Each section is one screen. → / ← move between pages. Add data-title to name it in the dock.

Hidden at first. Each → reveals the next one; ← hides it again. Only after all steps, → turns the page.

Steps with the same number appear together on one press — great for a diagram plus its caption.

Automatically run your JavaScript (an animation, a sound, a counter) the moment the step appears. Use data-step-reverse for undo.

A hidden inner page. A card/button calls openSubslide('id'); the Back button closes it. It gets its own pen notes and its own steps.

A video or audio starts playing when it appears and is paused + muted automatically when you move away.

Elements glide, pop, or fade in when the slide opens. Add delay-100…700 to stagger them.

Write your own <script> function; the slider makes it work from buttons instantly.

Put files in the deck's images/ folder; the slider finds them automatically.

Wrap in an IIFE to isolate scope. Use Click-to-Play for sound, and auto-pause with MutationObserver on slide change.

Invisible on stage — sent to the synced second window, so only you see your teaching tips.
