    username.trim().length !== 0 ||
    email.trim().length !== 0 ||
    password.trim().length !== 0 ||
    confirmpassword.trim().length !== 0
  ) {
    return true;
  } else {
    
    msgPassword.style.border = "2px solid red";
    msgConfirm.style.border = "2px solid red";
    document.getElementById("error-allength").innerHTML =
