Many designers use a grid as the foundation for every one of their designs. Some will use a 12-​​column grid, some will use a 16-​​column grid, some will use a 24-​​column grid, and others will use anything in between. The point isn’t so much the type of grid that you use, but the fact that you use one. Grids in web design are very common, and with the implementation of responsive web design, grids have become even more important than ever.
