Media Queries in Sass

_media-queries.scss

// Media Queries in Sass 3.2
//
// These mixins make media queries a breeze with Sass.
// The media queries from mobile up until desktop all 
// trigger at different points along the way
//
// And important point to remember is that and width
// over the portrait width is considered to be part of the
// landscape width. This allows us to capture widths of devices
// that might not fit the dimensions exactly. This means the break
// points are seamless.

Are you still using this? I just implemented it and love it so far. Just curious if you still use it in your work flow. The only drawback I found is it generates a ton of excess media queries once compiled. But I found a Grunt plugin to combine them so its ok.

Thanks anthonyshort, very helpful little gist.
What do you think of this as an improvement to the API?

To summerise:

• Removed -only suffixes as they are superflous
• Changed -below to -down as down is the opposite to up, therefore makes the naming more intuitive (also reduces length by 1 char, bonus!).

Here is my take on a media query mixin. There's less hardcoding involved and it supports as many screen sizes as you wish because it utilizes maps and functions. It's not that better than this gist, but is DRYer.
