-
-Arguments:
-
-* `props (object)`: The new node's properties.
-
-## Node types
-
-### `node.type`
-
-A string representation of the selector type. It can be one of the following;
-`attribute`, `class`, `combinator`, `comment`, `id`, `nesting`, `pseudo`,
-`root`, `selector`, `string`, `tag`, or `universal`. Note that for convenience,
-these constants are exposed on the main `parser` as uppercased keys. So for
-example you can get `id` by querying `parser.ID`.
-
-```js
-parser.attribute({attribute: 'href'}).type;
-// => 'attribute'
-```
-
-### `node.parent`
-
-Returns the parent node.
-
-```js
-root.nodes[0].parent === root;
-```
-
-### `node.toString()`, `String(node)`, or `'' + node`
-
-Returns a string representation of the node.
-
-```js
-var id = parser.id({value: 'search'});
-console.log(String(id));
-// => #search
-```
-
-### `node.next()` & `node.prev()`
-
-Returns the next/previous child of the parent node.
-
-```js
-var next = id.next();
-if (next && next.type !== 'combinator') {
-    throw new Error('Qualified IDs are not allowed!');
-}
-```
-
-### `node.replaceWith(node)`
-
-Replace a node with another.
-
-```js
-var attr = selectors.first.first;
-var className = parser.className({value: 'test'});
-attr.replaceWith(className);
-```
-
-Arguments:
-
-* `node`: The node to substitute the original with.
-
-### `node.remove()`
-
-Removes the node from its parent node.
-
-```js
-if (node.type === 'id') {
-    node.remove();
-}
-```
-
-### `node.clone()`
-
-Returns a copy of a node, detached from any parent containers that the
-original might have had.
-
-```js
-var cloned = parser.id({value: 'search'});
-String(cloned);
-
-// => #search
-```
-
-### `node.spaces`
-
-Extra whitespaces around the node will be moved into `node.spaces.before` and
-`node.spaces.after`. So for example, these spaces will be moved as they have
-no semantic meaning:
-
-```css
-      h1     ,     h2   {}
-```
-
-However, *combinating* spaces will form a `combinator` node:
-
-```css
-h1        h2 {}
-```
-
-A `combinator` node may only have the `spaces` property set if the combinator
-value is a non-whitespace character, such as `+`, `~` or `>`. Otherwise, the
-combinator value will contain all of the spaces between selectors.
-
-### `node.source`
-
-An object describing the node's start/end, line/column source position.
-
-Within the following CSS, the `.bar` class node ...
-
-```css
-.foo,
-  .bar {}
-```
-
-... will contain the following `source` object.
-
-```js
-source: {
-    start: {
-        line: 2,
-        column: 3
-    },
-    end: {
-        line: 2,
-        column: 6
-    }
-}
-```
-
-### `node.sourceIndex`
-
-The zero-based index of the node within the original source string.
-
-Within the following CSS, the `.baz` class node will have a `sourceIndex` of `12`.
-
-```css
-.foo, .bar, .baz {}
-```
-
-## Container types
-
-The `root`, `selector`, and `pseudo` nodes have some helper methods for working
-with their children.
-
-### `container.nodes`
-
-An array of the container's children.
-
-```js
-// Input: h1 h2
-selectors.at(0).nodes.length   // => 3
-selectors.at(0).nodes[0].value // => 'h1'
-selectors.at(0).nodes[1].value // => ' '
-```
-
-### `container.first` & `container.last`
-
-The first/last child of the container.
-
-```js
-selector.first === selector.nodes[0];
-selector.last === selector.nodes[selector.nodes.length - 1];
-```
-
-### `container.at(index)`
-
-Returns the node at position `index`.
-
-```js
-selector.at(0) === selector.first;
-selector.at(0) === selector.nodes[0];
-```
-
-Arguments:
-
-* `index`: The index of the node to return.
-
-### `container.index(node)`
-
-Return the index of the node within its container.
-
-```js
-selector.index(selector.nodes[2]) // => 2
-```
-
-Arguments:
-
-* `node`: A node within the current container.
-
-### `container.length`
-
-Proxy to the length of the container's nodes.
-
-```js
-container.length === container.nodes.length
-```
-
-### `container` Array iterators
-
-The container class provides proxies to certain Array methods; these are:
-
-* `container.map === container.nodes.map`
-* `container.reduce === container.nodes.reduce`
-* `container.every === container.nodes.every`
-* `container.some === container.nodes.some`
-* `container.filter === container.nodes.filter`
-* `container.sort === container.nodes.sort`
-
-Note that these methods only work on a container's immediate children; recursive
-iteration is provided by `container.walk`.
-
-### `container.each(callback)`
-
-Iterate the container's immediate children, calling `callback` for each child.
-You may return `false` within the callback to break the iteration.
-
-```js
-var className;
-selectors.each(function (selector, index) {
-    if (selector.type === 'class') {
-        className = selector.value;
-        return false;
-    }
-});
-```
-
-Note that unlike `Array#forEach()`, this iterator is safe to use whilst adding
-or removing nodes from the container.
-
-Arguments:
-
-* `callback (function)`: A function to call for each node, which receives `node`
-  and `index` arguments.
-
-### `container.walk(callback)`
-
-Like `container#each`, but will also iterate child nodes as long as they are
-`container` types.
-
-```js
-selectors.walk(function (selector, index) {
-    // all nodes
-});
-```
-
-Arguments:
-
-* `callback (function)`: A function to call for each node, which receives `node`
-  and `index` arguments.
-
-This iterator is safe to use whilst mutating `container.nodes`,
-like `container#each`.
-
-### `container.walk` proxies
-
-The container class provides proxy methods for iterating over types of nodes,
-so that it is easier to write modules that target specific selectors. Those
-methods are:
-
-* `container.walkAttributes`
-* `container.walkClasses`
-* `container.walkCombinators`
-* `container.walkComments`
-* `container.walkIds`
-* `container.walkNesting`
-* `container.walkPseudos`
-* `container.walkTags`
-* `container.walkUniversals`
-
-### `container.split(callback)`
-
-This method allows you to split a group of nodes by returning `true` from
-a callback. It returns an array of arrays, where each inner array corresponds
-to the groups that you created via the callback.
-
-```js
-// (input) => h1 h2>>h3
-var list = selectors.first.split((selector) => {
-    return selector.type === 'combinator';
-});
-
-// (node values) => [['h1', ' '], ['h2', '>>'], ['h3']]
-```
-
-Arguments:
-
-* `callback (function)`: A function to call for each node, which receives `node`
-  as an argument.
-
-### `container.prepend(node)` & `container.append(node)`
-
-Add a node to the start/end of the container. Note that doing so will set
-the parent property of the node to this container.
-
-```js
-var id = parser.id({value: 'search'});
-selector.append(id);
-```
-
-Arguments:
-
-* `node`: The node to add.
-
-### `container.insertBefore(old, new)` & `container.insertAfter(old, new)`
-
-Add a node before or after an existing node in a container:
-
-```js
-selectors.walk(function (selector) {
-    if (selector.type !== 'class') {
-        var className = parser.className({value: 'theme-name'});
-        selector.parent.insertAfter(selector, className);
-    }
-});
-```
-
-Arguments:
-
-* `old`: The existing node in the container.
-* `new`: The new node to add before/after the existing node.
-
-### `container.removeChild(node)`
-
-Remove the node from the container. Note that you can also use
-`node.remove()` if you would like to remove just a single node.
-
-```js
-selector.length // => 2
-selector.remove(id)
-selector.length // => 1;
-id.parent       // undefined
-```
-
-Arguments:
-
-* `node`: The node to remove.
-
-### `container.removeAll()` or `container.empty()`
-
-Remove all children from the container.
-
-```js
-selector.removeAll();
-selector.length // => 0
-```
-
-## Root nodes
-
-A root node represents a comma separated list of selectors. Indeed, all
-a root's `toString()` method does is join its selector children with a ','.
-Other than this, it has no special functionality and acts like a container.
-
-### `root.trailingComma`
-
-This will be set to `true` if the input has a trailing comma, in order to
-support parsing of legacy CSS hacks.
-
-## Selector nodes
-
-A selector node represents a single compound selector. For example, this
-selector string `h1 h2 h3, [href] > p`, is represented as two selector nodes.
-It has no special functionality of its own.
-
-## Pseudo nodes
-
-A pseudo selector extends a container node; if it has any parameters of its
-own (such as `h1:not(h2, h3)`), they will be its children. Note that the pseudo
-`value` will always contain the colons preceding the pseudo identifier. This
-is so that both `:before` and `::before` are properly represented in the AST.
-
-## Attribute nodes
-
-### `attribute.quoted`
-
-Returns `true` if the attribute's value is wrapped in quotation marks, false if it is not.
-Remains `undefined` if there is no attribute value.
-
-```css
-[href=foo] /* false */
-[href='foo'] /* true */
-[href="foo"] /* true */
-[href] /* undefined */
-```
-
-### `attribute.raws.unquoted`
-
-Returns the unquoted content of the attribute's value.
-Remains `undefined` if there is no attribute value.
-
-```css
-[href=foo] /* foo */
-[href='foo'] /* foo */
-[href="foo"] /* foo */
-[href] /* undefined */
-```
-
-### `attribute.raws.insensitive`
-
-If there is an `i` specifying case insensitivity, returns that `i` along with the whitespace
-around it.
-
-```css
-[id=Bar i ] /* " i " */
-[id=Bar   i  ] /* "   i  " */
-```
-
-## `processor`
-
-### `process(cssText, [options])`
-
-Processes the `cssText`, returning the parsed output
-
-```js
-var processor = parser();
-
-var result = processor.process(' .class').result;
-// =>  .class
-
-// To have the parser normalize whitespace values, utilize the options
-var result = processor.process('  .class  ', {lossless: false}).result;
-// => .class
-```
-
-Arguments:
-
-* `cssText (string)`: The css to be parsed.
-* `[options] (object)`: Process options
-
-Options:
-
-* `lossless (boolean)`: false to normalize the selector whitespace, defaults to true
