Sliders, Motion, and Video Fallbacks

Step 1: Configure the Slider Source
Select the Slider element and choose saved slides or approved dynamic content. Set a deliberate order, limit, image fit, and responsive height. Keep keyboard, swipe, arrows, dots, and a pause control available whenever the slider advances or changes content automatically.

Step 2: Use Motion with Restraint
Choose the transition, duration, delay, easing, and optional image motion for a clear purpose. Avoid rapid autoplay or movement that hides information before it can be read. Reduced-motion visitors should receive a stable version without losing the slide content or controls.

Step 3: Build the Video Fallback Chain
For video, set HLS as the primary stream when available, then provide a compatible MP4, WebM, or media-library fallback. Add a poster and a separate failure image. Configure controls, preload, fit, title, mute, loop, and autoplay according to the video's actual role.

Step 4: Verify Playback and Layout
Test desktop, tablet, and mobile with normal and reduced motion. Check HLS support, file fallback, blocked autoplay, poster loading, failure image, captions where speech matters, keyboard controls, focal framing, and page containment. A working administrator preview is not the final playback test.
