Hello all,

I do believe that the gradient that is seen on this page should never be 
allow to work.


Even for an author who may have worked with some gradients, the results 
of using such small distances between color stops could cause someone 
with photosensitive epilepsy [1] to have a seizure without warning. I 
myself find it hard to scroll this gradient.

I do suggest that the CSS WG get feedback from several people who are 
qualified in the field of photosensitive epilepsy regarding certain 
gradients and animations.

I myself have always been careful in the use of color with my test and 
demos. I do avoid using large segments of red, yellow or fuchsia as 
background colors. This is since my wife has a form of photosensitive 
epilepsy. I will be changing some of my own animations (increasing 
transparency). One has already been changed.
