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	Line height for the text shape, diameter for circle.
data-ui-shape	text · circle · media	text	Placeholder geometry.
data-ui-width	full · medium · short	full	Inline size, so a group of lines can look like real text.

Styling

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

This component adds no custom properties of its own. Restyle it through the design tokens or your own CSS.

Design tokens this component reads (6)

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

--ui-bg-surface-raised · --ui-ease-standard · --ui-fg · --ui-radius-lg · --ui-radius-pill · --ui-radius-sm

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.
