What I learned

Learned a lot about manipulating DOM using JavaScript. I was also able to make the site more accessible by not just hiding the default radio inputs but by moving them out of the screen, so they still show up in screen-readers. Also figured out how to add animation to the submit button if no rating is selected and the button is clicked.

To see how you can add code snippets, see below:

.hidden-radio {
    position: absolute;
    left: -9999px;
}

.shake {
    background-color: var(--orange);
    animation: shake 0.5s;
}
  
@keyframes shake {
    0% { transform: translateX(0); }
    25% { transform: translateX(-5px); }
    50% { transform: translateX(5px); }
    75% { transform: translateX(-5px); }
    100% { transform: translateX(5px); }
}

const submitBtn = document.querySelector("#submit-btn");  
const inputs = document.querySelectorAll('input[name="rating"]');

submitBtn.addEventListener("click", (event) => {
    event.preventDefault();

    let rating;
    for (const input of inputs) {
        if (input.checked) {
            rating = input.value;
            break;
        }
    }

    if (!rating) {
        submitBtn.classList.add("shake");

        setTimeout(() => {
            submitBtn.classList.remove("shake");
        }, 500);

        return;
    }

    document.getElementById("rating-state").style.display = "none";
    document.getElementById("thank-you-state").style.display = "block";
    document.getElementById("obtained-rating").innerHTML = rating;

});
