This DOM utility prevents zooming components from hijacking [mouse-wheel events](https://developer.mozilla.org/en-US/docs/Web/API/Element/wheel_event) and interfering with the natural scroll of a page.

By wrapping a child element with this component, wheel events are only propagated downstream if a **modifier key** is pressed (ctrl or meta key - **⌘**, **⊞**), otherwise a message is overlayed informing the user to do so by pressing the key.

## Quick start

```js
import ScrollZoomClamp from 'scroll-zoom-clamp';
```
or using a *script* tag
```html
<script src="//unpkg.com/scroll-zoom-clamp"></script>
```
then
```js
// assuming a parentNode and a childNode element
parentNode.appendChild(
 new ScrollZoomClamp(childNode).node
);
```

## API reference

### Instantiation

The following configuration options are available:

| Config option | Description |
| --- | --- |
| message: str | Ability to customize the message shown when the zoom is blocked. Supports plain text or HTML content. |

### Attributes

| Type | Attribute | Description |
| --- | --- | --- |
| Getter | node | Returns the wrapper DOM element. |
