LostGrid
LostGrid is a powerful grid system built in PostCSS
...Thus, LostGrid is limited to browsers that support calc(). The great thing is that calc() is widely supported in all current browsers and the LostGrid usage of calc() is supported as far back as IE9+. If using LostGrid in flexbox mode browser support is limited to IE 10+. To create a basic horizontal grid, just insert some elements into any containing element like so and pass a fraction to the `lost-column` property. To unset (or remove) a column rule, possibly at a larger breakpoint, use `lost-column: none;`
