I think this makes sense |

I'm personally happy to resolve on this, perhaps asynchronously since WG meeting time is hard to get. /cc @jakearchibald |

I still think this is a bad feature with a bad name. But it was force-shipped. |

Is this name exposed to the developer or does it just look like the transition is named auto? If it's exposed, what is the name it's exposed as? |
It should not be exposed, as per previous resolutions it would be |
|
I actually thought this is the behavior we had adopted already. :) I.e. that the ID was used only internally for pairing elements, not otherwise exposed as a view-transition-name. |

The CSS Working Group just discussed
The full IRC log of that discussion<TabAtkins> vmpstr: we added v-t-name:auto<TabAtkins> vmpstr: matches the VT name based on the element's ID attribute, and acts as match-element otherwise <TabAtkins> vmpstr: this name isn't exposed anywhere, it's "auto" in serializations <TabAtkins> vmpstr: but wanted to clarify that the ID ident shouldn't match another VT that specifies a manual ident that happens tob e the same <TabAtkins> vmpstr: Like `v-t-name: foo` on one element and `v-t-name:auto` on an element with id="foo" shouldn't match <TabAtkins> astearns: looks like there's agreement in the thread <TabAtkins> sounds fine to me <TabAtkins> astearns: anyone in the room actually want the behavior we're prohibiting? <TabAtkins> no opinion either way, really, happy to defer to editors <bkardell_> makes sense <noamr> +1 <TabAtkins> fantasai: I thought that's what we'd adopted originally, that the ID would only be used to link elements together, not something exposeable to other CSS. So this makes sense to me. <TabAtkins> vmpstr: proposed: v-t-name:auto will never match an explicit v-t-name:<ident> <TabAtkins> astearns: any objections? <TabAtkins> RESOLVED: v-t-name:auto never matches an explicit v-t-name:<ident> |
…only match other IDs Closes w3c#11614
We have a
view-transition-name: autothat can use theidattribute from the element as the view transition name. (https://www.w3.org/TR/css-view-transitions-2/#auto-vt-name)I think it can be confusing if, for example, in the old state we match
id=fooand on the other side that pairs with cssview-transition-name: foo.The proposal is to "namespace" id matching. Basically
id=foowould only match withid=fooand not withview-transition-name: foo. Or, in other words, names generated by theidattribute can only match elements that have names that are also generated by theidattribute.@nt1m @noamr fyi
