Hi handsome.

@media mood and (min-level: fine)

Fine.

@media screen and (min-width: 600px)

Yes.

@media all and (orientation: landscape)

What are you,an idiot?

As you wish.

MEDIA QUERIES

@media [not|only] type [and] (expr) { rules;}

== Feature detection

MEDIA TYPES@media screen { ... }@media print { ... }

@media handheld { ... }



Let’s add some logic...@media screen and { ... }




and a feature to query@media screen and (color) { ... }




and a feature to query@media screen and (color) { ... }

Hey— tell them some more about logic,

you bastard.

logical AND

@media screen and (min-width: 600px) and (max-width: 1200px)

constrains a query

logical OR

@media screen and (min-resolution: 300dpi), screen and (-webkit-min-device-pixel-ratio: 2)

the comma is an OR

logical NOT

@media not screen and (color)

logical NOT

@media not screen and (color)

be careful...

logical NOT @media not screen and (min-width: 600px)


does not evaluate as:@media (not screen) and (min-width: 600px)


does evaluate as: @media (not (screen and (min-width: 600px)))

does not evaluate as:@media (not screen) and (min-width: 600px)

ONLY

@media only all and (device-aspect-ratio: 16/9)

hides the CSS from older browsers

Prefixed Features

Prefixed Features

A pixel is not a pixel.

Prefixed Features

-moz-touch-enabled

Is this a touch device?

@media screen and (-moz-touch-enabled) { /* touchy styles */}

Viewport@media screen and (max-device-width: 320px)


device-width

layout viewport


Meta viewport.

Meta viewport<meta name="viewport"

content="width=device-width">

Meta viewport<meta name="viewport"

content="width=device-width">

@media screen and (max-width: 320px) { div { width: 80%; }}

use that in combination with WIDTH

Meta viewport

@media screen and (max-width: 320px) { div { width: 80%; }}

use that in combination with WIDTH

<meta name="viewport" content="width=device-width,

initial-scale=1">

viewport in CSS?

@viewport { width: device-width; zoom: 1; /* No, not THAT zoom */}

viewport in CSS?

@viewport { width: device-width; zoom: 1; /* No, not THAT zoom */}

Enough already. How can we apply

these things?

Layout is not design.

Design is the art of putting form and content together.

Paul Rand said that

The media query is a screwdriver.

Layout is only one of the components of

design.

Think in terms of design principles & systems

The art of letting go

We need to think up new ways to design layout, and new ways

to communicate these new designs to our colleagues and our clients.
