Similar to #11053, the css-ui-4 has a redundant group around the
outline
property value. It is currently specified as[ <'outline-width'> || <'outline-style'> || <'outline-color'> ]
, but I think it could be better expressed without the[]
, as<'outline-width'> || <'outline-style'> || <'outline-color'>
instead.I'd like to point out that
caret
has similar shape, and is expressed as<'caret-color'> || <'caret-animation'> || <'caret-shape'>
. So I think both should be have a consistent syntax.
