Specify a blacklist of disallowed property and value pairs within declarations.
指定一个在声明中禁止使用的属性和值的黑名单。
a { text-transform: uppercase; }
/** ↑ ↑
* These properties and these values */
object: {
"unprefixed-property-name": ["array", "of", "values"],
"unprefixed-property-name": ["/regex/", "non-regex"]
}
If a property name is surrounded with "/"
(e.g. "/^animation/"
), it is interpreted as a regular expression. This allows, for example, easy targeting of shorthands: /^animation/
will match animation
, animation-duration
, animation-timing-function
, etc.
如果一个字符串被 "/"
(如,"/^animation/"
) 包围,它将被解释为一个正则表达式。例如,这将允许简单地匹配简写: /^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/"
.
这样的处理同样适用于值。记住,一个正则表达式匹配整个值,而不是特定的某一部分。比如,"10px solid rgba( 255 , 0 , 0 , 0.5 )"
不会匹配 "/^solid/"
,但会匹配 "/\\s+solid\\s+/"
或 "/\\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)"
.
注意,正则表达式匹配不考虑引号内的字符串和 url()
中的参数,比如,"/red/"
不匹配像 "1px dotted red"
,"\"foo\""
和 "white url(/mysite.com/red.png)"
的值,
Given:
给出:
{
"transform": ["/scale3d/", "/rotate3d/", "/translate3d/"],
"position": ["fixed"],
"color": ["/^green/"],
"/^animation/": ["/ease/"]
}
The following patterns are considered warnings:
以下模式被认为是个警告:
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; }
The following patterns are not considered warnings:
以下模式正常:
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; }
