This style automatically creates a grid layout for the gallery. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall. It does so regardless of their sizes and aspect ratios. The system will allot 20% of the avilable width to each column of images.
Once you click an image, it opens in a lightbox, where you can then move forwards/backwards to navigate. The gallery can open in autoplay mode if you want.
