For a simple, swipeable row of cards, start with a horizontally scrolling container and CSS scroll snap. Use a small client-side React component when you need custom controls or state, and choose a library such as Embla when drag behavior, snap navigation, or grouped slides justify the extra dependency. Here are three practical approaches for a Next.js App Router project, with trade-offs and accessibility guidance for each.
Where the carousel belongs in a Next.js app
In the App Router, a route page is a default-exported React component in a page file under app. Keep content that needs no browser interaction in the page, and isolate stateful carousel behavior in a Client Component. This split is an implementation pattern, not a carousel-specific rule in the Next.js documentation. See the Next.js App Router documentation.
For example, a route might render a component from app/products/page.tsx, while an interactive carousel lives in app/components/ProductCarousel.tsx. Add 'use client' at the top of that component when it uses React state or browser interaction.
Choose an approach by the interaction you need
| Need | Start with | What you take on |
|---|---|---|
| A row users can swipe or scroll | Native overflow and CSS scroll snap | Browser scrolling and snap positions; little carousel-specific JavaScript. |
| A deliberately small, tailored interaction | Custom React component | You control markup and state, and own navigation, edge cases, and accessibility behavior. |
| Drag behavior, controlled snap navigation, grouped slides, or a richer gallery | Embla or another evaluated library | A dependency and its integration/version maintenance; accessibility remains your responsibility. |
This is a capabilities-based choice, not a speed or bundle-size ranking. Measure your own application if those factors determine the decision.

Method 1: Build a custom React carousel
A custom component is appropriate when the interaction is intentionally limited—for example, one visible product image at a time with previous and next buttons. Keep the slide content in data and let React render the selected item. This example does not loop: the buttons are disabled at the first and last items.
1. Add the client component
Create app/components/CustomCarousel.tsx:
'use client';
import { useState } from 'react';
type Slide = {
title: string;
description: string;
};
const slides: Slide[] = [
{ title: 'First item', description: 'Description for the first item.' },
{ title: 'Second item', description: 'Description for the second item.' },
{ title: 'Third item', description: 'Description for the third item.' },
];
export default function CustomCarousel() {
const [selected, setSelected] = useState(0);
function previous() {
setSelected((current) => Math.max(0, current - 1));
}
function next() {
setSelected((current) => Math.min(slides.length - 1, current + 1));
}
const slide = slides[selected];
return (
<section aria-label="Featured items" aria-roledescription="carousel">
<div aria-live="polite" aria-atomic="true">
<article aria-roledescription="slide" aria-label={`${selected + 1} of ${slides.length}`}>
<h2>{slide.title}</h2>
<p>{slide.description}</p>
</article>
</div>
<div>
<button type="button" onClick={previous} disabled={selected === 0}>
Previous
</button>
<button type="button" onClick={next} disabled={selected === slides.length - 1}>
Next
</button>
</div>
</section>
);
}The live region can announce the changed slide to assistive technology; verify the experience with the screen readers and browsers your users rely on. If the carousel contains essential information, do not make it available only by advancing through slides.
2. Render it from the route
In app/page.tsx, import and render the component:
import CustomCarousel from './components/CustomCarousel';
export default function Page() {
return (
<main>
<h1>Featured items</h1>
<CustomCarousel />
</main>
);
}The page itself can remain a Server Component; only the component that uses state needs the client boundary. This small example leaves styling, focus policy, and any richer keyboard interaction to the application. Native buttons provide keyboard-operable controls, but test the complete interaction rather than assuming the markup alone makes every carousel accessible.
Method 2: Use native scrolling and CSS scroll snap
For a row of cards that people can swipe on touch devices or scroll with a trackpad, native overflow is often the simplest starting point. The browser handles scrolling; CSS defines where scrolling should settle.

const items = [
{ title: 'First item', text: 'Details for the first item.' },
{ title: 'Second item', text: 'Details for the second item.' },
{ title: 'Third item', text: 'Details for the third item.' },
];
export default function Page() {
return (
<main>
<h1>Browse items</h1>
<div className="carousel" aria-label="Featured items">
{items.map((item) => (
<article className="carousel__slide" key={item.title}>
<h2>{item.title}</h2>
<p>{item.text}</p>
</article>
))}
</div>
</main>
);
}If the container is not a landmark or otherwise named by its surrounding structure, use an appropriate semantic wrapper and provide a clear accessible name. Avoid adding carousel semantics to a scrolling row unless it behaves like a carousel and the label helps users understand it.
2. Add scrolling and snap styles
Put this in a global stylesheet or the component’s CSS module, adapting the selectors to your setup:
.carousel {
display: grid;
grid-auto-columns: minmax(16rem, 80%);
grid-auto-flow: column;
gap: 1rem;
overflow-x: auto;
overscroll-behavior-inline: contain;
padding: 0 1rem 1rem;
scroll-snap-type: inline proximity;
}
.carousel__slide {
min-width: 0;
scroll-snap-align: start;
}scroll-snap-type belongs on the scrolling container, and scroll-snap-align on the items. The example uses proximity, which allows the browser to settle near snap positions without making every stop mandatory. Adjust the card width and spacing to fit the design and test on narrow screens.

Know which CSS carousel features you are using
The overflow-plus-scroll-snap pattern is distinct from newer CSS carousel UI features such as generated scroll buttons and markers described in MDN’s CSS carousel guide. Check current support for your target browsers before relying on those newer features; ordinary overflow and scroll snap do not require those controls.

Method 3: Use the Embla React library
A library can be useful when you need controlled snap navigation, drag interactions, or grouped slides rather than a basic scrolling row. Embla’s React integration uses a viewport ref around a container and slide elements, and its documentation recommends placing navigation controls outside the viewport to avoid drag conflicts. Its React wrapper handles cleanup when the component unmounts.
The available Embla React page identifies itself as v9.0.0-rc03 and directs users seeking the latest stable release to the v8 documentation. APIs can differ across versions: choose the version you install, then follow that version’s docs rather than mixing examples. See Embla’s React documentation and its v8 documentation.

Pick the symptom - the matching free tool is one click away.
1. Install the React package
For an npm project, install the React package:
npm install embla-carousel-reactConfirm the installed package version and use matching documentation. The following example illustrates the documented React structure and navigation API; check it against the version selected for your project before using it.
2. Create the carousel component
Create app/components/EmblaCarousel.tsx:
'use client';
import useEmblaCarousel from 'embla-carousel-react';
const slides = ['First item', 'Second item', 'Third item'];
export default function EmblaCarousel() {
const [emblaRef, emblaApi] = useEmblaCarousel({ align: 'start' });
return (
<section aria-label="Featured items" aria-roledescription="carousel">
<div className="embla__viewport" ref={emblaRef}>
<div className="embla__container">
{slides.map((slide, index) => (
<article
className="embla__slide"
aria-roledescription="slide"
aria-label={`${index + 1} of ${slides.length}`}
key={slide}
>
<h2>{slide}</h2>
</article>
))}
</div>
</div>
<div className="embla__controls">
<button type="button" onClick={() => emblaApi?.scrollPrev()}>
Previous
</button>
<button type="button" onClick={() => emblaApi?.scrollNext()}>
Next
</button>
</div>
</section>
);
}Keep controls outside the viewport so they do not compete with pointer dragging. Embla exposes previous/next snap navigation and the selected snap, and documents options for drag behavior and how many slides advance per action; consult the matching version’s API docs before configuring them. See Embla’s API documentation.
3. Add the layout styles
.embla__viewport {
overflow: hidden;
}
.embla__container {
display: flex;
touch-action: pan-y pinch-zoom;
margin-left: -1rem;
}
.embla__slide {
flex: 0 0 80%;
min-width: 0;
padding-left: 1rem;
}Render <EmblaCarousel /> from a page as in the custom-component example. The library supplies carousel mechanics, not a complete accessibility policy: label the experience, use native controls, make focus behavior understandable, and ensure changes are communicated when content is hidden or replaced.

Make the carousel usable with a keyboard and assistive technology
W3C’s Web Accessibility Initiative says, “All functionality, including navigating between carousel items, must be operable by keyboard.” See the W3C WAI Carousels Tutorial for guidance on keyboard operation, pause controls, communicating changes, and focus management.

Or skip the browser setup
If you also need screenshots of your carousel in a page, you can call ScreenshotNeo’s screenshot API instead of setting up a browser capture workflow. One GET request returns an image or PDF. See the ScreenshotNeo API documentation for options and response details.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpScreenshotNeo accepts cookie/consent banners and removes 60+ known consent platforms, newsletter popups, and chat widgets before capture; each cleanup step can be turned off. Bot checks/CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing, and responses report the page verdict and billing status in headers. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients. The Free plan includes 1,000 screenshots a month without a card; paid plans start at $5 for 3,000 shots. See ScreenshotNeo for details and sign up free for 1,000 screenshots a month, with no card required.
Troubleshoot common problems
The client component complains about hooks or browser APIs
React state and browser interaction must run in a Client Component. Put 'use client' at the top of the component file using hooks or browser APIs, rather than converting the entire route to client rendering unnecessarily.
The CSS row does not scroll horizontally
Check that the items form a single row, the container has overflow-x: auto, and the combined item width exceeds the available width. Confirm that the snapping rule is on the scrolling element and each item has scroll-snap-align.
Snap behavior makes some content hard to reach
Mandatory snapping can trap scrolling within oversized slide content. Try proximity, adjust the item sizing, and test with content that is taller or wider than the viewport.

Embla controls do nothing or drag feels wrong
Ensure the controls call methods on the initialized API and are outside the draggable viewport. Verify that your code matches the installed Embla version; the cited React docs are for a release candidate and stable users are directed to v8 docs.
Screen readers do not identify the carousel change
A visual slide change is not necessarily communicated to assistive technology. Provide meaningful labels and structure, then test announcements and focus with assistive technology. Avoid adding a live region indiscriminately; frequent or poorly scoped announcements can make navigation harder to follow.
Frequently asked questions
Does a carousel have to auto-play?
No. A user-controlled scroller or previous/next interaction is a carousel without automatic movement. If you do add auto-advance, users need a way to pause it.
Free tools Windows power users keep installed
One-click scans. No signup required.
Which method should I use for a simple card row?
Start with native overflow and CSS scroll snap when users mainly need to swipe or scroll through a row. It uses browser scrolling rather than a dedicated carousel engine.
Does Embla make a carousel accessible automatically?
No. It provides carousel mechanics, but the application still needs accessible naming, keyboard-operable controls, understandable focus behavior, and communication of changes.
