[css-values] Re-adding min() and max()? #544
Description
Perhaps now that Values 3 has gone to CR it's time to reconsider adding min() and max() back into Values 4?
Authors are doing extremely weird hacks with calc() to emulate them in font-size and line-height, which they call "CSS locks". If you google CSS locks you will see how widespread these hacks are becoming, indicating a clear author need.
Furthermore, as CSS variables become more widely used, the need for min() and max() will become even greater. I recall some of the issues that made us drop them 6 years ago can now be solved with the invalid at computed value time concept that Variables introduced.
