Description

Usage
The typical use-case of this component is on top of images within promos for articles that contains a video asset at the top of the page. It indicates to the user that the link is to a video and how long the video is in duration.
Top story promos can also have related stories links called Index Alsos. When an Index Also item is a video, audio or photogallery, an icon should be displayed with the content using the MediaIndicator component passing the isInline prop.
import MediaIndicator from '@bbc/psammead-media-indicator';
import { latin } from '@bbc/gel-foundations/scripts';
<MediaIndicator type="audio" script={latin} service="news" />;
When using this component ensure you add the relevant spacing.
E.g.
import styled from '@emotion/styled';
import MediaIndicator from '@bbc/psammead-media-indicator';
import { latin } from '@bbc/gel-foundations/scripts';
const TimeDuration = styled.time`
margin: 0 ${GEL_SPACING_HLF};
`;
<MediaIndicator type="audio" script={latin} service="news">
<TimeDuration datetime="PT2M15S">2:15</TimeDuration>
</MediaIndicator>;
When to use this component
The MediaIndicator component is designed to be used on top of an image which is linking to a page containing a video, audio or photo item based on that image. It tells the user to expect video, audio or photographic content on the page as well as how long it is in duration if applicable.
Also, it is used in Top story promos within Index Alsos media links.
Accessibility notes
This component is marked as aria-hidden="true", which means that it should be ignored by screenreaders. It is expected that media promos provide detailed information about their content such as duration in visually hidden text in the promo headline.
