One aspect of a "mobile first" approach to development is that your styles are usually gradually built up from a simple base. Each new "layer" of CSS adds presentational adjustments and complexity, via CSS3 Media Queries, to react to and make use of additional viewport space. However, IE 6/7/8 do not support CSS3 Media Queries. If you want to serve IE 6/7/8 something more than just the base CSS, then you need a solution that exposes the "enhancing" CSS to those browsers.


Det här känns vettigt och pragmatiskt. "Mobile First" är ett koncept jag tror på till fullo och det känns tryggt att det händer saker.
