A Practical WCAG 2.1 Checklist for SaaS Dashboards

Roughly one in six people worldwide lives with a disability that affects how they use the web. For SaaS products, accessibility failures mean lost customers, support tickets, and legal risk. WCAG 2.1 Level AA is the standard most teams target — and it is entirely testable with the right tools.

Color contrast and visual design

Text must meet minimum contrast ratios against its background: 4.5:1 for normal text, 3:1 for large text (18px+ or 14px bold). This includes muted labels, placeholder text, and disabled states — not just body copy.

Never rely on color alone to convey state (use icons or labels for errors).
Test both light and dark themes — contrast often fails when switching modes.
Ensure focus indicators are visible with at least 3:1 contrast against adjacent colors.

Keyboard and focus management

Every interactive element must be reachable and operable with a keyboard alone. Tab order should follow visual reading order. Modals must trap focus and return it on close.

No keyboard traps — users must always be able to Tab out of any component.
Skip links for main content on pages with heavy navigation.
Visible focus rings on buttons, links, and form fields (never outline: none without a replacement).
Dropdowns and menus must support Arrow keys and Escape to close.

Forms, labels, and errors

Forms are where accessibility audits find the most violations. Every input needs a programmatic label. Error messages must be announced to screen readers and associated with the field that failed.

Use <label for="..."> or aria-label — placeholder text is not a label.
Group related fields with fieldset and legend where appropriate.
Surface validation errors in text, not only with red borders.

Automated testing with axe-core

LoopNode injects axe-core into a real browser session during each accessibility audit. It checks WCAG 2 A/AA rules and best practices, then groups violations by severity with selectors so your team knows exactly which elements to fix.
