The Responsive Grid System isn’t a framework, it’s a quick, easy & flexible way to create a responsive website. With it, you won’t be forced into having a fixed number of columns across a whole page. You can have whatever you want, wherever you need them. Because it uses percentages, your fluid columns will fit any width. The margins (gutters) use percentages too. Also, instead of fitting your content to your grid, you can make your grid suit your content: it plugs into your existing HTML and CSS, and it’s so easy to do so and you can use it on as simple or as complex a project as you wish, allowing you to be done in minutes.
