Usage
psammead-caption can be used together with the psammead-figure and psammead-visually-hidden-text components in this way. This visually hidden text is to give context to users of Assistive Technology.
import Caption from '@bbc/psammead-caption';
import Figure from '@bbc/psammead-figure';
import VisuallyHiddenText from '@bbc/psammead-visually-hidden-text';
import { arabic } from '@bbc/gel-foundations/scripts';
const Wrapper = captionText => (
<Figure>
...
<Caption script={arabic} service="news">
<VisuallyHiddenText>Image caption, </VisuallyHiddenText>
{captionText}
</Caption>
</Figure>
);
When to use this component
The Caption component should be used only within a figure element. It is designed to be placed after an image or video component.
Accessibility notes
Since this is just a <figcaption> tag with associated styles, when you use this component, it has the same semantic meaning as a regular figcaption element.
The font and background-color choices meet WCAG AA colour contrast guidelines.
Roadmap
When this caption is used for scripts that do not support italic text, we can consider creating a prop that toggles the font-style: italic.
