CSS3 properties invalid.

[Rik]

Hi all,

I'd like to use some CSS3 properties like box-sizing and opacity. It's
poorly supported, I know, but the content will not 'break' if I don't use it
(a nice degrade is always a must).

Now, if I try to validate my pages, W3C nags about them being a
non-existent. Offcourse, I can ignore the validator if I know better, but
I'd like your input on some questions:
1. Is there a way I can 'tell' the UA it's CSS3? (maybe even add a seperate
css for CSS3 properties). Something along the line of <link rel="stylesheet"
href="URI" type="text/css" version="3.0" />
2. Will rendering be 'quircky' if I add properties like this, or will the
page (was is otherwiose fully standards compliant) be rendered the same?

Thanks for your input,

Using the extended interface you can choose to check against another

It will have no effect in browsers.

Damn, why haven't I seen this before?

There is no "version" attribute for the <link> element.

Elas. It was just a suggestion, not an actual code I'd use offcourse.

Good to know. border-box, here we go!

Grtz,
