-## 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);
-```
