Jeff is advocating blinking in CSS. Oy. Anything between a 2Hz and 60Hz frequency is *unhealthy* to look at! That's what blinking does! I don't know how I feel about this animation support in Webkit,...

I don't see this idea to be useful at all. It seems like a complete IE6 type of move -- if it's not something that will be supported by everyone (IE, 'fox, Opera), why create it? What value does it...

@Chris: What's wrong with blinking? The bling HTML element was a bad idea, because a presentational property should not be part of HTML, but it would be perfect for CSS. Granted, the property would be...

I am only half an expert compared to most hear but they way I see it is that CSS should stay for STYLING (hint: Cascading Style Sheet) :?

Jonathan, my first impression with this idea was the same as yours. However, the more I think about it, the more appealing I find it. Bear with me for a moment... The common javascript syntax for most...

Michael - Multiple backgrounds are in the CSS3 specification for sure, but to be honest I have no idea why they aren't supported anywhere else yet. Adding more markup to achieve the same effect defeats...

@Johnathan: Why is a CSS solution better than a JavaScript solution?Because it allows visual layer animation to be decoupled from behavioral programming and coupled with visual styles that it belongs...

Ben: Having multple backgrounds is a property of CSS3, not because the WebKit team is particularly clever. I was unaware, though, that the animations being discussed are for smooth transition...

I agree with Dave Hyatt, this type of animation is styling and belongs in CSS. Perhaps there'd be less confusion if we call it "CSS Transition Effects", rather than "CSS Animations". It doesn't do full...

Looking at this from a cross-browser development angle is nonsensical. Surely CSS is meant to enhance a person's experience of a website? Wouldn't you prefer your ice cream with chocolate sauce and a...

This is bad, really bad. I already have enough trouble trying to get effects with Javascript working cross browser wise, and this can add some more confusion, frustration, headaches, and broken...

this sounds like Safari heading to Microsofts IE proprietary filters ... CSS is to give style to content not to animate content.

I'm with Anton on this one. Presentational animation in CSS seems logical, but you really want control. You want event triggering and you want better control over the conditions of those animations...

Jonathan: I totally agree with you that a JavaScript solution is probably better, as in it's probably more flexible, more robust, and more useful (after all, JavaScript is a full programming language,...

I agree. This is far too familiar, like Microsoft's proprietary extensions to DOM, their half-assed CSS implementations, as well as proprietary CSS (filters that use DirectShow and those awesome page...

I'll probably just use Flash instead... neither CSS nor JS. ;-) Seriously though for a moment, for all the good points on both sides, I'm trying to think of a real-world situation where I will need an...

Why is a CSS solution better than a JavaScript solution? How it addresses the technical issues (when did the animation start, what is the value at any given time, what happens when I try to access a...

It's border-line, but I tend to agree with Dave/Jeff. In my opinion, behavior means user-interaction. There can be two types of animation: animations that are part of visual presentation and animations...

Jonathan: thanks for the response. I can certainly see your angle here, but I sympathize with Apple's reasoning, especially as browser developers. This goes beyond the scope of your article, but I feel...

Jonathan, I know you're not anti browser-animation. Still, CSS just makes sense to me as the place for this. Animation is a purely visual and presentational thing. CSS is the best place for visual and...

You can animate from the DOM too, by using CSS object model to set the appropriate style rules. The way it is implemented, it work both ways.

@Dave/Jeff: I define behaviour (of the Content-Presentation-Behavior layer) as change. A user enacts a change by interacting with the page via a mouse click, etc. However, these changes can occur...

Wow, some really good points there. As for accessibility features, I guess browsers supporting CSS animation will have an option to disable it, something like disabling GIF animation. And I never knew...

I agree that animation in general does not need to be in CSS, but I think most are missing where I think this might be used the most - :hover We already use :hover to change the colors of links, what...

I'm with Dave here. The "behavior" in Behavior Layer refers to the behavior of the user. The Behavior Layer might be more aptly-named the user-interaction layer. Animations are presentational. The are...

Yeah I'm gonna have to agree on this one, I can not see anything good coming from this.

I disagree. Many kinds of animated transitions are presentational and have nothing to do with behavior. For example, the pulsing default buttons in dialogs in OS X, or the animated fade that occurs...

I'm all for browser-native animation. Don't really care how to get there, as long as we get it. That said, I agree it'd make more sense to run this through the DOM.

mm, well the only positive thing I can think of is that animations will work for people that have css on but javascript disabled... Otherwise seems a weird thing to do.
