors)
- Skipping keyboard testing
- Assuming automation catches everything
By using tools such as allyWay, many of these issues can be flagged early, helping teams begin remediation proactively.
