Jonathan Snook, Designer, Developer at EverywhereChristopher: It's not really clear what behaviour you're running into. Could you describe what is going wrong? Try just making sure that the orientation javascript is even running by using a console.log or an alert. Once you know that's working, then make sure the CSS is correct by starting with a simple selector like whether .orientleft has a 5px green border and see what happens on orientation. WIth that said, iOS5 had a bug where orientation change would resize the viewport awkwardly. The technique is a little awkward, which the next slide actually tries to demonstrate and should probably be best just to avoid.11 months ago
Danny LeiYeah, it was a great presentation. I was trying to download the slides, but it came down as an 18MB .key file. Is the file corrupted or just the wrong file extension? I tried forcing it to pdf, ppt, doc to no avail. Any help will be appreciated.2 years ago

Performance Use CSS instead of JavaScript for Animations use CSS Transitions use CSS Animations use 2D and 3D transforms to force hardware acceleration
Hardware Acceleration 2D and 3D transforms may be hardware accelerated use translateX/Y instead of top/left use rotateX(0) to push items with heavy CSS to use hardware acceleration (it’s like IE’s zoom:1 to force hasLayout)
Wait, what about Android and webOS?

Going Native
Why Native over Web? Access to native hardware and other applications Camera, Address Book, Filesystem Streamlined Revenue Process
Meet in the middle Many apps take advantage of native WebView to load application components from remote server allows for iteration of some app components without requiring complete approval process from app store
