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.

We are still designing for screen sizes, it's just using semantics that are easier for people to understand. 'phone' is extra small, 'tablet' is small, 'desktop' is medium and so forth. If we're basically aiming for those devices we might as well use names we can remember :)

But there's definitely some parts that I'll borrow from yours. Might want to check and see if that compiles though. I know in the current version of sass you can't do variables in media queries. That might be fixed up now though.

You'r right.
Maybe semantics name are not bad after all. I will add verbose mixins with name like this.
You can use variable in media queries with the latest sass 3.2 available.

Bit more research to do with common device widths: http://www.metaltoad.com/blog/simple-device-diagram-responsive-design-planning

Specifically, this image - http://www.metaltoad.com/sites/default/files/Responsive-Widths_0.png

Judging from this I'd say it would be best to use the points:

• 320
• 600
• 800
• 1024
• 1280

I'll need to do some more testing though.

Really interesting source.I like the "6 layouts". Maybe I will do something fluid enough to be able to use 3, 4 or 6 layouts as you wish. Hard to code maybe.

Having a few issues on my end trying to implement this concept.
To start I am running Sass 3.2.0alpha.94 bleeding edge

I started by copying the gist above and saving it to my project as _media-queries.scss

When I simply @import "media-queries" into my working scss file I get the following error:
Syntax error: Invalid CSS after "................*/": expected selector or at-rule, was ......

It seems to get stuck at the initial import rule. Is there a different vs. of Sass or something that I should be using to solve this error?

@anointed I'm fairly sure you'll need a more recent version of the Sass alpha

thnx, all sorted now

are you updating it right now ?

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.

@anthonyshort what is this licensed under?
