CSS Dates & Time Effects

Contribution grid filled column-first with `grid-auto-flow`, so weeks run down and the whole thing stays one flat list of cells.

Listing led by a tear-off date block in a real `<time>`, so the day and month are one semantic unit rather than two decorated spans.

Two dates joined by an en-dash inside one focus ring, with quick presets underneath because most range picks are a common span, not an arbitrary one.

Timer that empties rather than fills, the sweep animated through a registered angle property so the arc interpolates smoothly instead of snapping between conic stops.

Hour rail with events sitting in the slots they occupy and an empty hour left visibly empty, the current-time rule crossing the whole column with a dot on the gutter.

Date field opening a month grid anchored beneath it, leading days from the previous month dimmed rather than blank so the week rows stay aligned to their columns.

Fixed day/month/year segments that take focus one at a time and auto-advance, so the separators are chrome the user never has to type.

Upper cone draining and lower cone filling on matched clip-path keyframes, the whole body turning over only once the sand has run through.

Month-view placeholder with a header, amber weekday ticks, a 7-by-4 grid of day cells and a highlighted today dot.

Split-flap digit cards whose top half hinges forward on its axis and falls out of sight, the way a station clock turns over.

Booking grid with resources down the side and hours across the top, each reservation drawn as a block spanning its slots.

Analogue clock face with hour ticks and three hands, the red second hand stepping round in sixty discrete jumps.

Outline that draws itself edge by edge around the panel on a four-second cycle, the way a countdown ring reads on a rectangle.

Seven day cells reading a week at a glance — filled for done, outlined red for missed, and a dashed pulse on the day still open.

A drum of month labels standing on a 3D cylinder, fading as they curve away from the lit selection band, and rolling on by one notch when hovered.

A framed hourglass whose upper chamber empties through a thin stream into the heap below, and once the sand has run through the whole frame turns over to start again.

Remaining time read as sand rather than a bar — the level in the top cone drops while the heap in the bottom one builds, with a dashed grain stream falling through the waist and the whole glass turning over on hover.
