Toast open / close

When to use

Toasts, snackbars, and transient confirmations that rise into view from the bottom edge — "Saved", "Copied", "Message sent". The toast translates up with a fade, a slight scale, and a cross-blur; opening runs on the slower open clock while dismissing uses the faster close clock, so arriving feels deliberate and leaving feels snappy.

Use toast when the surface announces itself and goes away on its own; use modal when the user must respond before continuing.

HTML usage

html
<div class="t-toast" data-open="false"> … </div>

Toggle .is-open on the toast. It rises from below with a fade + cross-blur + slight scale; opening uses the slower open clock, the resting (closed) transition uses the faster close clock, so a single class gives the open/close asymmetry.

Tunable variables

The :root defaults below match the live tuning on transitions.dev. Drop them into your global stylesheet once — every transition in this skill reads from semantic names like these, so multiple transitions can share a single :root block.

css
:root {  --toast-open: 350ms;  --toast-close: 250ms;  --toast-distance: 16px;  --toast-blur: 2px;  --toast-scale: 0.97;  --toast-ease: cubic-bezier(0.22, 1, 0.36, 1);}

CSS

css
.t-toast {  opacity: 0;  transform: translateY(var(--toast-distance)) scale(var(--toast-scale));  filter: blur(var(--toast-blur));  will-change: transform, opacity, filter;  transition:    opacity var(--toast-close) var(--toast-ease),    transform var(--toast-close) var(--toast-ease),    filter var(--toast-close) var(--toast-ease);}.t-toast.is-open {  opacity: 1;  transform: translateY(0) scale(1);  filter: blur(0);  transition:    opacity var(--toast-open) var(--toast-ease),    transform var(--toast-open) var(--toast-ease),    filter var(--toast-open) var(--toast-ease);}
@media (prefers-reduced-motion: reduce) {  .t-toast { transition: none !important; }}

The @media (prefers-reduced-motion: reduce) guard at the bottom of the snippet is required — keep it. It zeroes the transition for users who have asked for less motion at the OS level.

JavaScript orchestration

None — pure CSS. Toggle the documented HTML attributes or class names from whatever already drives state in your app.
