`Heading`¶

Create an explicit heading level without inferring document hierarchy.


Import	`from hedron import Heading`
Distribution	`hedron`
Backend activity	No
Normal render mode	`RenderMode.FRAGMENT`

Live demo¶

Production

Deployment history

Heading level two introduces this section.

The preview is a local docs simulation (not a running Hedron server). Interactive demos show a “Simulated HTMX” trace when applicable.

Basic use¶

from hedron import Heading

component = Heading('Deployment history', level=2)

Compose under Page for full documents, or return from a fragment route for HTMX swaps.

How it works¶

The requested level maps directly to h1 through h6. Hedron does not guess levels because reusable components need their caller to own document structure.

This component's core behavior is server-rendered HTML and does not require a browser runtime. The preview is ordinary semantic HTML, so keyboard, form, link, and disclosure behavior comes from the platform.

Constructor and parameters¶

Heading(content='', *, level=2)

Parameter	Type	Meaning
`content`	`str`	Escaped heading text.
`level`	`1 \| 2 \| 3 \| 4 \| 5 \| 6`	Exact native heading level.

Composition and backend behavior¶

Keep Heading at the smallest semantic boundary. Fragment routes should return only the replaced region and preserve stable target IDs across success, validation, empty, loading, and error responses.

This component is primarily presentational; keep any mutation on an explicit action or component route.

Accessibility¶

Do not skip levels merely for appearance; style headings with CSS and preserve a logical outline.

Security¶

Escaping and SafeUrl / TrustedHtml are framework concerns; authorization and data exposure remain application code. Redact secrets before rendering.

Common mistakes¶

A page should generally have one descriptive level-one heading.
Do not copy docs-preview JavaScript into an application server.

Testing¶

from hedron import RenderMode, render

result = render(component, mode=RenderMode.FRAGMENT)
assert result.html
assert not result.diagnostics
