IFullscreen

Present an element or the page fullscreen.

• Wraps: Fullscreen API
• MDN: Fullscreen API
• Home: Rask.Wasm.Browser (WASM only)
• Shape: one-shot
• Availability: Web/Server 🟡 · PWA/WASM ✅

Needs transient activation, so the imperative IFullscreen service is WASM-only. On the Server host, use the declarative FullscreenTrigger component — its click requests fullscreen inside the gesture (the activation survives, unlike a round-tripped service call).

🟡 On the Server host, reachable declaratively via FullscreenTrigger (a click-gesture component), not as an injected service.
