## .wrap()

Wraps the matched element(s) with the passed argument. The argument gets processed with the constructor u() and it accepts an html tag like ```.wrap('<div>')```

```js
.wrap(selector);
```


### Parameters

`selector`: a formatted string of the desired selector. For example ```.wrap('<div>')```. Nested selectors are supported in a similar way to [jQuery wrap](http://api.jquery.com/wrap/). For example ```.wrap('<div class="a1"><div class="b1"><div class="c1"></div></div></div>')```. Matched element(s) will be wrapped with innermost node of the first child of a nested argument. See examples below.



### Return

`u`: returns an instance of Umbrella JS with the wrapped node(s)
