How to use non standard CSS selectors in a CSSResource

I am trying to use styles for the scrollbars in webkit. The CSS selectors look like this:

::-webkit-scrollbar-corner
::-webkit-scrollbar-track-piece:disabled

and so on.

When I use those in a ClientBundle开发者_StackOverflow中文版 as a CSSResource, the compiler is complaining about those selectors. This results in warnings during compile time, not errors.

But those styles aren't being applied.

I tried to escape the colons, dashes etc. without luck. The literal function doesn't apply here either as it is only used in combination with values, not selectors.

I also used the @external annotation to avoid obfuscation of the selectors.

Nothing seems to work.

Has anyone an idea how to get those styles into my ClientBundle?

Greetings, Matthias

You can use "Literal function" for non standard CSS definitions http://code.google.com/p/google-web-toolkit/wiki/CssResource#Literal_function
