    border-top: 8px solid #3498db; /* Blue color */
    border-radius: 50%; /* Circle */
    width: 60px; /* Size */
    height: 60px; /* Size */
    animation: spin 2s linear infinite; /* Spin animation */
}

@keyframes spin {
    0% { transform: rotate(0deg); }
    100% { transform: rotate(360deg); }
}
