Replicating and improving the lightbox module seen on Medium with fluid transitions.As Fluidbox relies on CSS transforms, it only works with thumbnails that share the same aspect ratio with their higher resolution counterparts, otherwise the larger image will be cropped off, i.e. a square thumbnail linking to a landscape photo will cause the landscape photo to appear in a square frame. Fluidbox, serving as an alternative lightbox module, also assume that the image you have linked contains sufficient resolution to be displayed on the monitor — low resolution images will scale poorly on a large display.
