Custom Element v1 scoped styling
Closed this issue · 1 comments
Thanks for the site. Very useful.
One thing I didn't see was mention of Custom Element v1 scoped styling.
https://github.com/polymer/polymer/tree/2.0-preview#v1-custom-elements
Thanks for the feedback.
I think ::content
, ::slotted
,/deep/
, and ::shadow
are already mentioned.
Given that, I guess you meant :host-context()
pseudo-selectors, right?
That page said:
:host-context() pseudo-selectors have been removed.
However, I think this sentence might be confusing. Blink has not removed :host-context()
, which is now being defined in CSS Scoping spec. You can use :host-context()
in Blink.
I guess that the intention is that "Polymer 2.0 is no longer using :host-context()
".
As far as I know, Polymer folks decided to use :host(:dir(...))
, instead of :host-context()
because WebKit @did not have a plan to support :host-context()
.
