Hello,

Is there anybody who would still want something else than the @region syntax? I see that Christophe sent a clarification about what his proposal was, but since this was prefixed by a JFTR, it seems that we have consensus on sticking with the @region syntax.

I am fine with sticking with @region even though I have been back and forth on this topic. The reason I was feeling warmer to the pseudo-element syntax is that it opened the use of getComputedSytle(elem, pseudo-class). But we can think about alternate ways of providing access to the used style for the fragment of an element falling into a particular region.

To address Fantasai's original concern, would it make sense to say that the @region rule modifies the specificity of the selectors it contains or would that be heresy?

We're just talking about how an element itself looks in a particular region. In the example above the portion of <h1> that is in a region is still the <h1>, so I think a pseudo-class is far more appropriate.
