Accessibility
More than one way to learn
Reading choices
Course and lesson pages offer light and dark reading modes. Browser zoom can enlarge text. The floating reader offers read aloud, pause, resume, stop, speed choices, and available browser voices. Written content remains available when a video or voice cannot play.
Navigation and motion
We use labeled buttons, visible keyboard focus, headings, and semantic page sections. Social icon labels appear on hover or keyboard focus. Motion is reduced when the browser’s reduced-motion preference is enabled.
Video access
Video captions, transcripts, playback controls, and availability are managed by the original publisher. Optional viewing supplements the written explanation and practice rather than replacing them.
Ongoing improvement
We are improving keyboard use, contrast, mobile layout, and the clarity of instructions. This statement does not claim a completed accessibility certification or a formal conformance audit.
