h2Featuresh2

h2Featuresh2 is a hypothetical feature set designed to improve the handling of second-level headings (h2) in web content. It provides tooling to manage, style, and semantically annotate h2 elements to enhance document structure, accessibility, and consistency across pages and sites.

Core features

- Semantic control: optional ARIA roles, automatic or manual heading level association, and support for document outlines.

- Automatic numbering and outlining: hierarchical numbering, generation of outlines or table of contents.

- Design tokens and styling: typography, spacing, and color tokens applied consistently to all h2 instances.

- Accessibility enhancements: improved focus visibility, skip-to-content integration, and consistent keyboard navigation.

- Editor and CMS integration: plugins for popular editors and components for inline editing.

- API and customization: configuration hooks, events for rendering changes, and framework-agnostic utilities.

Use cases

These features support documentation portals, corporate sites, educational platforms, and technical blogs that require consistent heading semantics and accessible navigation, as well as offline or generated content workflows where structure consistency is important.

Implementation notes

For developers, h2Featuresh2 can be delivered as a JavaScript library, a set of framework components, or a backend rendering utility. It typically exposes an initialization method, a configuration object, and small utilities to query or mutate heading behavior. Performance considerations include minimizing reflows and providing opt-out flags for pages with custom heading structures.

Standards and compatibility

The approach emphasizes HTML5 semantics, ARIA best practices, and WCAG guidance related to headings and keyboard navigation. It aims for broad browser support with sensible fallbacks for legacy environments.
