History and current state of making HTML5 Canvas accessible with concrete features and a live demo: browsers now expose hit regions and drawFocusIfNeeded so canvas pixels map to DOM fallback elements, with transparent regions tied to paragraph controls and aria-live status updates; a prototype game Whack a Creeper uses nine grid cells, 10 creepers total, score +/-10, and relies on Firefox Nightly (enable canvas.focusrings.enabled and canvas.hitregions.enabled) to show focus rings and screen‑reader interaction.
