# Nature Section Heading

The Nature Section heading is a type of heading used for titles of some subsections of pages on Nature.com.

It uses borders to make it stand out from other headings on the page.

## When to use this component

Use the Nature Section heading when you want to organise multiple pieces of content into a section on a landing page. For example, a group of cards linking to articles on a similar subject.

## When not to use this component

When you need to break up content on article pages into chunks, use [default heading styles](https://frontend-design-system.private.springernature.app/nature/styleguide/typography#headings-nature-journals).

## How it works

Write clear, descriptive headings using sentence case.

### Section headings with and without a top border

There are 2 styles of Section heading:

- one with a top and botton border - this is set as an `<h2>` heading level
- one with a bottom border and no top border - this is designed for sub-headings and is set at heading level `<h3>`

If you need to change the default heading level of a Section heading, you can do this using the heading level with the `aria-level` property. The level should be a string, not an integer.

To make our sites accessible, you must always [use heading levels correctly to communicate page structure](https://elements.public.springernature.app/nature/styleguide/typography#use-heading-levels-to-communicate-page-structure).

### Section headings as links

You can use a Section heading to link to another page.

If you're using the handlebars template and you add a link, the heading will render a chevron after the heading text to show users that they can click on it.

If you're not using the handlebars template, you'll need to style it yourself using [the source code for the chevron svg icon](https://github.com/springernature/elements/blob/master/context/themes/springernature/img/icons/chevron-right.svg
).
