Fluid grid

Setting a fluid grid is kinda tricky.
Responsive design is based on break-points, these are specific values (widths are the most common) that define a set of css rules to be applied inside a certain range of browser widths.
Actually, all of sasson grids start as fixed width and under a certain width become fluid to always fill the smaller browsers, this happens right after the first break-point.
To get a fluid grid, all you have to do is insert a very high value in the first break-point (e.g. 2000px), this means that all browsers (desktop with large screen too) will get a fluid grid.
