When running nanoc check css on https://github.com/dgmstuart/dgms_cv I get the following mystery errors:

Issues found!
  output/stylesheets/styles.css:
    [ ERROR ] css - Parse Error
    [ ERROR ] css - Parse Error

Running my output css through the W3C CSS validator site I can see the source of the problem (apparently the validator currently chokes on the @page selector - used in print stylesheets):

Parse Error @page { margin: 1.2cm; }
Parse Error }

It would be nice if nanoc could display this information as well.

The w3c_validators gem doesn’t return that data in a ready-to-use format, but it does return the lines on which the error occurred, so that should give enough information (hopefully) to create a better error message:

#<W3CValidators::Results:0x007fbe950506f8
  @messages=[
    #<W3CValidators::Message:0x007fbe95058da8
    @type=:error,
    @uri="file://localhost/TextArea",
    @line="1",
    @col=nil,

Fixed by #504. This will be in the next patch release (3.7.5)!
