A grid system for fixed and fluid layouts
Responsive Make the grid fluid or fixed and add per-media layouts as needed. Change the column and gutter widths and remove or add columns as needed. Semantic The grid keeps your markup semantic and works without any "grid_x" classes. Unless you want to use them, in which case they are included. Precise Profound Grid uses negative margins to calculate columns. Unlike with other grid systems, fluid layouts will look exactly the same in every browser.
