##How does it work?

Important: Whenever you use screen mixins (min-screen, max-screen, screen, etc) you must use units!

Example 1

min-screen(min-width) - demo

It's a shortcut for @media screen and (min-width ... ) { ... }. Works great with mobile first philosophy

@include min-screen(320px)  { ... }
@include min-screen(480px)  { ... }
@include min-screen(768px)  { ... }
@include min-screen(1024px) { ... }

It will be compiled to:

@media screen and ( min-width: 320px) )
{
  ...
}
@media screen and ( min-width: 480px )
{
  ...
}
@media screen and ( min-width: 768px )
{
  ...
}
@media screen and ( min-width: 1024px )
{
  ...
}

Example 2

max-screen(max-width) - demo

It's a shortcut for @media screen and (max-width ... ) { ... }.

How to use it properly? You should start from the widest screen resolution and proceed to the narrowest one (styles are inherited from previous conditions).

@include max-screen(1024px) { ... }
@include max-screen(768px)  { ... }
@include max-screen(640px)  { ... }

It will be compiled to:

@media screen and ( max-width: 1024px )
{
  ...
}

@media screen and ( max-width: 768px )
{
  ...
}

@media screen and ( max-width: 640px )
{
  ...
}

Example 3

screen(min-width, max-width) - demo

You can add style rules for ranges. It could be really helpful if you want to target group of devices or just one with particular screen resolution.

@include screen(768px, 1280px) { ... }
@include screen(320px, 640px)  { ... }

It will be compiled to:

@media screen and ( min-width: 768px ) and ( max-width: 1280px )
{
  ...
}

@media screen and ( min-width: 320px ) and ( max-width: 640px )
{
  ...
}

Example 4

iOS devices - demo

You can easily manage styles for particular iOS devices:

@include ipad { ... }                     // all iPads
@include ipad-retina { ... }              // only iPad with retina

@include iphone5 { ... }                  // only iPhone 5
@include iphone4 { ... }                  // only iPhone 4/4S
@include iphone3 { ... }                  // only iPhone 2/3G/3GS

Example 5

device orientation - landscape and portrait - demo

Want to add extra stuff only in landscape / portrait mode? Piece of cake:

@include ipad-retina { ... }              // common part only for iPad (3, 4) - landscape & portrait
@include ipad-retina-landscape { ... }
@include ipad-retina-portrait  { ... }

@include iphone5 { ... }                  // common part only for iPhone 5 - landscape & portrait
@include iphone5-landscape { ... }
@include iphone5-portrait  { ... }

@include iphone4 { ... }                  // common part only for iPhone 4/4S - landscape & portrait
@include iphone4-landscape { ... }
@include iphone4-portrait  { ... }

another one:

@include ipad-landscape { ... }           // all iPads - landscape
@include ipad-retina-landscape { ... }    // only iPad (3, 4) - landscape

@include iphone3-landscape { ... }        // only iPhone 2/3G/3GS - landscape
@include iphone4-landscape { ... }        // only iPhone 4/4S - landscape
@include iphone5-landscape { ... }        // only iPhone 5 - landscape

Example 6

hdpi(ratio) - demo

.example
{
  ...

  @include hdpi { ... }                   // only devices with hidpi displays (including retina)
}

or to narrow down:

.example
{
  ...

  @include hdpi(2) { ... }                // only devices with retina
}
