A grid is a series of intersecting horizontal and vertical lines that serve as guides to place elements in a design. To put it in simple words, grids are a system for creating order among elements in a website.

It helps users to better understand the information as it's shown in a more structured and logical way. In this post we showcase 30 beautiful grid-based websites. Enjoy them!
