ungrid, believe it or not is under 100 characters. And yes, you read that right, characters, not lines of code.

This ultra-lightweight grid system uses a table-based display setting to automatically support responsive layouts, just like all native HTML tables tend to automatically work with responsive layouts.

You can use it in a very simple way, just by adding the "row" and "column" CSS classes to your HTML code.

This lets developers roll out responsive grids in a matter of seconds and provide a mobile-friendly layout for their Web projects.
