JavaScript Date() 对象:
new Date() :时间对象,会把当前时间作为其初始值;
setFullYear() :用于设置月份,可有三个参数,setFullYear(year,month,day);
setHours() :设置指定时间的小时,可有四个参数,setHours(hour,min,sec,millisec);
getDate() :返回月份的某一天;
getMonth() :返回表示月份的数字;
getFullYear() :返回一个表示年份的 4 位数字;
getTime() :返回距 1970 年 1 月 1 日之间的毫秒数;
setFullYear() :设置年份;
setDate() :设置日;

不用安装到本地,直接引用外部字体文件
@font-face{
font-family: "Digital-7 Mono";
src: url('Digital-7Mono.TTF');
}
URL 是文件的路径
