Has the ::-webkit-selection selector ever been supported?

问题

There are a few references on the internet to ::-webkit-selection, a WebKit-specific version of the ::selection selector.

See e.g. http://www.quirksmode.org/css/selection.html (Edit: PPK has since removed ::-webkit-selection from that page.)

However, I haven’t been able to get the example in the page above, or my own examples, to work in any WebKit-based browser. I’ve tried:

• Safari
  • 1.0
  • 1.2
  • 2.0
  • 3.0
  • 4.0
  • 5.0
  • 5.1
• Chrome
  • 2
  • 6
  • 14

The unprefixed ::selection selector works in all of these browsers anyway, so it’s not really a problem. But I was wondering where the references to the WebKit-specific version of this selector had come from.

Has anyone ever used it?

回答1:

I’ve tested all the way back to Safari 1.0 (using Multi-Safari), and no version supports ::-webkit-selection (and they all do support ::selection).

Unless this is an issue with Multi-Safari, ::-webkit-selection has never been supported in Safari post-1.0. I guess it might have been in the public beta though.
