Avoid error for ::selection

[romainberger]

Hi,

The tool report the rules for ::selection and ::-moz-selection as duplicate.But for now we need to write the rules for both separately (https://developer.mozilla.org/en/docs/CSS/::selection).
Not a big issues, but thought I could share (awesome project btw and would love to fork but sadly I don't know ruby :( ).

Example with

::-moz-selection {
    background: #000;
    color: #fff;
    text-shadow: none;
}
::selection {
    background: #000;
    color: #fff;
    text-shadow: none;
}

we get the error:

{::-moz-selection} AND {::selection} share 3 rules`

Thanks for the report @romainberger I can see why it would be reported that way based on how csscss is currently written. Are you saying that writing it as:

::-moz-selection, ::selection {
    background: #000;
    color: #fff;
    text-shadow: none;
}

isn't practical from a browser support standpoint?

[romainberger]

Yes, if a browser sees a selector that is invalid for him, it doesn't take in account the whole rule set, so we have to write this kind of thing twice (the link I gave explains it better).

Ah thanks.
