Accessible Shopify Themes in Practice: WCAG 2.2 Checklist, Common Failures, and Fixes You Can Ship Today

The fastest way to grow conversion and reduce risk is to make your storefront work for everyone. That includes shoppers using keyboards, screen readers, magnifiers, or simply their thumbs on bumpy buses. Shopify already signals the direction of travel, since the Shopify accessibility statement says it uses WCAG 2.2 as a guiding principle and tests key products like Checkout against WCAG 2.2 AA. On the legal front, the 2024 UsableNet report shows more than 4,000 digital ADA lawsuits, with ecommerce named in 77 percent of cases and 41 percent of federal suits hitting repeat defendants, and more than 1,000 businesses with an accessibility widget still received lawsuits. That pattern, outlined in the UsableNet 2024 Year End ADA Web Lawsuit Report, is a strong nudge to fix issues at the source.

WCAG 2.2 essentials for Shopify themes

WCAG 2.2 adds nine success criteria on top of 2.1 that map neatly to common storefront patterns. The W3C’s overview of what is new in WCAG 2.2 highlights practical changes you can implement now:

  • Focus not obscured AA: Ensure the focused element is not hidden by sticky headers, banners, or drawers, as described in SC 2.4.11.
  • Target size minimum AA: Make tap targets at least 24 by 24 CSS pixels or provide adequate spacing, per SC 2.5.8.
  • Dragging movements AA: Offer a single pointer alternative to drag operations, per SC 2.5.7.
  • Consistent help A and redundant entry A: Keep help in the same relative order and avoid retyping previously provided info, see SC 3.2.6 and SC 3.3.7.
  • Accessible authentication AA: Do not require cognitive puzzles or excessive recall to log in, per SC 3.3.8.

If you want the canonical details, the WCAG 2.2 technical specification provides the full criteria and definitions.

A practical WCAG 2.2 checklist for Shopify builders

Shopify documents a theme-focused playbook that aligns to WCAG, including keyboard patterns, form labels, and color contrast. The platform’s own guidance in Shopify’s Accessibility best practices for themes is an excellent companion to WCAG. Use this checklist when reviewing your theme:

  • Keyboard and focus: Every interactive control is keyboard reachable, focus styles are visible on desktop, and focus order follows DOM order. Avoid context changes on focus.
  • Focus visibility and obstruction: Add a clear focus indicator and prevent sticky UI from covering focused elements, which addresses WCAG 2.2’s focus-not-obscured requirement.
  • Pointer targets: Primary controls and links are large enough. Shopify recommends 44 by 44 pixels for primary touch targets, and WCAG 2.2 AA requires at least 24 by 24 pixels or spacing.
  • Drag alternatives: Price sliders, sort handles, and carousels support simple click or keyboard alternatives to dragging.
  • Forms: Every field has a visible or programmatic label, required fields use the required attribute, error messages are clear and referenced with aria-describedby, and autocomplete is used where applicable.
  • Dynamic changes: Announce price or availability changes with aria-live when variants update.
  • Contrast: Body text meets 4.5:1 minimum contrast and icon or control outlines meet 3:1, matching WCAG contrast rules and Shopify’s color guidance.
  • Help and repetition: Provide consistent help locations and avoid redundant entry during checkout or account flows.
  • Auth paths: Prefer password managers, magic links, or copy and paste friendly flows to avoid cognitive function tests.

Common failures ThemeProbe users spot and fixes you can ship today

You can explore accessible design patterns in the wild, then identify the theme behind them with ThemeProbe. When you see a polished store and wonder how they did it, ThemeProbe gives instant theme detection, no signup, with a lightweight UX and local-only search history. The tool is perfect for competitive research, which we cover in Shopify competitive benchmarking with theme detection. Here are the failures we see most often, with quick fixes:

  1. Focus outlines removed by CSS resets. If links and buttons have no visible focus state, keyboard users will get lost. According to WCAG 2.2’s Focus Appearance, the focus indicator needs sufficient size and contrast. Fix by restoring outlines or adding a 2 px outline or box shadow with a 3:1 contrast against surrounding UI. Shopify’s best practices page also stresses visible focus on desktop.

  2. Tiny tap targets in navigation and filter chips. Shoppers miss small radiobuttons or tags on mobile. WCAG 2.2 AA calls for 24 by 24 pixels minimum or spacing. In practice, raise tap areas with padding, add min-width and min-height, and separate controls with adequate gap. For critical actions like Add to cart, meet or exceed Shopify’s 44 by 44 guidance.

  3. Sticky headers and cookies banners that hide focus. This violates SC 2.4.11 Focus Not Obscured. Mitigate with offset scrolling and scroll-margin-top on anchors, move focus into the opened component, and ensure any sticky or fixed element does not cover the focused control. Test with keyboard, not just mouse.

  4. Sliders and drag-only interactions. Price or size sliders that require dragging fail SC 2.5.7 Dragging Movements. Provide plus or minus buttons, a text input, or click on a track to move the handle. Ensure keyboard arrows adjust values with reasonable increments.

  5. Memory-heavy login or CAPTCHA. For account pages, Accessible Authentication prohibits pure cognitive tests without alternatives. Offer one-time email links, allow paste for OTPs, and let password managers fill fields. If you must use a challenge, provide an accessible alternative.

  6. Low-contrast badges, sale pills, and disabled buttons. As WCAG contrast minimum requires 4.5:1 for normal text and 3:1 for large text, raise background lightness or darken text, and ensure non-text UI like input borders meet 3:1. Shopify’s guidance recommends checking contrast with reliable tools.

How to audit fast and benchmark smarter

Shopify recommends using automated and manual tools in its own docs. The platform lists Accessibility Insights, Lighthouse, and WAVE in the Shopify theme accessibility guide. Add these to your CI with Lighthouse CI to catch regressions, then do focused manual checks for keyboard traps, focus order, and dynamic announcements.

When benchmarking competitors, try this workflow:

  • Paste a store URL into ThemeProbe to identify their theme instantly, then note accessibility patterns you admire.
  • Build a lightweight swipe file of accessible patterns using ThemeProbe’s local-only search history. We explain the research approach in our blog, and we are open about acceptable use and affiliate disclosures in our Terms and Privacy Policy.

Finally, not every theme is equal and some stores run custom stacks, which means detection can vary. As Shopify’s own VPAT for Dawn explains, the default theme aims for WCAG 2.1 AA, with some partial support areas outlined in the Shopify Dawn theme VPAT. Treat WCAG as your north star and test your actual implementation.
