I’d like to introduce the “520 Grid System,” an HTML/CSS framework that’s useful for creating Facebook apps (Tab Apps).

The 520 Grid System has a “page width set to 520px” and also supports grid design, making it quite user-friendly and highly recommended!

There also seems to be a framework called “760-grid-system” for Canvas apps.

The 760-grid-system appears to be a mashup of the famous “960 Grid System” framework, and it looks like it would be useful when creating Canvas apps.

That’s all from the Gemba.
