“The web is too important for society to be in the hands of any one vendor”

– Bruce Lawson, Opera

HTML5 is more a collection of new technologies than a single new standard – we can start using parts of it today.

You can use Moderizr to check what HTML5/CSS3 features are available in your browser. You can see it in action at FindMeByIP.

Canvas/SVG

Cross-browser canvas support & speed

Canvas is possible in IE using a single script tag: check out Excanvas

Filament have created accessible charts from HTML tables using the canvas element: jQuery Visualise plugin

Accessibility: canvas or SVG?

• With images off, canvas elements are essentially blank, whereas SVG remains as text
• Use SVG for content and canvas for bling (for now)

Forms

Browser handles special field display and front-end validation that has traditionally required Javascript (popup calendar, focus on field, email validation, required field validation).

Geolocation

Currently iPhone Safari and Firefox 3.5 only.
