The best I’ve been able to find is some info about editing my config file. So, following the syntax I have used for the SCSS linter, I used:
"linter-csslint": cssLintExecutablePath: "/usr/local/bin/csslint" cssLintExcludedLinters: [ "ids" "unique-headings" ]
I got the names from this http://csslint.net/about.html
But this seems to have no effect; I am still warned about IDs as selectors.
