+# [postcss][postcss]-normalize-string
+
+> Normalize strings with PostCSS.
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-normalize-string) do:
+
+```
+npm install postcss-normalize-string --save
+```
+
+## Example
+
+### Input
+
+```css
+p:after{ content: '\\'string\\' is intact' }
+```
+
+### Output
+
+```css
+p:after{ content:"'string' is intact" }
+```
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
+
+## API
+
+### normalize([options])
+
+#### options
+
+##### preferredQuote
+
+Type: `string`
+Default: `double`
+
+Sets what type of quote to prefer. Possible values are `single` and `double`.
+
+```js
+var css = 'p:after{content:""}';
+console.log(postcss(normalize({preferredQuote: 'single'})).process(css).css);
+//=> p:after{content:''}
+```

+# postcss-value-parser
+
+[![Travis CI](https://travis-ci.org/TrySound/postcss-value-parser.svg)](https://travis-ci.org/TrySound/postcss-value-parser)
+
+Transforms CSS declaration values and at-rule parameters into a tree of nodes, and provides a simple traversal API.
+
+## Usage
+
+```js
+var valueParser = require('postcss-value-parser');
+var cssBackgroundValue = 'url(foo.png) no-repeat 40px 73%';
+var parsedValue = valueParser(cssBackgroundValue);
+// parsedValue exposes an API described below,
+// e.g. parsedValue.walk(..), parsedValue.toString(), etc.
+```
+
+For example, parsing the value `rgba(233, 45, 66, .5)` will return the following:
+
+```js
+{
+  nodes: [
+    {
+      type: 'function',
+      value: 'rgba',
+      before: '',
+      after: '',
+      nodes: [
+        { type: 'word', value: '233' },
+        { type: 'div', value: ',', before: '', after: ' ' },
+        { type: 'word', value: '45' },
+        { type: 'div', value: ',', before: '', after: ' ' },
+        { type: 'word', value: '66' },
+        { type: 'div', value: ',', before: ' ', after: '' },
+        { type: 'word', value: '.5' }
+      ]
+    }
+  ]
+}
+```
+
+If you wanted to convert each `rgba()` value in `sourceCSS` to a hex value, you could do so like this:
+
+```js
+var valueParser = require('postcss-value-parser');
+
+var parsed = valueParser(sourceCSS);
+
+// walk() will visit all the of the nodes in the tree,
+// invoking the callback for each.
+parsed.walk(function (node) {
+
+  // Since we only want to transform rgba() values,
+  // we can ignore anything else.
+  if (node.type !== 'function' && node.value !== 'rgba') return;
+
+  // We can make an array of the rgba() arguments to feed to a
+  // convertToHex() function
+  var color = node.nodes.filter(function (node) {
+    return node.type === 'word';
+  }).map(function (node) {
+    return Number(node.value);
+  }); // [233, 45, 66, .5]
+
+  // Now we will transform the existing rgba() function node
+  // into a word node with the hex value
+  node.type = 'word';
+  node.value = convertToHex(color);
+})
+
+parsed.toString(); // #E92D42
+```
+
+## Nodes
+
+Each node is an object with these common properties:
+
+- **type**: The type of node (`word`, `string`, `div`, `space`, `comment`, or `function`).
+  Each type is documented below.
+- **value**: Each node has a `value` property; but what exactly `value` means
+  is specific to the node type. Details are documented for each type below.
+- **sourceIndex**: The starting index of the node within the original source
+  string. For example, given the source string `10px 20px`, the `word` node
+  whose value is `20px` will have a `sourceIndex` of `5`.
+
+### word
+
+The catch-all node type that includes keywords (e.g. `no-repeat`),
+quantities (e.g. `20px`, `75%`, `1.5`), and hex colors (e.g. `#e6e6e6`).
+
+Node-specific properties:
+
+- **value**: The "word" itself.
+
+### string
+
+A quoted string value, e.g. `"something"` in `content: "something";`.
+
+Node-specific properties:
+
+- **value**: The text content of the string.
+- **quote**: The quotation mark surrounding the string, either `"` or `'`.
+- **unclosed**: `true` if the string was not closed properly. e.g. `"unclosed string  `.
+
+### div
+
+A divider, for example
+
+- `,` in `animation-duration: 1s, 2s, 3s`
+- `/` in `border-radius: 10px / 23px`
+- `:` in `(min-width: 700px)`
+
+Node-specific properties:
+
+- **value**: The divider character. Either `,`, `/`, or `:` (see examples above).
+- **before**: Whitespace before the divider.
+- **after**: Whitespace after the divider.
+
+### space
+
+Whitespace used as a separator, e.g. ` ` occurring twice in `border: 1px solid black;`.
+
+Node-specific properties:
+
+- **value**: The whitespace itself.
+
+### comment
+
+A CSS comment starts with `/*` and ends with `*/`
+
+Node-specific properties:
+
+- **value**: The comment value without `/*` and `*/`
+- **unclosed**: `true` if the comment was not closed properly. e.g. `/* comment without an end  `.
+
+### function
+
+A CSS function, e.g. `rgb(0,0,0)` or `url(foo.bar)`.
+
+Function nodes have nodes nested within them: the function arguments.
+
+Additional properties:
+
+- **value**: The name of the function, e.g. `rgb` in `rgb(0,0,0)`.
+- **before**: Whitespace after the opening parenthesis and before the first argument,
+  e.g. `  ` in `rgb(  0,0,0)`.
+- **after**: Whitespace before the closing parenthesis and after the last argument,
+  e.g. `  ` in `rgb(0,0,0  )`.
+- **nodes**: More nodes representing the arguments to the function.
+- **unclosed**: `true` if the parentheses was not closed properly. e.g. `( unclosed-function  `.
+
+Media features surrounded by parentheses are considered functions with an
+empty value. For example, `(min-width: 700px)` parses to these nodes:
+
+```js
+[
+  {
+    type: 'function', value: '', before: '', after: '',
+    nodes: [
+      { type: 'word', value: 'min-width' },
+      { type: 'div', value: ':', before: '', after: ' ' },
+      { type: 'word', value: '700px' }
+    ]
+  }
+]
+```
+
+`url()` functions can be parsed a little bit differently depending on
+whether the first character in the argument is a quotation mark.
+
+`url( /gfx/img/bg.jpg )` parses to:
+
+```js
+{ type: 'function', sourceIndex: 0, value: 'url', before: ' ', after: ' ', nodes: [
+    { type: 'word', sourceIndex: 5, value: '/gfx/img/bg.jpg' }
+] }
+```
+
+`url( "/gfx/img/bg.jpg" )`, on the other hand, parses to:
+
+```js
+{ type: 'function', sourceIndex: 0, value: 'url', before: ' ', after: ' ', nodes: [
+     type: 'string', sourceIndex: 5, quote: '"', value: '/gfx/img/bg.jpg' },
+] }
+```
+
+## API
+
+```
+var valueParser = require('postcss-value-parser');
+```
+
+### valueParser.unit(quantity)
+
+Parses `quantity`, distinguishing the number from the unit. Returns an object like the following:
+
+```js
+// Given 2rem
+{
+  number: '2',
+  unit: 'rem'
+}
+```
+
+If the `quantity` argument cannot be parsed as a number, returns `false`.
+
+*This function does not parse complete values*: you cannot pass it `1px solid black` and expect `px` as
+the unit. Instead, you should pass it single quantities only. Parse `1px solid black`, then pass it
+the stringified `1px` node (a `word` node) to parse the number and unit.
+
+### valueParser.stringify(nodes[, custom])
+
+Stringifies a node or array of nodes.
+
+The `custom` function is called for each `node`; return a string to override the default behaviour.
+
+### valueParser.walk(nodes, callback[, bubble])
+
+Walks each provided node, recursively walking all descendent nodes within functions.
+
+Returning `false` in the `callback` will prevent traversal of descendent nodes (within functions).
+You can use this feature to for shallow iteration, walking over only the *immediate* children.
+*Note: This only applies if `bubble` is `false` (which is the default).*
+
+By default, the tree is walked from the outermost node inwards.
+To reverse the direction, pass `true` for the `bubble` argument.
+
+The `callback` is invoked with three arguments: `callback(node, index, nodes)`.
+
+- `node`: The current node.
+- `index`: The index of the current node.
+- `nodes`: The complete nodes array passed to `walk()`.
+
+Returns the `valueParser` instance.
+
+### var parsed = valueParser(value)
+
+Returns the parsed node tree.
+
+### parsed.nodes
+
+The array of nodes.
+
+### parsed.toString()
+
+Stringifies the node tree.
+
+### parsed.walk(callback[, bubble])
+
+Walks each node inside `parsed.nodes`. See the documentation for `valueParser.walk()` above.
