@hairline

The base action: variants, 24–40px sizes, a 3% press, and status (pending, success, error) shown through an icon slot and a morphing label.

Connected actions on one surface: a selection fill that is thrown to the segment you pick, dividers that fade beside it, labels that fold into icons when narro…

Dual-action trigger: primary action on the left, trailing chevron on the right opening an aligned dropdown menu.

Copies on the press: the icon blurs into a self-drawing check, the label morphs to Copied, and a failed copy shakes and says so.

A button that runs a promise and shows it: the icon slot opens for a spinner, a check draws itself, failures shake, and the label morphs through each.

Icon toolbar where the action you point at, tab to or tap opens its label while neighbours slide aside, with ask-first and done states in place.

Floating canvas toolbar: one indicator thrown to the active tool, a zoom stepper whose value rolls, and a menu that grows out of its chevron.

One icon becoming another: blur pop, direction-aware turn, card flip, or strokes that draw themselves. Fast toggling never jumps.

A one-line field with a label, hint and error that trade places, a clear button that folds in, and one shake when an error arrives.

A text box that eases to the height of what you write, scrolls with its own thin thumb and faded edges, and turns into a composer with tools, a send button and…

A password field with an eye that turns into eye-off, a four-step strength meter that fills and names itself, and a Caps Lock warning.

The field at the top of every list: ⌘K focuses it from anywhere, search runs after a pause, the magnifier blurs into a spinner while it loads.

A choice from a list that is never the browser's dropdown: the pill grows into its list and folds back as the label morphs.

Several choices from a short list: the pill names them ("Design, Sales +2"), the list rises off it with ticks that draw, and it stays open while you pick.

One date, typed or picked: the field reads "tomorrow", "next fri" or "4 nov", and the calendar slides by month while one mark glides between days.

A real checkbox whose fill grows from the centre and whose tick draws itself, with a mixed state that bends into the tick.

One choice from a few: the dot pops into the new circle, or, as cards, one selection frame glides from card to card.

A switch with weight: the thumb stretches on press, is thrown across with a slight overshoot, and spins while an async save settles.

One value or a range: a press throws the nearest thumb there, a drag tracks the finger, and the value rises out of the thumb.

One of a few options side by side: the thumb is thrown to the new segment while its width eases to the new label.

A name and shortcut for an icon. The first one waits; after that they glide from trigger to trigger like one label travelling along the toolbar.

A small panel that belongs to a button: it rises off the trigger from the nearest point, flips to fit, and hands focus to what is inside.

A preview of what a link points to: it rises off the link after a rest, stays open while you move onto it, and closes after a short grace.

Actions behind a button: the menu rises off the trigger, one highlight glides between rows, and checkbox rows draw their tick in place.

Actions where you right-click: the menu grows from the exact point, a long press opens it on touch, and Shift+F10 from the keyboard.

A decision that needs the whole screen: the page fades back under a veil of its own colour and the panel rises out of a blur.

A panel that slides in from an edge and can be thrown back: drag it toward its edge and release speed decides whether it closes.

A status, a tag or a count: statuses ease their colour and morph their word, live dots breathe, counts roll and fold away at zero.

A face, or initials until there is one: the photo rises out of a blur once it has loaded, and a stack of avatars fans open when you point at it.

Something is happening: a ring with one sweeping arc, three rising dots, or eight petals fading round, in currentColor.

How far along, as a bar or a ring: the fill eases to each value, the percent rolls, and at 100 it turns green and a check draws itself.

The shape of what's coming, with one soft band of light sweeping across, and a swap that hands over to the real content without a pop.

What a list says before there is anything in it: an isometric line drawing in your theme that draws itself, changes with the state and acts out the action.

A message that sits in the page: its tint, line and icon ease when the tone changes, and dismissing folds it away so the content below slides up.

A keyboard shortcut written for the reader's keyboard (⌘ on a Mac, Ctrl elsewhere) whose keys sink when you press them for real.

Views of one thing: the underline or pill is thrown to the new tab, the panel slides in from the side you moved toward, and counts roll.

Sections that open in place: the height eases open, the content rises out of a blur a beat later, and opening one folds the other at the same time.

"Show 4 more" that opens in place: the hidden part eases open through a blur while the button's words morph to "Show less".

Where you are and the way back: a long trail folds its middle into "…", which opens the hidden crumbs in place one after another.

Pages of a long list: the current-page mark is thrown to the new number, and in a narrow container it becomes "3 of 12" with a number that rolls.

On/off choices side by side whose fills merge: two pressed toggles next to each other square off their inner corners and read as one shape.

Where you are in a flow: the line to the next step fills along its length, the finished number blurs into a drawn check, and phones get "Step 2 of 4".

Text that changes the way it should: shared letters slide over, new ones rise out of a blur, the width eases.

Save, Saving, Saved: the spinner opens in, the check draws itself, errors shake, and the label morphs between them.

Numbers that change like an odometer: every digit rolls in the direction the number moved.

Monthly or yearly: the thumb slides with a little give, and every price on the page rolls to its new amount.

An email field that becomes its own answer: the button stretches across it, then settles as "You’re on the list · #1,248".

The six boxes, done properly: digits rise in, a paste cascades, a wrong code shakes and clears, the right one becomes a pill with a check.

A multi-step form in one card that changes shape: steps slide in from the way you’re going, checks shake and explain, and Create turns into what comes next.

A range is one liquid band: it follows your pointer between days, presets flow it to their span, and the dates morph as it moves.

One dropdown that follows you along the menu, gliding and resizing to each item’s content.

One panel, many features: the line slides between tabs, fills as autoplay runs, and the panel eases to each.

A how-it-works section that tells itself as you scroll: steps light up at the middle, a rail fills, and one card reshapes into each step’s picture.

Numbers that arrive when you do: hairlines draw themselves, then each figure rolls up from zero in turn.

"New: …" above your headline that opens into the news: the pill itself grows into a changelog card.

One quote, chosen by its people: faces step forward, the words cross-fade through a blur, a ring keeps time.

Questions on hairlines that open like they mean it: the answer eases to its height, the plus folds into a minus.

A quiet strip of logos that notices you: it eases to a stop on hover and the logo you point at stays bright.

An image opens from its exact place in the grid, becomes a spacious viewer, and finds its way back.

A tactile stack that fans out, follows your hand, and deals the next card with a measured flick.

Connected steps you can move, inspect and follow as work flows through them.

Two images, one precise divide. Drag to reveal what changed, then let the handle settle.

A dock that makes room for the tool you reach for, then opens it in place.

A deliberate action, held for a moment: the ring fills, the label changes, and confirmation settles into a check.

A list row that slides over its actions: cells grow with your finger, a full swipe runs the first one, and the row folds away.

A considered file uploader. Clear actions, quiet progress and useful feedback.

A drop zone whose border is a membrane: it reaches for the file, holds it, swallows it and passes it through to its row.

Drums you can fling: each column is a real cylinder that decays onto a row, with a lens in full colour over the middle.

Bars, line and area as one set of marks: bars condense into beads, a thread is strung through them, the fill pours down. Drag the switch to scrub it.

Two hairline needles across a graduated scale. Thumbs glide without layout thrash and repel each other on contact.

A multi-segment allocation track. Drag dividers to rebalance constrained percentages with zero initial jump.

A desktop-grade resizable dual panel. Zero-lag drag, rubber-band spring limits, and double-click preset snapping.

The invite field, done properly: typed letters grow a chip round themselves, pasted lists spill out of the caret, and a duplicate flies into its twin.

The profile photo field without a modal: the avatar itself grows into the crop, and shrinks back with the face you framed.

A scheduling week you hold in the hand: drag a slot into an event while its times roll, and anything it lands on eases aside.

Rename a title, a project or a row where it stands: the text becomes the field without moving a pixel, and saves itself.

Pick one or several from a list your server searches: results morph between queries instead of flashing, and picks fly into chips.

A schedule field people can read: cron or plain English in, the meaning in words and the next runs out, with clock changes flagged.

"Last 15 minutes" for logs, metrics and traces: type 2h or yesterday 14:00–16:00, step by the window, pause live, or drag across a chart to zoom.

Read, search and quote a webhook payload or an API response, or see exactly what changed between two versions of a record.

A tactile incrementer: tap to step, hold to accelerate, bounds give an elastic bumper shake, and digits roll in place.

An ultra-compact inline trendline with magnetic scrubber and auto-trend color for table cells and stat cards.

A frosted optical unmasker for sensitive keys, salaries and tokens, with auto-hide timeout and one-tap copy.

A table whose rows travel: sort and every row glides to its rank, live data re-ranks itself, and selection turns the toolbar into its actions.

A pipeline you rearrange by hand: the card becomes the stage it's over while still in the air, and every column's total rolls as it passes.

The bar above a list, done like Linear’s: one panel from property to value, chips you change in place, and a sentence that becomes filters.

The sidebar of pages, folders or files: carry a row up, down and sideways to nest it, and folders open as you hold them.

Review threads beside the text they quote: the one you choose lines up with its line, and the rest make way.

The API keys screen, done properly: the secret rises in once, and Done folds it down into the "sk_live_••••4f2a" it leaves behind.

One pill for whatever is happening now: it updates in place, tap it and it grows into a panel, done blurs into a check.

The sun sets into a moon, and the new theme spreads from the button in a circle.

Drag to your size and watch the price roll, the plan morph and, at the top, “Let’s talk”.
