Unsemantic CSS Framework

Unsemantic is a fluid grid system that is the successor to the 960 Grid System. It works in a similar way, but instead of being a set number of columns, it’s entirely based on percentages.

For instance, if you want a 50% wide column, simply use class=”grid-50″. There are grid classes for multiples of five: 5, 10, 15 … 95, 100. There are also grid classes for dividing a page into thirds: grid-33 and grid-66.
