Box

Box is different from other CSS frameworks because it relies on the 'box-sizing: border-box' and 'display:inline-block' properties for creating its layout.

This allows it to work with both pixel and percentage-based layouts, being extremely easy to customize, with changeable gutter and margin settings.

Box was tested in most major browsers and found to be working even in older IEs (8+).

The framework can be used for both mobile and desktop projects, and also comes with a few demos packed in the download files.
