What Developers Told Us Interoperability and Same Markup

HTML5 Canvas, Audio, Video, XHTML, SVG, DOM L2 Core, DOM L2 & L3 Events, CSS3 Selectors, DOM Traversal, DOM Range, HTML5 Parsing, etc.

Performance Holistic Focus on Performance, Faster JavaScript, GPU Powered

Graphics

Websites more like native applications Reducing the User Interface surface area, Unlocking the

Hardware

Safe and Trusted Browsing No ActiveX Controls, no Browser Helper Objects, no Plug-ins or

Binary Behaviors

Key IE9 Windows Phone Technologies for Mobile

• Support for Viewport <meta> tag

• Support for W3C Geolocation, including GPS

• Full support for CSS Media Queries

• DOM Local Storage and Session Storage

• Data URIs


Controlling the Viewport

<META name="HandheldFriendly" content="true" />

<META name="MobileOptimized" content="320" />

<META name="Viewport" content="width=device-width" />


Controlling the Viewport

Viewport Property Description

width Sets the width of the viewport. Can be either an integer value or "device-width". Defaults to 1024 on Windows Phone, 980 on iPhone

height Sets the height of the viewport. Can be either an integer value or "device-height".

initial-scale Sets the initial scale value of the viewport. Defaults to 1.0.

maximum-scale Determines the maximum scale value of the viewport. Range is from 0.1 to 10.0

minimum-scale Determines the minimum scale value of the viewport. Range is from 0.1 to 10.0

user-scalable Boolean that determines whether the user can scale the viewport


Using Media Queries Provide a way of applying style sheets based upon certain

characteristics of the media Window size, screen size, aspect ratio, color depth,

resolution, etc. Are a W3C candidate recommendation as of July 2010 Specification can be found at

http://www.w3.org/TR/css3-mediaqueries/ <link rel="stylesheet" media="screen and (max-width:800)" href="example.css" />

@media screen and (max-width:800) { /* style definitions that apply to screens less than 800px wide */ }

Or…

http://www.w3.org/TR/css3-mediaqueries/




Using Media Queries Media Query Feature

Description

width Indicates an output surface, such as a window, of exactly width units (px, etc.)

height Indicates an output surface, such as a window of exactly height units

device-width Indicates a device that has exactly the given width, in given units

device-height Indicates a device that has exactly the given height, in given units

orientation Used with “portrait” or “landscape” for devices that can do both.


Using Media Queries

<link rel=“stylesheet” media=“screen and (min-width:480px) and (max-width:800px)” href=“styles.css”> @media screen and (min-width:480px) and (max-width:800px){ /* style definitions that apply to screens less than 800px wide */ }

<link rel=“stylesheet” media=“screen and (max-device-width:800px)” href=“styles.css”> @media screen and (max-device-width:800px) { /* style definitions that apply to screens less than 800px wide */ }

Geolocation Geolocation allows a phone to figure out where it is

IP Address location or Wireless network location

Triangulation of cellular towers

GPS device that uses satellite signals

Can get location as a "one-shot" or continuously

Location is always opt-in

“User Agents must not send location information to Web sites without the express permission of the user.”

W3C Geolocation API

http://www.w3.org/TR/geolocation-API/





Geolocation

API: getCurrentPosition(successFn, errFn, options) watchPosition(successFn, errFn, options) clearWatch(watchID) successFn( positionObject ) errFn( positionErrorObject )


Client-side LocalStorage / SessionStorage

Provides easier way of storing data on client without cookies


DOM Storage API Available from the window object: window.localStorage

window.sessionStorage

getItem(key) setItem(key, value) removeItem(key) clear() key(index) length
