Control it all with JavaScript Guess who doesn't support it? Offline Web Applications Like a cookie (named key/value pairs), but for large amounts of data Websites can store data to retrieve later Currently a separate spec even though still under HTML5 How secure is it and who can read it? Sites define which files the need to work offline (HTML / JS / Images / Video and more!) Email, docs and web apps offline! When online, changes can be uploaded to the remote web server What data is being stored locally? Is it safe to do this? Can use IP, wireless connection, cell tower (phone), or dedicated GPS hardware Find your geographic location from the browser You must grant access for sites to use your location Locating me anywhere?

Form Input Types Form Autofocus No JavaScript Needed
Consistent across all browsers
Good for power users and special needs
Unloaded site does not "help" by refocusing
Browser can offer method to turn this off

Implementations and specifications have to do a delicate dance together. You don’t want implementations to happen before the specification is finished, because people start depending on the details of implementations and that constrains the specification. However, you also don’t want the specification to be finished before there are implementations and author experience with those implementations, because you need the feedback. There is unavoidable tension here, but we just have to muddle on through.

- Robert O'Callahan http://ishtml5ready.com/ http://ishtml5readyyet.com/ http://www.miketaylr.com/code/input-type-attr.html How does your browser form support stack up? + + @font-face {
font-family: Delicious;
src: url('Delicious-Roman.otf');
} Custom Fonts So we're all good, right? Not really - IE does not play well with others

IE needs an .eot font ...
everyone else takes a .ttf or .otf font See the Paul Irish Solution http://paulirish.com/2009/
