Bourbon Neat

Bourbon Neat is a responsive framework that was built to push clean semantic markup.  It’s a Sass @mixin based framework so don’t expect it to work straight from the download.  It’s even got the lovely box-sizing(border-box).

Sassy!

Using Sass 3.2 block mixins, Neat makes it extremely easy to build responsive layouts. Go ahead and resize your browser, we’ll wait.Using the
breakpoint()
mixin, you can change the number of columns in the grid for each media query and even store these values in project-wide variables to DRY up your code.
