Frequently Asked Questions
What is screen reader-only (sr-only) text?
Screen reader-only text is content visually hidden but accessible to assistive technologies like screen readers. It uses CSS techniques (position: absolute, clip, 1px dimensions) to hide content from sighted users while keeping it in the accessibility tree. Common examples include "Skip to content" links and form label clarifications.
Why do developers use sr-only content?
Developers add sr-only text to provide context that's obvious visually but missing for screen reader users. For instance, icon buttons need hidden labels, data tables may need hidden headers, and page sections often have hidden navigation landmarks. It bridges the gap between visual design and accessible experience.
What's the difference between aria-label and sr-only?
aria-label is an HTML attribute that provides an accessible name directly on an element, while sr-only uses CSS-hidden DOM text. aria-label doesn't appear in the DOM as visible text; sr-only text exists in the DOM but is visually hidden. Both serve screen readers but have different use cases and browser/translation tool behaviors.
How does this visualizer help with accessibility testing?
This tool reveals invisible accessibility content by parsing your HTML and highlighting hidden elements in a live preview. It detects sr-only classes, ARIA attributes, alt text, roles, and aria-hidden elements — giving you a complete map of what screen reader users actually encounter. Essential for accessibility audits and debugging.
What are common sr-only CSS patterns detected?
We detect Bootstrap's .visually-hidden / .sr-only, Tailwind's .sr-only, and custom classes matching patterns like screen-reader-text, assistive-text, and visuallyhidden. We also flag inline styles using clip, clip-path, or position:absolute with tiny dimensions (1px × 1px).
Can I test a live website URL with this tool?
Browser CORS policies may prevent direct URL fetching. For best results, use browser DevTools to copy the page's HTML (Right-click → View Page Source → Copy), then paste it here. This ensures you get the complete DOM including all sr-only and ARIA content.
