Opera 12 beta includes a partial implementation of the spec, which you can try out using Håkon's examples.
The CSS Generated Content for Paged Media Module is a spec spearheaded by our CTO Håkon Wium Lie, and it allows you to create a page-like browsing experience on web pages by adding a few lines of CSS to your content. Furthermore, step-start, step-end and steps timing functions for transition-timing-function are supported as well. We've also expanded our support for animatable properties (so you can animate them using CSS3 transitions as well as CSS3 animations) to include background-position, border-bottom-color, border-color, border-left-color, border-right-color, border-top-color, and text-shadow. Opera 12 beta supports CSS3 animations, and we have prepared a fitting Dev.Opera article to celebrate that.

This morning, we've released Opera 12 beta and as always, a new release comes with improved standards support and other developer features - a quick overview of the shiny: Hardware acceleration and WebGL supportĪs announced last week, we're aiming to make Opera entirely hardware accelerated, from the UI to all page rendering and painting (with support for OpenGL as well as DirectX backends), but for now, both HWA and WebGL are turned off by default.
