polymer-elements polymer-flex-layout / polymer-flex-layout.css still use
::-webkit-distributed(p) {
color: red;
}
which also works in my recent version of Dartium. I have no idea when the new selectors take effect.
Other polymer-elements that make use of this selector but have recently switched to ::content
- polymer-ui-field
- polymer-ui-menu-item
- polymer-ui-nav-arrow
- polymer-ui-pages
- polymer-ui-sidebar
- polymer-ui-toolbar
You can browse the history to find the previous webkit-distributed selector examples.
I guess they use Chromium which may be a little ahead of Dartium.
