[css-view-transitions-2] Consider allowing ::view-transition-group(.class) without *

[noamr]

This would be consistent with how class selectors work outside of view-transitions.

[vmpstr]

Probably to go with #9626 as well

[astearns]

Right. I believe :active-view-transition is meant to cover this case

#9972 (comment)

(if I am incorrect, please re-open this issue)

[vmpstr]

This is a separate issue. #9972 only dealt with :active-view-transition* pseudo classes.

This issue is about allowing ::view-transition-* pseudo elements to also omit the asterisk if a class is specified. Note that I think we would still want to require the asterisk if there is no class or specific name specified, but that can be discussed

The CSS Working Group just discussed [css-view-transitions-2] Consider allowing `::view-transition-group(.class)` without *, and agreed to the following:

• RESOLVED: Make * optional if you are using a class.

The full IRC log of that discussion

<keithamus> vmpstr: we have VT pseudo elements. They take a name param, or universal selector *. We also added vt classes that specify a name and set of classes that are written as .foo.bar.
<fantasai> +1 to allowing the * to be dropped
<keithamus> vmpstr: because of the syntax currently specified, universal selector with class you need to spell out *.foo. We'd like to resolve to have * optional if you're using class param. Would look similar to how CSS looks with .class. Other point is that if we dont have a class, Id prefer to require a * - not requiring ()
<fantasai> +1 to the proposal
<keithamus> emilio: how are they defined? Selector syntax? Or custom
<keithamus> vmpstr: custom
<keithamus> khush: args to pseudo element
<keithamus> vmpstr: yes, syntax to the arg is specified in VT spec
<keithamus> astearns: you're talking about omitting * if using class? This is not just optionally omitting but making *.class syntax invalid?
<keithamus> vmpstr: no, optionally
<khush> +1
<keithamus> PROPOSED RESOLUTION: Make * optional if you are using a class.
<emilio> Sgtm
<keithamus> RESOLVED: Make * optional if you are using a class.
<keithamus> astearns: also omitting parens entirely?
<keithamus> vmpstr: the way the resolution is phrased Im happy. If its optional altogether Id like it to not be optional. This resolution satisfies that.
<keithamus> astearns: can scroll go to next week or?
<keithamus> fantasai: no, this one is about alignment property.

I guess whitespaces are invalid between tokens matching these productions.

<pt-name-and-class-selector> = <pt-name-selector><pt-class-selector>? | <pt-class-selector>
<pt-class-selector> = ['.' <custom-ident>]+

Would it be possible to clarify it explicitly (like for selector productions), and add a whitespace between <pt-name-selector> and <pt-class-selector>??
