Hi All,
I’m not sure if this has already been addressed, but I noticed that my CSS language grammar highlights “transparent” in {background-color: transparent;}, and most everything after that, as an error (scope = invalid.illegal.css). The more common {background: transparent;} doesn’t trigger the error, and in that case “transparent” gets the scope “name = 'support.constant.property-value.css'.” I added transparent to the value list in “name = 'support.constant.color.w3c-standard- color-name.css',” which may not be the right place, but works for me.
