Building Better UI Designs With Layout Grids

Designers of all types constantly face issues with the structure of their designs. One of the easiest ways to control the structure of a layout and to achieve a consistent and organized design is to apply a grid system.
A grid is like invisible glue that holds a design together. Even when elements are physically separated from each other, something invisible connects them together.
While grids and layout systems are a part of the heritage of design, they’re still relevant in this multiscreen world we live in.
