Yesterday, Jessica Burnett asked this question: https://codereview.stackexchange.com/questions/14209/css-set-string-content-properties.
Since the question is about code that does not work (as opposed to code that could be improved), ANeves politely suggested to the OP to post such questions on Stack Overflow. So far so good.
However, today ANeves & Michael K closed the question as being off-topic.
Is this our policy here, to close questions that are suitable for other StackExchange sites? Somehow I had gotten the feeling that such questions should rather be migrated to their proper home!?
