Good markup is healthy markup.

Add all the whiz, bang, and fireworks without having

to rely on 3rd party libraries and plugins.

Stuff that took images and extra markup and hours to perfect, now available through a CSS property or two.

APIs that help us build more powerful, feature-rich mobile webapps.

Helping bridge the gap between native and web.

•It's finally growing up

•WebApps are better, smarter, sexier

•WebApps can do more with less

•WebApps can do the same, if not more than Native Apps

Player is customizable and programmatically

accessible through javascript (i.e. play, pause, etc.)

Not the case on mobile devices(iPad excluded)

Most devices offload audio and video playback to

their native media players...which is

a good thing

Oh, and support kinda sucks...

Feelin’ Out of Place, Mr. Box?

#Box1 { transform: translate(10px, 10px);}

CSS animations are smoother, faster, and require far less code.

And just for kicks, we’ll throw in some hardware acceleration

too.

transition: 1s;

Whenever a property for the transition-ready element changes, the browser

auto-tweens the element for you!

#container { transition: 1s;}

#container:hover { opacity: 0.4}

Transition Properties

Which properties should be animated?transition-property: color;

default: all

How long should the transition take?transition-duration: 1s;

default: 0, which means no animation. Required!

Should we wait a bit before starting?transition-delay: 0.5s;

default: 0Can be negative. Will start as if pre-animated.

Transition Properties (cont’d)

Which timing curve should we use?transition-timing-function: ease-out;

default: ease

Other values:

linearease-in

ease-outease-in-out

cubic-bezier (custom-defined)

CO

DE

Feeling lazy? Shorthand it.

p { transition: color 1s ease-in 2s;}

Might change to:

p { transition: color 1s/2s ease-in;}

Want to make everything transition-ready?

(though, probably a bad idea)

* { transition: 1s;}

Whenever possible, use classes instead of direct CSS

manipulation.Generally yields better performance.

What about complex animations?

Combine multiple transitions!

Define tween checkpoints and the properties to be changed at each.

#box1.animated { animation-name: goCrazy }

@keyframes goCrazy { 0% { } 33% { left: 200px; } 66% { -webkit-transform: rotate(-90deg); } 100% { -webkit-transform: scale(2); opacity: 0; }}

Animation Properties

Same as beforeanimation-duration: 1s;animation-delay: 0.5s;

animation-timing-function: ease-out;

Which direction should animations run?animation-direction: alternate;

default: normal;

Which direction should animations run?animation-iteration-count: 4;

default: 1;Use infinite for a never-ending loop.

A blank slate with which you can do (almost) anything:

- create elements, shapes, lines, images, 3D things, text.- modify them- animate them- etc.

function success( position ) {alert( 'Latitude: ' + position.coords.latitude );alert( 'Longitude: ' + position.coords.longitude );// position exposes other properties as well:// timestamp, accuracy, heading, altitude, etc.

function error( error ) {alert( 'Sorry, we could\’nt figure out your location!' );console.error( 'Error', error.code, error.message );// error codes:// 1: location permission denied// 2: location fetch failed// 3: timeout// 0: unknown

IP location can suck.
