accessibility:
  keyboard_support:
  - Tab to navigate to tab list
  - Arrow keys (Up/Down) to navigate between tabs
  - Enter or Space to activate a tab
  - Home/End to jump to first/last tab
  screen_reader:
  - Tab list role announced
  - Active tab state announced
  - Tab panel content associated and announced
  - Disabled tab state announced
  aria_attributes:
  - role='tablist' on navigation container
  - role='tab' on tab links
  - role='tabpanel' on content panels
  - aria-selected on active tab (true/false)
  - aria-controls linking tab to panel
  - aria-labelledby linking panel to tab
  - aria-disabled on disabled tabs
  - tabindex='0' on active tab, '-1' on others
usage_guidelines:
  when_to_use:
  - When you have multiple content sections to organize
  - For settings pages or configuration interfaces
  - When horizontal space is limited but vertical space is available
  - For side navigation patterns
  - When content sections are related but distinct
  when_not_to_use:
  - When horizontal tabs work better for the layout
  - For primary navigation (use global navigation)
  - When only 2-3 sections exist (consider accordion)
  - In very narrow viewports
  best_practices:
  - Keep tab labels short and descriptive
  - Provide clear visual indication of active tab
  - Ensure adequate spacing between tabs
  - Support keyboard navigation fully
  - Maintain tab state during navigation
  - Use icons to enhance tab meaning when helpful
  common_mistakes:
  - Not implementing proper ARIA tab patterns
  - Missing keyboard navigation
  - Inadequate visual feedback for active state
  - Too many tabs making navigation difficult
  - Not maintaining tab state
