Windowed schedule grid
Rows of resources against a fixed time window, where each block is sized by its overlap with the window rather than by its own duration.

A UI pattern library built for coding agents. 40 patterns, each shipping a copy-paste prompt that rebuilds it inside your own codebase — plus a live preview and the source behind it.

40Patterns
The pattern running live in an isolated frame, in whichever theme you are reading in.
Its markup, styles and behaviour, plus a single runnable file carrying its own palette.
A written spec that rebuilds the pattern from scratch — including why each decision is the way it is. Paste it into Claude Code, Cursor, or any coding agent.
The prompts are the point. Each one is written to survive being handed to an agent with no other context: it names the surfaces the pattern belongs on, spells out the constraint that makes it work, and calls out the failure it exists to prevent. Nothing here is a dependency you install.
Rows of resources against a fixed time window, where each block is sized by its overlap with the window rather than by its own duration.
Places a raw figure on a scale of external benchmarks instead of printing it plain.
A two-axis lookup table with both headers sticky, hover lighting the full row and column at once, and a durable click-to-pin selection for touch.
Shortens a long path by dropping whole segments from the left, because the tail is what tells two paths apart.
A sequence compressed into a row of small marks whose shape carries the state.
A month-by-month volume timeline built from plain divs where every aggregate row links to the filtered view that produced it.
A vertical potion-vial meter whose liquid fills a wide bulb first and then rises into a narrow neck — all CSS, no images.
Progress for work with several possible endings, drawn as a census rather than a fraction.
A computed figure shown with the audit trail behind it — the number is the product and the derivation is the receipt.
A dry run shown as a before-and-after tree with counts now, after, and the difference.
One card shell many independent sources render through, where the shell does the capping.
Where a record stands for a physical thing, the card is drawn as that thing — nine variations in pure gradients.
A container with no artwork draws one from up to four member tiles, grid tracks following tile count.
Text printed over unreviewed artwork, scrimmed to an alpha that can be written down rather than guessed.
Stat tiles joined by hairlines that are grid gap, not borders.
Conversation bubbles with a speaker-colored spine and a fixed metadata gutter.
Pinned paper notes on a cork board where every texture is layered CSS gradients.
Markers at percentage coordinates over a fixed-aspect picture, turning into a list when too narrow.
Inline drawings for empty surfaces stroked in the inherited text colour.
Cards flowing down columns instead of across rows, with the reading-order cost stated plainly.
An inset shadow shown only on the edge that has more content behind it.
A one-card-at-a-time review queue whose batch is snapshotted at mount.
Per-card controls over a fully-linked card without nesting interactive elements in the anchor.
One canvas, a registry of draw modes, each mode owning its entire frame.
A dense grid of state cells that is one tab stop with arrow-key navigation.
Sticky vertical rail on wide screens, wrapping tab row on narrow ones, from the same markup.
Buttons on a solid ledge shadow that travel down onto it when pressed.
A blocked control stays focusable, carries the reason as text, and refuses in its handler.
One card for every state a background job passes through.
FLIP-style motion between two rendered states when the old DOM is already gone.
Assignment that starts at the destination slot, then narrows the catalogue.
A destructive action with no confirm dialog, held behind a toast and committed when it expires.
New
A confirm dialog that names everything a delete cascades and blocks dismissal while it runs.
A bar that exists only while something is selected, states the count in words, caps at five actions.
The three empty states a list actually has, written as three different screens.
A search box that echoes back how it read the text as removable chips.
One grouped select whose value carries both the kind and the id.
Colors solved against the page's own ground token so they invert correctly between themes.
One custom property carries the hue; border, fill, spine and dot derive from it.
Opaque controls, a gradient-darkened fill, and a two-tone focus ring on a surface whose colour arrives from outside.
