Ask HN: Do you use odd numbers or prime numbers in CSS

I see from your article at https://medium.com/dharma-experiments/join-a-startup-to-acce... and your comments at https://news.ycombinator.com/item?id=9574548 and https://news.ycombinator.com/item?id=5861582 that the prime numbers 2, 5, and 7 are not something you are not prevented from using in non-CSS, so I hope it's okay for me to use them as examples in a comment without triggering any undesired reactions.

I do not have such a issue. Looking through my CSS I do use such numbers. For example, I have an H1 definition which is 2em, and I have color definitions which are primes or odd numbers encoded as 6 hex digits.

In many cases I could use a decimal number, like "5.000004" instead of 5, or represent color as float rgb() values.

If it's the physical representation of the number, rather than the concept, which affects you, then a preprocessor like SASS would let you write "70/10" as a substitute for 7, etc.

This will be less maintainable, and if you have any co-workers you may have difficulty maintaining round-about solutions to represent values comfortably, give that few others will even notice that a 4 digit value like a year, or a hex, is odd, much less prime.

Last year, at https://news.ycombinator.com/item?id=9568640 , you made a reference about how HN's CSS changed from 9pt to 10pt. This makes me wonder if your OCD has recently become worse. If so, that may be something you need to talk to a professional about, rather than ill-informed HN readers like myself.
