Semantic headings, a skip link, visible focus, native controls and labeled results support keyboard navigation. Color alone never communicates route status.
Without scripts
Complete compatibility tables, articles, citations and downloads remain available without JavaScript. The local helper supplements those answers.
Small screens and print
Wide tables scroll inside labeled, keyboard-focusable regions. The page itself reflows. History uses expandable chapter navigation; print styling keeps references readable.
Limits
These features are not accessibility certification or proof of testing by disabled readers. External sites have their own behavior. Individual assistive-device recommendations are outside our documentary scope.
