This is an example of a ProPhoto Grid. This particular grid is a “Recent Posts” grid — which dynamically displays a fixed number of your most recent blog posts. In ProPhoto you can also create several other types of grids including: selected posts/pages, popular posts, recent posts from a single categories, alll blog post categories, galleries, and custom items. You can also use grids to display your post excerpts.
Grids can be displayed in two formats: cropped or masonry. This grid is a cropped grid. That means that every image is cropped to the same ratio, creating a uniform, grid-like appearance with even rows and columns. You can control the size of the grid items, and the crop ratio. The other grid format is masonry, which allows for an uneven, Pinterest-style appearance.
Grids also can have one of two “styles.” This grid is in the “Text overlaid” style, where the text appears in a semi-transparent overlay on top of the image when the user hovers over the grid item. This appearance of the overlay is extremely customizeable through the ProPhoto customization admin screen. The other grid style is “Text below”, where the text portion of the grid item is always visible below the grid item image.
