// WARNING : KNACSS grids are flexbox based and only supported by IE10+
// Tuto : http://www.alsacreations.com/tuto/lire/1659-une-grille-responsive-avec-flexbox-et-LESS.html
// Demo : http://codepen.io/raphaelgoetter/pen/ZYjwEB
// Usage in vanilla CSS:
// - <div class="grid-4"> for an equal fourth columns grid container
// - <div class="grid-2-1"> for an uneven columns grid container
// Usage with preprocessors : if you're using Sass, you can config grids variables :
// n = number of columns (default = 4) / g = gutter value (default = 1em)
// example : .grid-container { @include grid(12, 10px); }
// ... or uneven grids :
// left = left ratio column (default = 2) / right = right ratio column (default = 1) / gutter (default = 1em)
// example : .grid-container { @include uneven-grid(2, 1, 10px); }
// Sass mixins for *equal* columns grid container
// example : .grid-container { @include grid(12, 10px); }
