The <Heading> component creates semantic heading elements with appropriate default sizes and styling. It ensures proper heading hierarchy while providing visual consistency.

jsx

<Heading as="h1">Page Title</Heading>
<Heading as="h2">Section Title</Heading>
<Heading as="h3">Subsection Title</Heading>

Semantic Heading Levels

Use the required as prop to specify the semantic heading level. Each level has a default size that follows standard typography hierarchy.

<Storybook.Demo> <Storybook.SideBySide vertical> <Heading as="h1">Heading 1</Heading> <Heading as="h2">Heading 2</Heading> <Heading as="h3">Heading 3</Heading> <Heading as="h4">Heading 4</Heading> <Heading as="h5">Heading 5</Heading> <Heading as="h6">Heading 6</Heading> </Storybook.SideBySide> </Storybook.Demo>

<Heading as="h4">Heading 4</Heading>
<Heading as="h5">Heading 5</Heading>
<Heading as="h6">Heading 6</Heading>

Custom Sizes

Override the default size with the size prop to decouple visual appearance from semantic meaning.
