I was wondering what does the operators and, only, not and the comma , do and mean when used with the media queries?
Are there any other operators that can be used with the media queries?
Please read the Media Queries Specification, it's only 1 page long. In summary though:
and means both things must match, means one of the things must match not means the query is true when it doesn't match only is mentioned in the spec but I can't find a definition. I suspect it does nothing.
