# TextBlock Text block is used to render a block of text that occupies the full width available, like a paragraph. ```tsx import { reactExtension, TextBlock, BlockStack, } from '@shopify/ui-extensions-react/checkout'; export default reactExtension( 'purchase.checkout.block.render', () => , ); function Extension() { return ( We have a 30-day return policy, which means you have 30 days after receiving your item to request a return. To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. ); } ``` ```js import { extension, TextBlock, BlockStack, } from '@shopify/ui-extensions/checkout'; export default extension('purchase.checkout.block.render', (root) => { const textBlock = root.createComponent(BlockStack, undefined, [ root.createComponent( TextBlock, undefined, 'We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.', ), root.createComponent( TextBlock, undefined, 'To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase.', ), ]); root.appendChild(textBlock); }); ``` ## TextBlockProps ### TextBlockProps ### appearance value: `Extract< Appearance, | 'accent' | 'subdued' | 'info' | 'success' | 'warning' | 'critical' | 'decorative' >` Changes the visual appearance ### emphasis value: `Emphasis` Use to emphasize a word or a group of words. ### id value: `string` A unique identifier for the component. ### inlineAlignment value: `InlineAlignment` Align text along the main axis. ### size value: `TextSize` Size of the text ## Related - [Heading](heading) - [HeadingGroup](headinggroup) - [Text](text)
