The 3 C’s of the Mobile Web• Cost

If you don't develop your mobile website responsibly, the user could get stuck with a big bill in order to view your content.

• ContentIssues like navigation, image sizes, page weight and scripts all need to be considered when thinking about your website on mobile devices.

• ContextWhat does your website add to the users mobility? How do you add value to the their physical context? What is the context in which they will use your site? On a bus or train?

Jargon Alert

ContextThe circumstances that form the setting for an event, statement, or idea, and in terms of which it can be fully understood and assessed.Considered together with the surroundings or circumstances.

Designing for Context• Address the inherent benefits of the media.

Conditional CSS

Using Media Queries• Calling an iPhone stylesheet:

• To specify a stylesheet for everything else:

• To specify a stylesheet for everything else:<link media="screen and (min-device-width: 481px)" href="other.css" type="text/css" rel="stylesheet">

• Do not use:

• Do not use:<link media="handheld" href="mobile.css" type="text/css" rel="stylesheet">

Simple Device Detection

Device Detection• Use a simple Javascript redirect WebKit

browsers:<script type="text/javascript" charset="utf-8">

if (navigator.userAgent.match(/AppleWebKit/i) && navigator.userAgent.match(/Mobile/i)) { window.location.replace('/path/to/site/'); }</script>

• Or you can use other methods of Device Detection:

Server RedirectsWURFL (http://wurfl.sourceforge.net/)

PHP (http://www.andymoore.info/php-to-detect-mobile-phones/)

URLs (e.g. m.domain.co.uk, domain.co.uk/m, domain.mobi)
