declaration-property-value-whitelist

Specify a whitelist of allowed property and value pairs within declarations.

a { text-transform: uppercase; }
/** ↑               ↑
 * These properties and these values */

选项

object: { "unprefixed-property-name": ["array", "of", "values"], "unprefixed-property-name": ["/regex/", "non-regex"] }

If a property name is found in the object, only its whitelisted property values are allowed. This rule complains about all non-matching values. (If the property name is not included in the object, anything goes.)

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": ["/scale/"],
  "whitespace": ["nowrap"],
  "/color/": ["/^green/"]
}

以下模式被视为违规：

a { whitespace: pre; }
a { transform: translate(1, 1); }
a { -webkit-transform: translate(1, 1); }
a { color: pink; }
a { background-color: pink; }

以下模式不被视为违规：

a { color: pink; }
a { whitespace: nowrap; }
a { transform: scale(1, 1); }
a { -webkit-transform: scale(1, 1); }
a { color: green; }
a { background-color: green; }
a { background: pink; }
