JavaScript DOM Scripting By Example Adding and Removing Names Practice with Function Scope

thediv with the ID colorDiv should change red when the red button is clicked, and blue when the blue button is clicked.

I cut the second part of the code in redButton but didn't passed.

app.js
const redButton = document.getElementById('redButton');
const blueButton = document.getElementById('blueButton');

redButton.addEventListener('click', (e) => {
  colorSquare.style.backgroundColor = 'red';
});

blueButton.addEventListener('click', (e) => {
  colorSquare.style.backgroundColor = 'blue';
})
style.css
div {
  height: 50px;
  float: left;
  padding-top: 40px;
  padding-left: 20px;

}

#colorDiv {
  padding: 0;
  width: 100px;
  height: 100px;
  background-color: gray;
}

button {
  height: 30px;
  border-radius: 10px;
}
#redButton {
  background-color: #ff5959;
  border-color: red;
}

#blueButton {
  background-color: lightblue;
  border-color: #7C9EFC;
}

Your code didn't include the HTML or a reference in the javascript to colorSquare. I added those in and it worked just fine.

Yep, like Mark said, you should just need to declare the variable for colorSquare.

const colorSquare = document.getElementById('colorDiv');

Thank you guys, now it worked.
