KNACSS minimalist, responsive and extensible CSS framework

If you don't want a big dependency like boostrap in your web project, but you still do not want to reinvent the wheel, KNACSS is a great start for your
CSS.

Exemple :

.line.mt1 // describe a line with a 10px margin-top
     .mod.w33 // Set a column with 33% width
     .mod.w66 // Set a column with 66% width
