So what is it?

Flexboxgrid is a CSS grid system built on the flexbox layout model, a CSS feature that controls how elements are arranged and sized within a container. Grid systems give web developers a structured way to divide a page into rows and columns, with content that adjusts at different screen widths. Instead of writing custom layout rules from scratch every time, developers add pre-defined CSS classes to their HTML elements and get consistent, column-based layouts right away. Flexbox, which this library is built on, handles spacing and alignment more predictably than older layout methods like floats. Flexboxgrid packages that technology into a simple, class-based grid, similar in approach to the grid found in widely-used CSS frameworks. The library is a single stylesheet with no JavaScript or other dependencies. It can be added to a project through npm, Bower, or a CDN link, or by downloading the CSS file directly and linking it in an HTML page. Both a development version and a minified production version are provided. The README is brief and focused on installation options. Further documentation and a live demo of the grid system are available on the project's website at flexboxgrid.com. The repository also lists several open-source grid experiments that served as inspiration during development.
