CSS Hack for Google Chrome

[Alexancho]

I need a one div to be in Chrome only, so i used a code:
div.chrome_hack{
display:none;
}
@media screen and (-webkit-min-device-pixel-ratio:0)
{
div.chrome_hack{
display:block;
}
}
It works, but causes a validation error:
110 Property -webkit-min-device-pixel-ratio doesn't exist for media screen : 0 0

Is there a better solution?
And if there isn't can we say this solution is correct?

That's the best solution out there. Really, you're CSS is fine, it's just that the validator doesn't know that one small thing (Which is good, you only want Chrome [Safari gets it too] to see it.) so it calls it as an error.

Thank you very much!
