Use style, hoverStyle and activeStyle to craft distinct visuals.
Style any article via timeline-level defaults or per-article options. Hover and active styles inherit from the base style, letting you override only what is needed.
To clear system defaults for active and/or hover styles after initialization, delete individual properties from the style object or reset all by setting to an empty object, for example:
myTimeline.options.article.defaultActiveStyle = {}myTimeline.setOption("article.defaultActiveStyle", myActiveStyle)/* Select an article in the timeline to see its style here *//* Select an article in the timeline to see its hoverStyle here *//* Select an article in the timeline to see its activeStyle here */Toggle the default card layout between landscape and portrait. You can set it at init via options.article.defaultCardLayout or after init with timeline.setOption("article.defaultCardLayout", layout).
