// 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-perso { @include grid(12, 10px); }
// ... or uneven grids :
// left = left ratio column (default = 2) / right = right ratio column (default = 1)
// example : .grid-perso { @include uneven-grid(2, 1, 10px); }
