Build feature tours and product walkthroughs by stacking small sections, each one getting its own moment on the right without extra wiring.
Swap in real markup, an embed, or an image for every section so the sticky card always shows content that already lives on the page.
No animation library and no scroll-jacking: one passive scroll listener on the internal scroll container drives every transition.
The same breakpoint math ports cleanly to the Angular and React builds, so buyers see identical behavior no matter which license they hold.
