The amp-lightbox component allows for a “lightbox” or similar experience - where upon user interaction a component expands to fill the viewport, until it is closed again by the user.
The amp-lightbox component defines the child elements that will be displayed in a full-viewport overlay. To close the lightbox via click or tap use the on attribute on one or more elements inside the lightbox. In this example the user can click anywhere in the lightbox to close it.
