+# declaration-property-value-whitelist
+
+Specify a whitelist of allowed property and value pairs within declarations.
+
+```css
+a { text-transform: uppercase; }
+/** ↑ ↑
+ * These properties and these values */
+```
+
+## Options
+
+`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.)
+
+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.
+
+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)"`.
+
+Given:
+
+```js
+{
+ "transform": ["/scale/"],
+ "whitespace": ["nowrap"],
+ "/color/": ["/^green/"]
+}
+```
+
+The following patterns are considered violations:
+
+```css
+a { whitespace: pre; }
+```
+
+```css
+a { transform: translate(1, 1); }
+```
+
+```css
+a { -webkit-transform: translate(1, 1); }
+```
+
+```css
+a { color: pink; }
+```
+
+```css
+a { background-color: pink; }
+```
+
+The following patterns are *not* considered violations:
+
+```css
+a { color: pink; }
+```
+
+```css
+a { whitespace: nowrap; }
+```
+
+```css
+a { transform: scale(1, 1); }
+```
+
+```css
+a { -webkit-transform: scale(1, 1); }
+```
+
+```css
+a { color: green; }
+```
+
+```css
+a { background-color: green; }
+```
+
+```css
+a { background: pink; }
+```
