I tortured myself over a particular piece of emptiness. Not the existential void we’re thrown in by our creator, but the space I put before url in
@import url ("../twentytwelve/style.css");
This is for wordpress stylesheet development, and with the space, the child theme doesn’t load up the parent style.css. I just corrected it to
@import url("../twentytwelve/style.css");
and it’s working fine. I hope that this post if useful for whoever just stumbled upon it.
