Picnic CSS is a CSS library containing pre-styled buttons, form, table, grids and nav created by Francisco Presencia. Picnic CSS is really handy when you are building a new website from scratch and want to speed up your styling time. It works by having most of the basic HTML elements already styled with minimal or no CSS classes. The author affectionately describes this feature as “invasive” for its tendency to mess with other CSS styling you may have. Luckily, in the Sass version there’s a flag that you can set to disable the “invasive” nature of the library.
