Will `focus` an element. This will only work if the element is in the `document.body` and if it has an `tabindex` attribute.

```javascript
var a = el('div');
a.appendTo(document.body).focus();
```

### `html` [top](#methods)

Is an interface for `innerHTML`. When passed no arguments, it will return the value of `innerHTML`.

```javascript
var a = el('div');
a.html('test');
// a.node.innerHTML -> 'test'
// a.html() -> 'test'
```
