It can.  CSS Media Query:  http://www.w3.org/TR/css3-mediaqueries/

@media screen and (resolution: 300dpi) { @import url(/300dpi.css); }
@media screen and (resolution: 1200dpi) { @import url(/1200dpi.css);}

Where appropriate, media query keywords can take an optional min- or max-
prefix to convert the equality comparison into a greater than or equal, or
less than or equal.  e.g.

@media screen and (min-resolution: 1200dpi) { @import url(/1200+dpi.css); }
