# Create a notification

Write a function `showNotification(options)` that creates a notification: `<div class="notification">` with the given content. The notification should automatically disappear after 1.5 seconds.

The options are:

```js
// shows an element with the text "Hello" near the right-top of the window
showNotification({
  top: 10, // 10px from the top of the window (by default 0px)
  right: 10, // 10px from the right edge of the window (by default 0px)
  html: "Hello!", // the HTML of notification
  className: "welcome" // an additional class for the div (optional)
});
```
