Is a true pure-CSS XOR blend mode possible in 2025?
As an old assembly-language guy, I think about the math in blend modes.
And I was looking at today's CSS Battle Daily and thought it would be really easy and clever if I could toggle between foreground/background colors, by using the XOR of the two values.
But mix-blend "exclusion" isn't really XOR and "difference" only works in one direction. It's not reversible like XOR.
Just something I ponder over about once a year.
I thought I'd ask the hive mind if anyone has come up with a method.

A friendly place for developers to meet other devs, ask questions, get help, and just have a good time 🙂.
