really simple media queries with Sass

 Compass is a CSS authoring framework which uses the Sass stylesheet
 language to make writing stylesheets powerful and easy.
 .
 Breakpoint makes writing media queries in Sass super simple. Create a
 variable using a simplified syntax based on most commonly used media
 queries, then call it using the `breakpoint` mixin. Breakpoint handles
 all of the heavy lifting, from writing the media query itself, to
 handling cross-browser compatibility issues, so you can focus on what's
 important: making sure your website looks its best.
 .
 Breakpoint also allows you to get the context of your media queries
 from your code, allowing you to write dynamic mixins based on their
 media query context.
 .
 Additionally, Breakpoint includes Respond-To syntax for the semantic
 awesomeness of string names to identify your queries as opposed to
 variables, and for dynamically generating media queries.
