Practical example:

    var headStyle = 'text-shadow: 0px 0px 4px #ff0; font-weight: 700; font-size: 50px; color: red';
    var textStyle = 'font-weight: 700; font-size: 16px; color: blue';
    var warningStyle = 'font-weight: 700; font-size: 20px; color: red';

    console.log(
       '\n' +
       '%cStop!\n' +
       '%cThis feature is created only for software developers.\n' +
       '%cIf someone asked you to copy, paste or do something here don\'t do it!\n\n' +
       '%cIt can be dangerous and can lead to HACKs on your account!\n\n',
       headStyle, textStyle, textStyle, warningStyle
