Usage

Text renders styled body text and headings from the theme. Use XDSText with a semantic type for body copy, labels, and captions, and XDSHeading for section titles that output the correct h1–h6 element.

Best practices

Guidance	Practices
Do	Pick a semantic type (body, label, supporting, large, code) instead of manually setting size and weight — the theme handles the details.
Do	Set accessibilityLevel on XDSHeading when the visual level differs from the document outline so screen readers announce the correct hierarchy.
Do	Use maxLines with a number to truncate long content — a tooltip appears automatically on hover so no text is lost.
Do	Enable hasTabularNumbers for columns of numeric data so digits align vertically across rows.
Don't	Override size and weight when a semantic type already matches — extra overrides fight the theme and break when themes change.
Don't	Skip heading levels in the document outline — go h1 then h2 then h3, never h1 then h3.
Don't	Use raw HTML tags like <p>, <h1>–<h6>, or <span> for text — XDSText and XDSHeading apply the correct theme tokens automatically.

Import

ts
import {XDSHeading} from '@xds/core/Text'

Props

Prop	Type	Description
levelrequired	1 \| 2 \| 3 \| 4 \| 5 \| 6	Visual heading level. Determines both the HTML element (h1–h6) and the styling from the theme.
childrenrequired	ReactNode	Heading content.
accessibilityLevel	1 \| 2 \| 3 \| 4 \| 5 \| 6	Accessibility level override. When set and different from `level`, applies `aria-level` so the document outline differs from the visual style.
color	'primary' \| 'secondary' \| 'disabled' \| 'placeholder' \| 'active' \| 'inherit' (default: 'primary')	Text color.
display	'inline' \| 'block' (default: 'block')	Display type. Silently overridden to 'block' when maxLines > 0 or hasCapsize is true.
maxLines	number (default: 0)	Maximum lines before truncation. 0 means no truncation. When set, shows a tooltip on hover if content is truncated.
hasTruncateTooltip	boolean \| LayerPlacement (default: true)	Controls tooltip behavior for truncated text. true shows the tooltip at the default position, false disables it, or a LayerPlacement string sets a specific position.
wordBreak	'break-word' \| 'break-all'	Word break behavior when truncating. Defaults to 'break-all' for single-line truncation, 'break-word' otherwise.
textWrap	'wrap' \| 'nowrap' \| 'balance' \| 'pretty'	Text wrapping behavior.
hasCapsize	boolean (default: false)	Enable optical alignment using text-box-trim. Forces block display.
hasStrikethrough	boolean (default: false)	Apply strikethrough text decoration.
id	string	HTML id attribute.

          <XDSText type="body" maxLines={2} display="block">
            This is a card description that might be quite long and needs to be
            truncated after two lines to keep the card compact and uniform.
