<style>  .gn_box{     border: none;     border-radius: 15px; }  .gn_box {     padding: 10px 14px;     margin: 10px;     margin-bottom: 20px;     text-align: center;     background-color: #fff; }  #t_d{     color: #982585;     font-size: 18px; }  #t_h{     color: #8f79c1;     font-size: 18px; }  #t_m{     color: #65b4b5;     font-size: 18px; }  #t_s{     color: #83caa3;     font-size: 18px; }  </style>  <div class="gn_box">      <h1><font color=#E80017>2</font><font color=#D1002E>0</font><font color=#BA0045>2</font><font color=#A3005C>3</font><font  color=#8C0073>年</font><font color=#75008A>-</font> <font color=#5E00A1>新</font><font color=#4700B8>年</font><font color=#3000CF>倒</font><font color=#1900E6>计</font><font color=#0200FD>时</font></h1><center> <div id="CountMsg" class="HotDate"><span id="t_d"> 天</span><span id="t_h"> 时</span><span id="t_m"> 分</span><span id="t_s"> 秒</span></div></center> <script type="text/javascript">  function getRTime() {        var EndTime = new Date('2023/01/22 00:00:00');       var NowTime = new Date();       var t = EndTime.getTime() - NowTime.getTime();              var d = Math.floor(t / 1000 / 60 / 60 / 24);              var h = Math.floor(t / 1000 / 60 / 60 % 24);              var m = Math.floor(t / 1000 / 60 % 60);              var s = Math.floor(t / 1000 % 60);      var day = document.getElementById("t_d");     if (day != null) {         day.innerHTML = d + " 天";        }     var hour = document.getElementById("t_h");     if (hour != null) {         hour.innerHTML = h + " 时";       }     var min = document.getElementById("t_m");     if (min != null) {         min.innerHTML = m + " 分";        }     var sec = document.getElementById("t_s");     if (sec != null) {         sec.innerHTML = s + " 秒";     } }      setInterval(getRTime, 1000);      </script> </div>

注意事项

关于如何更改目标时间，在代码内找到var EndTime = new Date('2022/01/1 00:00:00');修改里面时间即可

修改显示信息

代码里面都可以看到 大家自己看看
