指定声明内禁用的属性和值对的黑名单。
a { text-transform: uppercase; }
/** ↑ ↑
* 这些属性和值 */
object
: { "unprefixed-property-name": ["array", "of", "values"], "unprefixed-property-name": ["/regex/", "non-regex", /regex/] }
如果属性名称用 "/"
包围(例如 "/^animation/"
),则将其解释为正则表达式。这允许方便的简写,例如:/^animation/
将匹配 animation
、animation-duration
、animation-timing-function
等。
The same goes for values. Keep in mind that a regular expression value is matched against the entire value of the declaration, not specific parts of it. For example, a value like "10px solid rgba( 255 , 0 , 0 , 0.5 )"
will not match "/^solid/"
(notice beginning of the line boundary) but will match "/\\s+solid\\s+/"
or "/\\bsolid\\b/"
.
Be careful with regex matching not to accidentally consider quoted string values and url()
arguments. For example, "/red/"
will match value such as "1px dotted red"
as well as "\"foo\""
and "white url(/mysite.com/red.png)"
.
给定:
{
"transform": ["/scale3d/", "/rotate3d/", "/translate3d/"],
"position": ["fixed"],
"color": ["/^green/"],
"/^animation/": ["/ease/"]
}
以下模式被视为违规:
a { position: fixed; }
a { transform: scale3d(1, 2, 3); }
a { -webkit-transform: scale3d(1, 2, 3); }
a { color: green; }
a { animation: foo 2s ease-in-out; }
a { animation-timing-function: ease-in-out; }
a { -webkit-animation-timing-function: ease-in-out; }
以下模式不被视为违规:
a { position: relative; }
a { transform: scale(2); }
a { -webkit-transform: scale(2); }
a { color: lightgreen; }
a { animation: foo 2s linear; }
a { animation-timing-function: linear; }
a { -webkit-animation-timing-function: linear; }
