features you can use today
Theresa O’Connor @ Ignite San Diego
When will HTML 5 be ready?
LC in October 2009
CR in 2012, REC in 2022
Browsers
Charging ahead to implement this stuff
(Re)introduced features
Lots of features with years of wide brower support that aren’t in HTML 4.01 or related specs
JavaScript APIs
HTML 5 is not just elements and attributes
Specified in terms of the real DOM in actual browsers
Progressive enhancement
is the new
graceful degradation
The doctype
<!DOCTYPE html>
Triggers standards mode in all major browsers
Offline webapps
<html manifest="example.manifest">
New sectioning elements
<article>,
<section>,
<header> &
<footer>,
<nav>,
<aside>, and
<hgroup>.
Work in IE with html5shiv, and
older Firefoxen by simply styling them display:
block
Block-level links
<a href="http://example.org/">
<h1>Example</h1>
<p>Something here.</p>
</a>
No, this doesn’t work with <tr>.
<canvas>
Works in IE with Google’s excanvas shim.
contenteditable=""
This slide itself is editable!
XMLHttpRequest
The engine of AJAX
innerHTML, document.write()
And other bits of DOM 0 that haven’t been specced before

Safari & FF have native support
IE & Chrome with Gears
