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 masonry grid. That means every image is downsized to the same width, but the original aspect ration is retained — some landscape, some portrait. This creates an uneven, brick-like appearance of even columns but uneven rows, popularized by the social media site Pinterest. You can control the number (and therefore width) of columns and many other aspects of your ProPhoto Grids. The other grid format is cropped, which produces a uniform matrix appearance with even rows and columns, by cropping each image to the same custom ratio.
Grids also can have one of two “styles.” This grid is in the “Text below” style, where the title and text for the grid is always visible below the grid item image. This style is extremely customizeable through the ProPhoto customization admin screen. The other grid style is “Text overlaid”, where the text appears in a semi-transparent overlay on top of the image when the user hovers over the grid item.
