Check if a DOM node is descended from another node or selector.

## Installation

```
npm install descended-from
```

## Usage

```
var descendedFrom = require('descended-from');

var child = document.getElementById('child');
var parent = document.getElementById('parent');

descendedFrom(child, parent) // -> true
```

given this DOM

```
<div id="parent">
  <div>
    <div id="child"></div>
  </div>
</div>
```

This is equivalent running `parent.contains(child)`. However you can do more with `descended-from`.

### Check if descended from an element with a class

```
var child = document.getElementById('child');

descendedFrom(child, '.parent') // -> true
```

given this DOM

```
<div class="parent">
  <div>
    <div id="child"></div>
  </div>
</div>
```

### Check if descended from an element with an ID

```
var child = document.getElementById('child');

descendedFrom(child, '#parent') // -> true
```

given this DOM

```
<div id="parent">
  <div>
    <div id="child"></div>
  </div>
</div>
```

## Browser support

Chrome 1+, Firefox 3.5+, IE 9+, Opera 10.5+, Safari 5+

Browser functions depended on so far are:
- `element.classList()`
- `element.contains()`
- `string.trim()`
