Component Guide

import { Heading } from '@uhg-abyss/web/ui/Heading';

Usage

The Heading component is used to create headings in your application. It supports different levels, sizes, and styles based on the brand (Optum or UHC). It follows our Typography guidelines to ensure consistency across the application.

Level

If you want to set the heading level, you can provide a level prop. This will allow you to set a specific heading level (1-6). The default is 1.

Size

The size prop controls the visual size of the heading typography.

• Optum: 'xxl' | 'xl' | 'lg' | 'md' | 'sm' | 'xs' | 'xxs'

The default is xl.

Color

Use the color prop to set the color of the text. This prop accepts any valid CSS color identifier (RGB, HSL, named color, etc.) as well as Abyss color tokens. The default value is '$web.semantic.color.text.content.primary'.

Color contrast

Text colors must meet the minimum 3:1 contrast ratio for large text as per WCAG 2.1 guidelines.

Text alignment

Use the textAlign prop to control the horizontal alignment of the heading text. Available values are 'left', 'center', and 'right'. The default alignment is 'left'.

Nesting heading levels

Using Heading.Level

Nesting headers with the Heading.Level subcomponent allows users to have multiple levels of headers, without having to directly tag each level of <h*> tags. It also automatically adjusts the size.

Using level and size

Alternatively, users can set the level and size props on a Heading to achieve the same effect.

Nesting example

Nested headers can be combined together with text to organize sections and create a seamless document experience.
