### Instructions
Now that you know how to make your creation move, what about making it communicate its first words to the world?
Let's put a second button in the top right corner of the page, that will add some text when clicked.
Add it in the HTML structure:
```
<button id="speak-button">Click me to speak</button>
```
Add the button style in the CSS file:
```
button#speak-button {
top: 100px;
}
```
Also add this class to style the text we will add:
```
.words {
text-align: center;
font-family: sans-serif;
}
```
In the JS file, like in the previous exercise, get the HTML button element with `id` `speak-button` and add an event listener on `click` event, triggering a function that will:
- [create a new HTML element](https://developer.mozilla.org/en-US/docs/Web/API/Document/createElement) of type `div`
- set its [text content](https://developer.mozilla.org/en-US/docs/Web/API/Node/textContent) to "Hello there!"
- set its [`className`](https://developer.mozilla.org/en-US/docs/Web/API/Element/className) to `words`, that we just added earlier in the CSS
- use the [`append`](https://developer.mozilla.org/en-US/docs/Web/API/ParentNode/append) method to add it inside the `torso` element
### Code examples
Create a new element and add it inside the body:
```js
// create a new `div` element
const div = document.createElement('div') // the argument passed (string) is the html tag
// select the `body` and add the new `div` inside it
const body = document.querySelector('body')
body.append(div)
```
