Re: Css scroll

Hi
We discussed this onthe call  with regard
https://drafts.csswg.org/css-scrollbars-1/

I think we would like the notes to included

 warning for reduced accessibility and useability, especially for  people
with low vision and or people with learning and cognitive disabilities for:


   -  making the  scroll bar thin or none
   -  reducing the contrast of the scroll

Useability testing should included these user groups, when reducing the
size or contrast of scrolls bars



Also we would like to mention that double or nested  scroll bars is often
an accessibility  issue and they should be avoided. If they are
necessary there should be  very clearly grouped with the related content,
so that users can clearly tell what content will be affected by what scroll
bar.


Does this wording work for everyone?

All the best... Lisa
