Free Grid Design Template: 960 Grid System
Licensed under GPL and MIT, the 960 Grid System is a free grid design template to streamline web development workflow by providing commonly used dimensions, based on a width of 960 pixels. There are two variants: 12 and 16 columns, which can be used separately or in tandem.
Enclosed in the bundle are printable sketch sheets and template files for Adobe Fireworks and Photoshop, OmniGraffle and Visio. Also included is a lightweight CSS file, which contains the grid dimensions. These styles do not automatically make up a finished site design. They are simply a starting point, ideally for rapid prototyping or as a basis for creating your own designs.
