[css-nav-trans] RFC: Proposal for style rule to specify transitions between page navigations

Hi all,

I've been working on a proposal for a new style rule that will allow page
authors to apply transitions when navigating between pages. I've put it on
github[0][1] for easy perusal and modification.

This was driven mostly by our desire to switch to a multi-page architecture
in the next major version of FirefoxOS, and partly as a reaction to
Google's proposal/demo to do the same thing. I wrote about this in a blog
post[2] (this post is outdated, please see [1] for the most up-to-date
revision of the proposal).

There is intent at Mozilla to implement either this proposal, or something
very similar - I've been discussing this with various interested parties
for a while and would like to formalise it and open it up to wider
discussion now.

I've written up a specification with the aid of bikeshed, and using various
existing specifications (such as CSS transitions, CSS animations and CSS
media queries) as inspiration for language and the amount of detail to
include.

Any feedback and help would be most appreciated, I'm new to this process.

Thanks,

--Chris
