Thanks to everyone that attended my session at the South Florida Code Camp! Massive flat screen TVs, desktop, mobile phones, tablets, netbooks, mini-tablets... Server side device detection is not the only approach available when it comes to servicing the myriad of screen sizes your users could be on. We’ll take a look at responsive web design and the core concepts of making a UI responsive, what tools and frameworks are available now and how best to integrate this approach for your website.

4. A new world…

5. Our agenda…
• Scenario: Getting Started with a mobile
project
• Scenario: Mobile sub sites
• Scenario: jQuery mobile
• Scenario: Responsive design
• Scenario: Application stores

6. Scenario
GETTING STARTED WITH A MOBILE
PROJECT

7. Starter questions…
• What’s your current
mobile statistics?
• What’s your timeline and
budget?
• Who is your target
audience?
• Is there a target platform?
• What are the application
features and
functionality?
• What are the developer
skills?

11. Getting started…
• Depending on your browser you
have a couple of options that you
can use.
– For Firefox you can use the Firesizer
utility available at
https://addons.mozilla.org/en-
US/firefox/addon/firesizer/?src=ss.
– For Internet Explorer you can use the
Internet Explorer Developer Toolbar
available
http://www.microsoft.com/en-
us/download/details.aspx?id=18359
– For Safari you can use the Resize
Safari extension available at
http://www.resizesafari.com/

12. Other places…
• Responsive Design Bookmarklet
– http://responsive.victorcoulon.fr/
• Studio Press by Copyblogger
– http://www.studiopress.com/responsive/
These are just a few places… Any others?

13. Generic mobile requirements checklist…
• Is it readable?
– Consider how easy it is to read text in
columns at various widths and page
sizes.
• Is it visible?
– Make sure all the key information is
above the fold to prevent scrolling.
– Strike the proper balance between
number of display items and detail
level.
• Is it usable?
– Consider the page look when the
page elements are at the proper size
and location for a screen size.

14. Google Chrome playing with user agents…
• Select F12 /CTRL-Shift J
• Select Settings
• Select User Agent

15. Scenario
MOBILE SUB SITES

16. Content redirection to the rescue…
“Device Detection Data is the missing ingredient that can turn any standard web site into
a tailor-made experience for mobile phones and devices. It lets any organisation deliver
an online customer experience with optimised browsing, easier transactions and faster
page loading.”

JQUERY MOBILE

18. Worth a look…

19. Scenario
RESPONSIVE DESIGN

20. Responsive design ISN’T…
• A single technology
• A magic formula
• A quick fix
• Easy
Can you say planning!

21. Responsive design IS…
• Components
– Fluid layouts
– Fluid images
– Media queries
• Google recommends responsive
design for better SEO!
Examples
• http://www.ecentricarts.com/
• http://www.newbornfree.com/home
• http://www.microsoft.com

22. Fluid layouts/images…
• Death to the pixel!
The new math…
Target/Context = result
• Use percentages and em to ensure correct scaling
div{
Width:80%
}
img{
max-width: 100%
}

23. CSS Media queries…
• Ability to target media (devices) with specific CSS
• Target screen sizes with max-width
@media screen and (max-width: 600px) {
.class {
background: #444;
}
}
• Advanced queries with ranges
@media screen and (min-width: 600px) and (max-width: 900px) {
.class {
background: #444;
}
}
• Target device orientation
@media screen and (orientation:portrait) {
}

31. Scenario
APPLICATION STORES

32. What’s the market…

33. What are they?
• Stored and run locally on the device and have
full access to the platform and hardware
Native • Obtained from application stored that includes
a lead time and approval process before
Application deployment
• Developed on the default language of their
respective platform
• Largely based on web technologies running
within a native application mimicking the look
Hybrid and feel of a native app.
• Leverage the device feature to run a web
Application application locally

34. Native apps…
• Performance intensive applications
• Disconnected or offline apps
• Games or apps with rich visuals
Best for • Applications requiring heavy interaction with local data or hardware APIs (camera, GPS,
etc)
• Applications ruining in the background or requiring background processes
• Applications targeting a single platform
• Absolute best performance and rich UX experience, no visual lag or slowness
• Full access to the hardware, capabilities and API’s
Advantages • Marketing boost from app store distribution
• Applications that can be tailored to take advantage of platform specific UI paradigm
• Most mature, well documented and vendor supported development options
• Has to be re-written for each mobile platform
• App store approval mandatory
• Native application development skills harder to find than web development skills
Disadvantages • Platform vendors take a cut of purchase
• Generally the most expensive option
• Deployment and updates are slower, more difficult

35. Hybrid applications…
• Applications with basic user interface and functionality
• Business applications
• Content applications
Best for • Wrappers around mobile and web applications
• Applications targeting multiple platforms
• Applications that won’t be judged on UI speed/performance
• Write once, run anywhere – application doesn’t need to be rewritten for each platform
• Web development skills easier to find than native development skills
Advantages • Able to access most hardware and capabilities and APIs
• Applications still distribute via App stores
• Web based app content can be updated more easily
• UI is lowest common denominator between platforms
• Write once – debug everywhere – still need to spend time ironing out platform issues
• Performance varies between mobile platforms
Disadvantages • Applications store approval still mandatory
• Platform vendor still takes a cut of revenue
• Deployment and upates of the applications (via app store) is still slow and difficult

36. Short list recommendations…
Native applications
• Performance intensive applications
• Marquee applications that can’t compromise on user experience or performance
• Applications for offline or disconnected requirements
• Games or applications with rich visuals
• Applications that require background processing
• Applications requiring heavy interaction with local data or device hardware
• Where cost savings and cross platform code sharing is not a goal
• Where a single device or platform is targeted
Hybrid applications
• Work well for business and content applications with a basic user interface and
functionality requirements
• Targeting multiple platforms
• Adding native functionality to existing web applications or creating a native
wrapper around a mobile web site
• Work well for creating a simple mobile optimized version of an existing site
