Interactive rating component, using HTML, CSS and JS

Hello Leonardo Araujo, how are you? I truly loved your project's outcome, however I have some advice that I hope you'll find useful:

To make the submit button work only when the user selects a number, we can make some changes:

rates.forEach((rate) => {
    rate.addEventListener("click", () => {
        rating.innerHTML = rate.innerHTML
        btnSubmit.addEventListener('click', () => {
            thankyouContainer.classList.remove("hidden")
            mainContainer.style.display = "none"
        })
    })
})

The remainder is excellent.

I hope it's useful. 👍
