Style it however you like, but I’ll keep it simple

$('.hastip').tooltipsy({
    css: {
        'padding': '10px',
        'max-width': '200px',
        'color': '#303030',
        'background-color': '#f5f5b5',
        'border': '1px solid #deca7e',
        '-moz-box-shadow': '0 0 10px rgba(0, 0, 0, .5)',
        '-webkit-box-shadow': '0 0 10px rgba(0, 0, 0, .5)',
