One of my SOCIS students has actually written about this. It's kind of
a hilarious read:

The reason why I asked about both of these things at once is that it's
actually difficult to have both parity0/parity1 classes *and* make the
code copy-pasteable without line numbers. If I could get rid of the
line numbers, it would simplify matters, since I could use the table
approach or the javascript that my student eventually used.
