[css-images] Typos gradient grammars #6425
Description
I suggest the following changes in the "expanded" grammar of 3.2.1. radial-gradient() Syntax (css-images-3, the note at the very bottom of the section):
Fixed in 09ceac0 and 8f97e89
Expanded with the above definitions, the grammar becomes:
radial-gradient() = radial-gradient(
- [ [ circle || <length> ] [ at <position> ]? , |
- [ ellipse || <length-percentage>{2} ] [ at <position> ]? , |
+ [ [ circle || <length [0,∞]> ] [ at <position> ]? , |
+ [ ellipse || <length-percentage [0,∞]>{2} ] [ at <position> ]? , |
[ [ circle | ellipse ] || <extent-keyword> ] [ at <position> ]? , |
at <position> ,
]?
- <color-stop> [ , <color-stop> ]+
+ <color-stop-list>
)
<extent-keyword> = closest-corner | closest-side | farthest-corner | farthest-sideI believe that <size>s are missing ranges, and that a type extending to a color is missing, because <color-stop> expands to <color-stop-length> | <color-stop-angle>, which only expand to dimension(s)/percentage(s). I think it should be <color-stop-list> instead, or that <color-stop> should be changed there (css-images-4) to:
- <color-stop> = <color-stop-length> | <color-stop-angle>
+ <color-stop> = <linear-color-stop> | <angular-color-stop>
