it seems that mini-grid is class name and it's missing . before class name in query selector.
This

const displaySquares = document.querySelectorAll('mini-grid div')

should be (notice . before mini-grid)

const displaySquares = document.querySelectorAll('.mini-grid div')
Enter fullscreen mode Exit fullscreen mode
