continuous|inline|auto

continuous enables classic zoom where the image gradually zooms in as you click, double-tap, or pinch out in the main view. To get back to the initial view, zoom out or reset the zoom state. The class

inline enables instant zoom, where the zoomed image instantly appears as you hover the main view on desktop or to touch and hold on a touch device. The image automatically reverts to initial state after you move your mouse from the view or release your finger. In inline mode, nested image sets are flattened and displayed as individual thumbnails. The class auto activates inline mode on desktop and continuous mode on touch devices.
