Replace jQuery DOM Manipulation with Vanilla JavaScript
Description
jQuery was great, but modern browsers support native DOM methods that are faster and cleaner. This update removes jQuery dependency.
Original Code (Outdated)
$("#message").hide();
$("#message").fadeIn(1000);
Updated Code (Modern)
const msg = document.getElementById("message");
msg.style.display = "none";
setTimeout(() => {
msg.style.display = "block";
msg.style.opacity = 1;
}, 1000);
