 ## Why Nth-Grid?
 
-Nth-Grid provides all of the features expected of a modern CSS grid system while simplifying grid concepts and implementation.
+Nth-Grid was conceived long ago (2011) when CSS grid-based layouts were gaining popularity, responsive design was still a new but exciting concept, and support for "legacy" browsers was required for most websites and applications. Specifications for modern layout modules like [CSS Flexbox](https://www.w3.org/TR/css-flexbox-1/) and [CSS Grid](https://www.w3.org/TR/css-grid-1/) were years away from being finalized and widely support, so [float](https://developer.mozilla.org/en-US/docs/Web/CSS/float)-based layouts were the preferred method of implementing CSS grids. Frameworks like [Bootstrap](https://getbootstrap.com) and [Foundation](https://get.foundation) were quickly establishing themselves as the "easy" way to implement grid-based layouts, but their systems were inflexible and required scattering arcane CSS class names throughout a project's HTML. Stand-alone libraries like [Semantic.GS](https://dbwebb-se.github.io/semantic.gs/webroot/) and [Susy](https://www.oddbird.net/susy/) provided grid flexibility, but they worked with only one CSS preprocessor and required scattering grid helpers throughout a project's CSS.
