Provide accessible names for all interactive elements
rule · aria-labels
Every interactive element on a page must communicate its purpose to assistive technologies. WAI-ARIA 1.2 (opens in a new tab) treats accessible naming as foundational for buttons, links, and widgets, which is why this rule often overlaps with ARIA command names.
Code Example
HTML
<!-- ✅ Correct: Descriptive label for icon button -->
<button aria-label="Download PDF report">
<i class="icon-download"></i>
</button>
<!-- ✅ Correct: Descriptive link text -->
<a href="/pricing">View our subscription plans</a>
<!-- ❌ Incorrect: Non-descriptive label (Too generic) -->
<a href="/article/123">Read more</a>
<!-- ❌ Incorrect: No label (Icon-only without description) -->
<button>
<span class="glyph-print"></span>
</button>Why It Matters
- Efficiency: Helps users quickly scan and find the right control when using a screen reader's "elements list."
- Searchability: Clear labels are vital for users who navigate via voice control, as they need to speak the name of the control to activate it.
- Clarity: Removes ambiguity about what will happen when a control is activated, reducing user anxiety and errors.
- Consistency: Ensures that the experience for screen reader users matches the visual intent of the design.
Exceptions
- Prefer native HTML semantics over ARIA when both are possible; some apparent ARIA failures disappear when the underlying element is corrected.
- A missing ARIA attribute is not automatically the strongest finding if the control is already semantically broken, unnamed, or keyboard-inaccessible.
- Do not add ARIA only to satisfy the rule if the feature should instead be implemented with a native element or a simpler interaction pattern.
Standards
- Align the implementation with WAI-ARIA 1.2 and verify the rendered experience, not only the source code.
- Align the implementation with MDN: ARIA and verify the rendered experience, not only the source code.
Verification
Automated Checks
- Inspect the browser accessibility tree or accessibility pane for the relevant element, role, or accessible name.
- Run an automated accessibility checker such as axe or Lighthouse where applicable.
Manual Checks
- Test the affected UI with keyboard-only navigation and confirm the rule holds in the rendered experience.
- Re-test one representative user flow with a screen reader if this rule affects a key interaction.
