如何在浏览器控制台(console)里输出彩色样式调试信息

console.log(XX,XX,XX)

　　log 的第一个参数声明第二、第三个参数的作用，第二个参数就是样式，第三个参数是要输出的字符串

console.log("%c%s",
            "color: green; font-size: 100px;font-weight:bolder",
            "ABC");

　　

 console.log('\n  ██████\n  ██    ██\n  ██    ██\n  ██    ██    ████\n  ██████    ██    ██\n  ██    ██  ████████\n  ██    ██  ██\n  ██    ██    ████\n\n');
