Synced Compare Carousel
Two side-by-side scroll-snap tracks that move in lockstep, so dragging either one snaps the other to match. A mobile-friendly comparison carousel rather than a single drag-reveal slider.
$ velocityx add synced-compare-carousel
Built for react.
Needs react already installed
as a peer dependency.
An Astro-only project needs @astrojs/react wired up first — this won't run on its own in plain Astro.

| className | string | No | '' |
Using it
The smallest call that compiles — required props only. The import is
written for your own file at src/components/Example.jsx;
adjust the relative import if yours sits elsewhere.
Everything optional is in the table above, with its default.
import SyncedCompareCarousel from './velocity/synced-compare-carousel/SyncedCompareCarousel';
export default function Example() {
return (
<SyncedCompareCarousel />
);
}Built from Synced Compare Carousel's own prop signature and the path the CLI installs it to, so it can't drift from either.
Accessibility
- ARIA roles
- region, tab, tablist
- ARIA attributes
- aria-label, aria-roledescription, aria-selected
- Keyboard
- Handles key events directly
- Focus
- Moves or traps focus deliberately
Read from the source, not asserted — anything not listed simply isn't in this component's markup.
Behaviour
- Ships client JS
- Yes — this one needs to hydrate
- React hooks
- useCallback, useEffect, useRef, useState
Theming
This component paints from 3 steps of
your theme scale — no hardcoded colours, and no font-family of
its own, so your type cascade wins. Override the variables and it follows.
primary-500primary-600primary-700Get the Velocity preset and CSS theme from the public source guide. The CLI theme command is not available on npm yet.
File this creates
The CLI writes this path into your project — nothing
else moves. Paths are under your source root, which defaults to
src/; pass
--dest if yours is elsewhere.

How do I install Synced Compare Carousel?
Run velocityx add synced-compare-carousel . The CLI writes the source straight into your project — it is not a runtime package dependency.
Do I need a licence for Synced Compare Carousel?
Yes. It is part of the lifetime library — buy access at https://aidxn.com/shop/velocity-x-component-library/, authenticate once, and install it. Your lifetime licence includes future component updates.
Can I edit Synced Compare Carousel after installing it?
Yes — the files are yours once written. The CLI compares its lockfile hash before upgrades and refuses to overwrite code you changed.
Does Synced Compare Carousel ship JavaScript to my users?
Yes. It runs in the browser (useCallback, useEffect, useRef, useState), so it needs to hydrate — in Astro, give it a client:* directive.
Will Synced Compare Carousel match my brand colours?
Yes. It paints entirely from your theme scale — 3 steps of primary-* / accent-* — with no hardcoded hex values and no font-family of its own. Override the theme CSS variables and it follows your design system instead of ours.
Is Synced Compare Carousel accessible?
It ships ARIA roles (region, tab, tablist), 3 ARIA attributes, its own keyboard handling, deliberate focus management. That is read directly from the source rather than claimed — you should still test it in the context you drop it into.
Does Synced Compare Carousel pull in any dependencies?
No external ones. Every component in the library is built with react/react-dom or plain Astro only — no GSAP, Radix, Swiper or Headless UI — which is what makes dropping it into an existing project safe.
