"The primary design principle underlying the Web's usefulness and growth is universality.

The Web should be usable by people with disabilities.It must work with any form of information, be it a document or a point of data, and information of any quality–from a silly tweet to a scholarly paper.

And it should be accessible from any kind of hardware than can connect to the internet: stationary or mobile, small screen or large."

clouds are hip these days...

for it's profile cookie...server then asks the client

server

...profile please?

http://domain.org

yeah, you're going to need a profile...

cookie the server creates one for it...if a client doesn't have a profile

http://domain.orgserver

let's start with the 'default' profile...

that covers the very basic experience...begin with a baseline profile

or default*


default profile

{ width:{ screen:240, document:240 }}

*defining a 'default' baseline profile depends on your project requirements...

notice that this makes the assumption that basic = default (in other words "mobile first")

...oh yes, user-agent please?


(trust me, it's more useful than you think)then...grab the client user agent string

Mozilla/5.0 (Linux; U; Android 2.1-‐update1; en-‐gb; Nexus One Build/ERE27) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17

eww....

hey DeviceAtlas, wanna check this UA for me?



a device database such as DeviceAtlas...query the user agent string against

...or WURFL


DeviceAtlas profile

{ width:480, height:480, color-‐depth:8, touch:true, cookie:true, ...}

http://deviceatlas.com

...found it, here it comes!

any tacit knowledge you have collected...now query the user agent string against

http://diveintomark.org/archives/2009/11/02/why-do-we-have-an-img-element

was an after thought

the <img> tag...



<image alt="butterfly"><source src="butterfly-‐small.png" width="100" height="80" /><source src="butterfly.png" width="200" height="160" /><source src="butterfly-‐large.svg" width="400" height="400" media="min-‐device-‐width:320px" />

</image>

to rethink it?

...perhaps it's finally time

this of course does not exist, and is simply wishful thinking...

<html>...

@media all (max-‐device-‐width:320px) { <img src="butterfly-‐small.png" width="100" height="80" />}

@media all (min-‐device-‐width:320px) { <img src="butterfly.png" width="200" height="160" />}

@media all (min-‐device-‐width:320px) and (svg:true) { <img src="butterfly.svg" width="400" height="400" />}

...</html>

ie: conditional content

...media queries for the DOM?

this of course does not exist, and is only the simplest form of an idea...
