Heading is intended to be used to define the title of the page. They are displayed as h1 by default. Accessibility requires having just one h1 tag on the page. Keep that in mind during the implementation.

Import

import { Heading } from '@contentful/f36-components';
// or
import { Heading } from '@contentful/f36-typography';

Examples

Margins

Forma 36 typography components provide a way to set their own margins. By default Heading component has a margin bottom of 1rem (16px). You can override the default margin bottom by specifying it explicitly on the component level by marginBottom="none" or any other value from our spacing options

as property

For some cases, you might have to use Heading in a different context than the page title. For that we provide you with as property, to allow you to set the tag of the component to another tag than h1

Truncated text

Sometimes you might have to truncate the text in the Heading component, so we provide the prop especially for that. Under the hood, what it does is add overflow: hidden and set text-overflow to ellipsis. Have a look at the example below:
