Picnic CSS
by Francisco Presencia Fandos
Picnic CSS is a tiny CSS library that you can use to kickstart your projects. It is highly customizable if you use the SASS and I fine-tuned it for size even more to fit this contest. It will give styles by default, so you can keep your html clean off styling classes; buttons know they are buttons, inputs get nice styles, it includes a responsive and highly performance grid, etc.
