Image compare
A React component in Beamline's Content & display category.
Two images in one frame with a divider: drag anywhere, or arrow keys on the handle; horizontal or vertical, with captions.
Use it for
- Before and after: edits, grades, renders.
Not for
- Comparing numbers (charts or diff-table).
Anatomy
- frame (media: the look's surface edge only, drawn over the pictures)
- after layer
- before layer (clipped)
- captions (inverse tooltip pair, read the same over any picture)
- divider line
- handle (knob role, the slider)
States
- rest
- focus (handle ring)
- dragging (handle 8% larger at once, divider follows the pointer)
Keyboard
- Arrows move 1% (Shift 10%)
- Home / End
Motion
Divider follows the pointer or key with no easing; the handle grows at once when grabbed and settles over --pui-motion-out when released.

More in Content & display
- Advertisement: A sponsor or promo slot that turns through its ads on a hairline that fills; hovering or focusing holds the current ad.
- Avatar: A person or account in a small space: a photo, or initials on the hue their name always gets; presence dot; circle for people, square for companies.
- Avatar group: A team in a small space: overlapping faces that name themselves on hover or focus, and “+N” naming the rest.
- Badge: A short status, category or count label: six tones, an icon or a status dot, two sizes.
- Code block: Code to read and copy: highlighted in the system's colours, numbered, marked lines, long files folded behind “Show all”.
- Comment thread: A discussion attached to something: replies, reactions, @mentions, editing and deleting your own, resolve that folds the thread.
- File diff: A change to one file as a unified diff: line numbers, tinted lines, only the changed words marked, long unchanged stretches folded; give rows or just…
- Item: The generic list row: media, title, description, meta and trailing actions; becomes a link or button when interactive.
- Kbd: Keyboard keys as keycaps; `mod` resolves to ⌘ or Ctrl per platform, symbols are spoken as words.
- Lightbox: A full-screen image viewer: a thumbnail grows into it and shrinks back, arrows and ←/→ step through the set, Esc or a downward drag closes it.
- Logo Carousel: A wall of logos shown a few at a time: every few seconds the slots turn left to right, each logo leaving upward as the next rises in.
- Marker: A labelled point in a stream: a status event with an icon between messages, or a label such as "Today" between two hairlines.
- QR Code: A scannable code set as gradient dots with rounded finder rings and an optional centre mark; a new value ripples out from the centre.
- Slot text: Text and numbers that roll into their new value on reels, digit by digit from the right; other characters fade. Read as plain text by assistive tech.
- Text morph: A short label that becomes its next state letter by letter: shared letters glide into place, new ones arrive, old ones leave.
- Text reveal: A headline whose words rise into place once, the first time it scrolls into view; never repeats.
- Text shimmer: Ongoing work said in words (“Thinking…”) with a calm band of light passing across them; stops when inactive.
- Timeline: What happened, newest first and grouped by day: people with avatars, systems with toned icons, relative times with the exact time on hover, details in…
- Video player: A video player on the native <video> element: title bar with an external link and close, centre play with ±10 s, scrub, time, volume, speed, captions…
