## Colorful legs
> JSPowered Mode
### Context
Your robot is cool, but you can make it even more striking! Or at least, make it show off its colorful legs to everyone!
> Follow the instructions, ask your peers if you are stuck and stay motivated because you are close to the goal!
> Follow every hint you have in the subject!
> Continue on the code from last exercise, and change the file names!
### Instructions
In this exercise, you will use your gained knowledge to make your robot's legs change colors!
#### Task 1:
Let's put another button in the top right corner of the page with an id ``leg-color``, that will change the legs color. Add it in the HTML structure:
```html
<button id="leg-color">Change robot's leg colors</button>
```
Add the button style in the CSS file:
```css
#leg-color
{
position: fixed;
top: 240px;
right: 30px;
padding: 10px;
margin-bottom: 20px;
z-index: 2;
}
```
#### Task 2:
In the JS file, like in the previous exercise, get the following elements:
- The button with the ID ``leg-color``.
- The left and right leg elements with the IDs ``leg-left`` and ``leg-right``.
- Apply the random color to both legs by changing their ``backgroundColor``.
At this point, you know how it goes! make those legs vibrate with beautiful colors!
### Code Example:
```js
// Select the button with id 'leg-color'
//...Here
// Select the left and right legs elements
//...Here
// Your function that gets triggered when clicking the new button
const handleChangeLegColor = (event) => {
// Generate a random color
const randomColor = `#${Math.floor(Math.random() * 16777215).toString(16)}`;
// Apply the random color to both legs
//...Here
};
legColorButton.addEventListener("click", handleChangeLegColor);
```
**``Prompt Example:``**
