An element is considered as invalid when one of these match:

* `disabled` or visibility is `hidden`

* one of it's parentNode display is `none` or visibility is `hidden`

An element is not considered invalid when it's not disabled and itself display is `none` (you may need to hide the real input and use

other component for user input).

## Install

    npm i invalid-component

## Usage

```

var invalid = require('invalid-component')

el.parentNode.style.display = 'none'

invalid(el) //true

```
