  description

  Vesper Inspect is a lightweight accessibility inspection tool for web developers, designers, and content teams. Enable it on any page and hover over elements to instantly surface their accessibility attributes in a clean overlay - no DevTools required.
  WHAT IT SHOWS
  
  ARIA label, role, and computed accessible name (resolved from aria-labelledby, text content, alt text, and title - in priority order)
  Alt text on images, with clear error/warning/pass status
  Explicit and implicit ARIA roles
  Title attribute
  Tab order and keyboard reachability - including ancestor context (e.g. an image inside a link)
  Font information for text elements (size, weight, family, and large-text classification)
  Image file size (reads from browser performance timeline, no extra network requests)
  Phone number links (tel:) without descriptive labels - flagged so screen reader users can distinguish multiple numbers
  Email links (mailto:) without descriptive labels - same reason
  
  STATUS AT A GLANCE
  The tooltip header changes color based on what it finds:
  🟢 Green - element looks clean
  🟡 Amber - potential issue worth reviewing
  🔴 Red - confirmed accessibility problem
  TOOLTIP MODES
  
  Mouse mode - tooltip follows your cursor as you hover
  Tab mode - tooltip stays fixed top-right and updates as you tab through the page

  WHAT IT SHOWS
  
  ARIA label, role, and computed accessible name (resolved from aria-labelledby, text content, alt text, and title — in priority order)

  ARIA state attributes — aria-expanded, aria-pressed, aria-checked, aria-selected
  Link destination — shows the href value on any anchor element
  Form field details — required, disabled, read-only, and autocomplete (flags missing autocomplete on email, tel, and password fields per WCAG 1.3.5)
  Tab order and keyboard reachability — including ancestor context (e.g. an image inside a link)
  Font information for text elements (size, weight, family, and large-text classification)
  Image file size — reads from the browser performance timeline; flags images over 1 MB
  Phone number links (tel:) without descriptive labels
  Email links (mailto:) without descriptive labels
  
  STATUS AT A GLANCE
  The tooltip header changes color based on what it finds:
  
  Green — element looks clean
  Amber — potential issue worth reviewing
  Red — confirmed accessibility problem
  
  TOGGLE
  Click the toolbar icon to enable or disable the inspector. The icon badge shows ON when active. You can also use the keyboard shortcut Option+Shift+I on Mac (reassignable from chrome://extensions/shortcuts).
