Six Questions: Eric Meyer on CSS3
Eric A. Meyer knows a thing or two about standards-based CSS and HTML development. He’s a distinguished expert on CSS and HTML, an author of numerous books on CSS, co-founder of An Event Apart, a coveted guest speaker, a member of the A List Apart crew, and founder of Complex Spiral Consulting (I could go on – but I think you get the picture).
Eric Meyer was also a prominent invited expert for seven years in the CSS Working Group, the folks in charge of maintaining and developing CSS.
Needless to say, he’s a person you’d want to ask about the CSS3.
Today I ask Eric Meyer six questions on the topic of CSS3, and here’s what he has to say.
What do you think are the most exciting developments and extensions of CSS in CSS3?
[Eric Meyer]: This will confirm once and for all that I’m basically a big huge code nerd, but honestly, the advanced selectors. Sure, sure, opacity and rounded corners and multiple background images and pretty things blah blah blah. All very nice. But the power to describe Web 2.0 designs in CSS is insignificant compared with the power to select every third table row starting with the fifth one. Or being able to select the first paragraph within another element, even if it’s not the first child. Or selecting any list item that’s the last item in the list. Oh yeah, that’s the stuff.
Well, and Web Fonts are kind of cool too. I’ll grant you that.
Let’s discuss the modularization of CSS specifications. The CSS specification for CSS3 is modularized (presumably after lessons learned in CSS2) – how has this affected the timeline, progression, and mainstream adoption of CSS3 specs?
[Eric Meyer]: It really means there is no such thing as "CSS3" the way there was a CSS2. There’s no great big monolithic specification called CSS3. There’s just a bunch of parallel efforts, some of which move more quickly than others.
I don’t honestly know what it’s done to adoption. We had a great big long pause in CSS advancement in the first half of this decade– I call it "the IEnterregnum"– and it’s only been recently that we’ve seen browsers pushing past the edges of CSS2 in any major way.
On the other hand, you could argue that the pause was good because it let vendors focus on fixing bugs and reaching consistency instead of running off in ten different directions. Nor would I oppose that argument. My real point is that because of how things have gone, it’s hard to measure CSS3 adoption against what came before.
I do think the split caused an overall slowdown in the development of the specifications. No way to prove that, of course, but that’s the feeling I get. It’s a big part of why I left the WG, and why I’ve been only peripherally involved in some of the other W3C’s efforts.
For example, under the proposed specs, you’ll be able to select the first element of
[Eric Meyer]: From what I’ve seen, most of the influence has been on JS frameworks like jQuery, with that influence coming from CSS. However, there is some movement going back the other way– ideas like ‘
:contains‘ that were first done in JS are starting to be considered by the CSS WG.
I think the much bigger influence on CSS by JS will be in people using JS to "silently" add advanced CSS to browsers. I wrote about this recently, and I’m pretty sure it’s just a matter of time before it actually happens. We’re already seeing things like using JS to natively turn browsers into speaking browsers, and to hack around ancient accessibility barriers. Adding support for HTML5 elements and CSS3 features via JS is not far behind.
What resources should we check out if we want to learn more about CSS3?
[Eric Meyer]: http://css3.info/ is a good start. There aren’t a ton of resources out there beyond that, I think mostly because so little of CSS3 is widely supported.
CSS is getting bigger and more complex, Do you think the status of CSS3 should be versioned every time major modules are completed (i.e. CSS3.1, CSS3.2), unlike CSS1 and CSS2?
[Eric Meyer]: Yes, I think that would be a good idea. I just don’t expect it to happen because it’s not very practical. You’d have to only capture those modules that are stable, and the odds of more than three modules being stable (as opposed to stagnant and abandoned) at any one time are pretty low.
What can we (as developers and designers) do to help with CSS3 development and mainstream adoption?
[Eric Meyer]: Write blog posts and tweets and forum posts about what you want to use now, but can’t. Find ways to simulate what you want and write about that.
Submit feature requests to browser teams. File bugs you find on existing CSS3 features (like advanced selectors).
All that stuff is how we vote in our field, to the extent that we have a vote.
