Textblock

Design System - Textblock component

The Text Block component provides a structured typographic layout, combining various levels of hierarchy such as headings, subheadings, captions, and descriptions. It ensures clarity, consistency, and adaptability in presenting textual information across different screens and use cases.

Component React

// Sample code
<TextBlock caption="Note" header="Important Information" subHeader="Please read carefully" body="Make sure to follow the guidelines." wrapperClassName="custom-wrapper" captionClassName="custom-caption" headerClasName="custom-header" subHeaderClasName="custom-subheader" bodyClasName="custom-body" />

Anatomy

Variants

---

	Default The default Text Block displays a structured combination of a caption, heading, subheading, and description. Each section can be individually toggled on or off based on the context or content requirement.

---

Properties

Heading Label Displays a prominent title or main heading. Turning this off removes the main visual anchor of the text block.
Subheading Label Adds supporting information below the heading. Can be turned off to simplify the text hierarchy.
Caption Label Offers a small label above the heading, often used for categorization or section labeling.
Description Label Provides a detailed explanation or contextual information below the subheading. Turning it off results in a more compact block.

Property Configuration Table

Each design component offers a range of configurable options. These options are intentionally platform-agnostic, allowing implementations to adapt and tailor them to align with the specific requirements of the chosen framework.
