CSS: "already been defined" on different media #300
Description
If you have one or more @media in your css file and you define different rules for the same element on each media, lint mark the second one with a "TagName has already been defined" error.
Example (both declarations are in the same css file of course):
h1 { color: red; }
@media print {
h1 { color: black; } /* lint mark this as a duplicate */
}
