Currently the CSS > property does not have an "auto" value. Yes, I was referring to the CSS property. It seems to me having an 'auto' value for that property that falls back to UA/platform defaults would be better than making 'smooth' do that. In particular it seems that currently "smooth" in the JS API overrides UA defaults but CSS scroll-behavior:smooth does not override UA defaults. It would be better if they were consistent. > But then I'm not sure what the use-cases are for the "initial" and >> "smooth" >> values of scroll-behavior. >> > > "instant" is the initial value, and gives the same behavior as we have > today. > > "smooth" allows the UA to do the scroll over a period of time in a > UA-defined manner for scrolls triggered from navigation and from the > scrolling APIs (unless the script specified "instant" or "smooth" > explicitly). > > For use cases, please see http://www.w3.org/mid/op. > ww4mdlp2idj3kv@simons-macbook-pro.local > Thanks. I guess that makes sense though it means scroll-behavior is a very narrowly-useful property. I'm not sure it's worth having to be honest, assuming we add the JS API.
