HTML+CSS制作一个高考倒计时

起因

最近听到要开学的消息，就会想到考试，提到考试自然就会想到受本次疫情影响的高考考生。最后琢磨着做一个高考倒计时网页。为了时间长一点，我特地把日期调为了2021年的高考(别问我，我也不知道我是怎么想的)。然后呢。。。我并不会html/css(因为学业繁忙)，于是就跟着B站制作新年倒计时网页的视频抄了抄代码,勉强搞出来了。

代码

html代码

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <title>Countdown to NCEE</title>
        <link rel="stylesheet" href="css/style.css">
    </head>
    <body>
         <div class="container">
             <h2><span>Countdown to NCEE</span> 2021</h2>
             <div class="countdown">
                 <div id="day">NA</div>
                 <div id="hour">NA</div>
                 <div id="minute">NA</div>
                 <div id="second">NA</div>
             </div>
         </div>
         <script type="text/javascript">
             var countDate = new Date('June 7, 2021 00:00:00').getTime();
             
             function nceetime(){
                 var now = new Date().getTime();
                 gap = countDate - now;
                 
                 var second = 1000;
                 var minute = second * 60;
                 var hour = minute * 60;
                 var day = hour * 24;
                 
                 var d = Math.floor(gap / (day));
                 var h = Math.floor(gap % (day) / (hour));
                 var m = Math.floor(gap % (hour) / (minute));
                 var s = Math.floor(gap % (minute) / second);
                 
                 document.getElementById('day').innerText = d;
                 document.getElementById('hour').innerText = h;
                 document.getElementById('minute').innerText = m;
                 document.getElementById('second').innerText = s;
             }
             
             setInterval(function(){
                 nceetime();
             },1000)
         </script>
    </body>
