/** * toggle.css: Toggle (.ui-toggle), a button-styled checkbox/radio * * Same look as .ui-button (tokens default to the --ui-button-* family), but it wraps a * native checkbox or radio inside a <label>. State is driven from the nested input * via :has(): the checked state reuses the button's *active* token values, so an * "on" toggle reads like a pressed button. * * @layer      variables, components * @requires   layers.css, _variables.css, button.css * @uses       :has(): drive label state from the nested input (checked/focus/disabled) * @uses       oklch(from …): variant hover/active tints (inherited from --ui-button-*) * @uses       text-box: vertical trim (patchy browser support) * @tokens     --ui-toggle-* (@layer variables; default to the --ui-button-* family) * @consumedby toggle-group.css * @see        https://ui.shadcn.com/docs/components/base/toggle */@layer variables {  :root {    --ui-toggle-ring-color: var(--ui-button-ring-color);    --ui-toggle-font-family: var(--ui-button-font-family);    --ui-toggle-font-size: var(--ui-button-font-size);    --ui-toggle-font-weight: var(--ui-button-font-weight);    --ui-toggle-line-height: var(--ui-button-line-height);    --ui-toggle-background: var(--ui-button-background);    --ui-toggle-background--hover: var(--ui-button-background--hover);    --ui-toggle-background--active: var(--ui-button-background--active);    --ui-toggle-background--checked: var(--primary);    --ui-toggle-background--checked-hover: oklch(from var(--primary) l c h / 0.9);    --ui-toggle-background--checked-active: oklch(from var(--primary) l c h / 0.8);    --ui-toggle-foreground: var(--ui-button-foreground);    --ui-toggle-foreground--hover: var(--ui-button-foreground--hover);    --ui-toggle-foreground--active: var(--ui-button-foreground--active);    --ui-toggle-foreground--checked: var(--primary-foreground);    --ui-toggle-foreground--checked-hover: var(--primary-foreground);    --ui-toggle-foreground--checked-active: var(--primary-foreground);    --ui-toggle-border: var(--ui-button-border);    --ui-toggle-border--hover: var(--ui-button-border--hover);    --ui-toggle-border--active: var(--ui-button-border--active);    --ui-toggle-border--checked: 1px solid var(--primary);    --ui-toggle-border--checked-hover: 1px solid var(--primary);    --ui-toggle-border--checked-active: 1px solid var(--primary);    --ui-toggle-gap: var(--ui-button-gap);    --ui-toggle-padding: var(--ui-button-padding);    --ui-toggle-height: var(--ui-button-height);    --ui-toggle-radius: var(--ui-button-radius);    --ui-toggle-icon-size: var(--ui-button-icon-size);    /* composes into the toggle's box-shadow list: use a transparent shadow,       never `none`, so the focus ring layers stay valid */    --ui-toggle-shadow: var(--ui-button-shadow);  }}@layer zazz.components {  /* ===========================================================================  TOGGLE  Markup: a <label class="toggle"> wrapping a visually-hidden  <input type="checkbox"> (or "radio") and the visible content.
