1# Span 2 3As a child of the [\<Text>](ts-basic-components-text.md) and [\<ContainerSpan>](ts-basic-components-containerspan.md) components, the \<Span> component is used to display inline text. 4 5> **NOTE** 6> 7> This component is supported since API version 7. Updates will be marked with a superscript to indicate their earliest API version. 8> 9> Since API version 10, this component can inherit the attributes of the **\<Text>** parent component. That is, if no attribute is set for this component, it inherits the attributes (if set) of its parent component. Only the following attributes can be inherited: **fontColor**, **fontSize**, **fontStyle**, **fontWeight**, **decoration**, **letterSpacing**, **textCase**, **fontfamily**, and **textShadow**. 10 11 12## Child Components 13 14Not supported 15 16 17## APIs 18 19Span(value: string | Resource) 20 21Since API version 9, this API is supported in ArkTS widgets. 22 23**Parameters** 24 25| Name| Type| Mandatory| Description| 26| -------- | -------- | -------- | -------- | 27| value | string \| [Resource](ts-types.md#resource) | Yes| Plain text.| 28 29 30## Attributes 31 32Only the [universal text attributes](ts-universal-attributes-text-style.md) are supported. 33 34| Name| Type| Description| 35| -------- | -------- | -------- | 36| decoration | {<br>type: [TextDecorationType](ts-appendix-enums.md#textdecorationtype),<br>color?: [ResourceColor](ts-types.md#resourcecolor)<br>} | Style and color of the text decorative line.<br>Default value: {<br>type: TextDecorationType.None<br>color: Color.Black<br>} <br>Since API version 9, this API is supported in ArkTS widgets.| 37| letterSpacing | number \| string | Letter spacing. A negative value tightens the spacing; a positive value loosens the spacing, and the letters are spread farther apart with the value.<br>Since API version 9, this API is supported in ArkTS widgets. | 38| textCase | [TextCase](ts-appendix-enums.md#textcase) | Text case.<br>Default value: **TextCase.Normal**<br>Since API version 9, this API is supported in ArkTS widgets.| 39| font<sup>10+</sup> | [Font](ts-types.md#font) | Text style, covering the font size, font width, Font family, and font style.| 40| textShadow<sup>11+</sup> | [ShadowOptions](ts-universal-attributes-image-effect.md#shadowoptions) \| Array<[ShadowOptions](ts-universal-attributes-image-effect.md#shadowoptions)> | Text shadow.
