Anatomy

Parts are authored in your own markup and identified by the selector below, so your CSS can target the same anatomy without loading Timeless styles. Required parts must be present for the component to work. Private data-ui-internal-* hooks are written by the runtime and must never be authored.

Part	Required	Selector	Purpose
hint	No	[data-ui-part~='hint']	Supporting text or the live <output> value.

Attributes

Every value below is implemented by the stylesheets this component ships. Boolean attributes are presence-based: author the attribute with no value, or omit it.

Attribute	Values	Default	Description
data-ui-size	sm · md · lg	md	Track thickness, thumb diameter, and label size.

State

Native attributes, ARIA, and platform pseudo-classes are authoritative. Style state through the selectors below rather than adding your own state classes.

State	Source	How to express it
invalid	native	Native :invalid, or aria-invalid="true".
disabled	native	Native disabled.

Styling

Root identity: ui-range. Required stylesheets: tokens.css, range.css.

Set these custom properties to restyle the component:

Custom property	Controls
--ui-range-track	Track thickness.
--ui-range-thumb	Thumb diameter.

Design tokens this component reads (8)

These are global Atmosphere tokens. Change them once at the theme level rather than per component.

--ui-bg-surface · --ui-fg · --ui-fg-muted · --ui-font-mono · --ui-line-strong · --ui-radius-pill · --ui-shadow-control · --ui-space-2

Accessibility

Keep the native elements, roles, and relationships shown in the example. Timeless adds only the state and keyboard coordination the platform does not already provide, and it never supplies your accessible names — those depend on your content.

Before JavaScript runs

This primitive is CSS only. There is nothing to register and nothing to wait for.
