时间是非常有限的，过去时光永远不会再回来。要在有限的时间里面，去面对生活的困难和生存的竞争，是需要强化自我的。而这些强化学习是最需时间的。而人的精力又是非常有限的，能用来做有意义的时间少之又少。所以充分利用好有限的时间，才能面对生活的困难和压力。

源码部分讲解

配置设计

var config={    'language_type':2,    'font_color':'#dce0f6',    'pointer_color':'#09f5ea',    'sound':0,    'sound_name':'bg.mp3',    'background_style':1,    'background_picture':'bg.jpg',    'background_video':'3.mp4',    'background_color':'#000000',}

旋转功能设计

 setTimeout(function () {        $(".year span").css("animation","yearRun 1s linear infinite");        style.insertRule("@keyframes yearRun {0%{transform: rotateZ(0);transform-origin: -"+yearLeft+" "+top+";}100%{transform:rotateZ(720deg);transform-origin: -"+yearLeft+" "+top+";}}",style.rules.length);        $($(".main-content .second span")[0]).removeClass("current");        $(".second span").each(function(index,element){            $(element).css("animation","secondRun"+index+" 1s linear infinite");            style.insertRule("@keyframes secondRun"+index+" {0%{transform: rotateZ(0);transform-origin: -"+secondLeft+" "+top+";}100%{transform:rotateZ("+((index+1)*720)+"deg);transform-origin: -"+secondLeft+" "+top+";}}",style.rules.length);        });        $($(".main-content .minute span")[0]).removeClass("current");        $(".minute span").each(function(index,element){            $(element).css("animation","minuteRun"+index+" 1s linear infinite");            style.insertRule("@keyframes minuteRun"+index+" {0%{transform: rotateZ(0);transform-origin: -"+minuteLeft+" "+top+";}100%{transform:rotateZ("+((index+1)*720)+"deg);transform-origin: -"+minuteLeft+" "+top+";}}",style.rules.length);        });        $($(".main-content .hour span")[0]).removeClass("current");        $(".hour span").each(function(index,element){            $(element).css("animation","hourRun"+index+" 1s linear infinite");            style.insertRule("@keyframes hourRun"+index+" {0%{transform: rotateZ(0);transform-origin: -"+hourLeft+" "+top+";}100%{transform:rotateZ("+((index+1)*720)+"deg);transform-origin: -"+hourLeft+" "+top+";}}",style.rules.length);        });        $($(".main-content .shichen span")[0]).removeClass("current");        $(".shichen span").each(function(index,element){            $(element).css("animation","shichenRun"+index+" 1s linear infinite");            style.insertRule("@keyframes shichenRun"+index+" {0%{transform: rotateZ(0);transform-origin: -"+shichenLeft+" "+top+";}100%{transform:rotateZ("+((index+1)*720)+"deg);transform-origin: -"+shichenLeft+" "+top+";}}",style.rules.length);        });        $($(".main-content .week span")[0]).removeClass("current");        $(".week span").each(function(index,element){            $(element).css("animation","weekRun"+index+" 1s linear infinite");            style.insertRule("@keyframes weekRun"+index+" {0%{transform: rotateZ(0);transform-origin: -"+weekLeft+" "+top+";}100%{transform:rotateZ("+((index+1)*720)+"deg);transform-origin: -"+weekLeft+" "+top+";}}",style.rules.length);        });        $($(".main-content .day span")[0]).removeClass("current");        $(".day span").each(function(index,element){            $(element).css("animation","dayRun"+index+" 1s linear infinite");            style.insertRule("@keyframes dayRun"+index+" {0%{transform: rotateZ(0);transform-origin: -"+dayLeft+" "+top+";}100%{transform:rotateZ("+((index+1)*720)+"deg);transform-origin: -"+dayLeft+" "+top+";}}",style.rules.length);        });        $($(".main-content .month span")[0]).removeClass("current");        $(".month span").each(function(index,element){            $(element).css("animation","monthRun"+index+" 1s linear infinite");            style.insertRule("@keyframes monthRun"+index+" {0%{transform: rotateZ(0);transform-origin: -"+monthLeft+" "+top+";}100%{transform:rotateZ("+((index+1)*720)+"deg);transform-origin: -"+monthLeft+" "+top+";}}",style.rules.length);        });    }, 7000);

更新每日

至于每秒每小时都差不多

 $(".day").html("");            Time.days=updateDays(type,year,month,1);            Time.currentTime.day=getFirstDay(type);            $(".main-content .day").append("<span class='current'>"+Time.currentTime.day+Time.dayUnit+"</span>");            for (const key in Time.days) {                if (Time.days.hasOwnProperty(key)) {                    const element = Time.days[key];                    if(element!=Time.currentTime.day){                        $(".main-content .day").append("<span>"+element+Time.dayUnit+"</span>");                    }                }            }            $(".day span").each(function(index,element){                $(element).css("animation","day"+index+" 0.5s linear");                $(element).css("animation-fill-mode","forwards");                style.insertRule("@keyframes day"+index+"{0%{transform: rotateZ(0);transform-origin: -"+dayLeft+" "+top+";}100%{transform:rotateZ("+-(360/Time.days.length)*(index+1)+"deg);transform-origin: -"+dayLeft+" "+top+";}}",style.rules.length);            });
