<script>
'use strict';
var size = 86;
var columns = Array.from(document.getElementsByClassName('column'));
var d = undefined,
 c = undefined;
var classList = ['visible', 'close', 'far', 'far', 'distant', 'distant'];
var use24HourClock = true;
function padClock(p, n) {
return p + ('0' + n).slice(-2);
}
function getClock() {
d = new Date();
return [use24HourClock ? d.getHours() : d.getHours() % 12 || 12, d.getMinutes(), d.getSeconds()].reduce(padClock, '');
}
function getClass(n, i2) {
return classList.find(function (class_, classIndex) {
return i2 - classIndex === n || i2 + classIndex === n;
}) || '';
}
var loop = setInterval(function () {
c = getClock();
columns.forEach(function (ele, i) {
var n = +c[i];
var offset = -n * size;
ele.style.transform = 'translateY(calc(50vh + ' + offset + 'px - ' + size / 2 + 'px))';
Array.from(ele.children).forEach(function (ele2, i2) {
ele2.className = 'num ' + getClass(n, i2);
});
});
}, 200 + Math.E * 10);
</script>
</body>
</html>

注意：其中最上面的是CSS样式内容，大家可以在其中进行调整颜色字体等

<style>
body{text-align: center;background-color: #0e141b;color: rgba(224, 230, 235, 0.89);font-family: 'Roboto Condensed', sans-serif;font-weight: 300;overflow: hidden;}
.column,.colon{display: inline-block;vertical-align: top;font-size: 86px;line-height: 86px;}
.column{-webkit-transition: -webkit-transform 300ms;transition: -webkit-transform 300ms;transition: transform 300ms;transition: transform 300ms, -webkit-transform 300ms;}
.colon{-webkit-transition: -webkit-transform 300ms;transition: -webkit-transform 300ms;transition: transform 300ms;transition: transform 300ms, -webkit-transform 300ms;-webkit-transform: translateY(calc(50vh - 43px));transform: translateY(calc(50vh - 43px));}
.colon:after{content: ':';}
.num{-webkit-transition: opacity 500ms, text-shadow 100ms;transition: opacity 500ms, text-shadow 100ms;opacity: 0.025;}
.num.visible{opacity: 1.0;text-shadow: 1px 1px 0px #336699;}
.num.close{opacity: 0.35;}
.num.far{opacity: 0.15;}
.num.distant{opacity: 0.1;}
</style>

JS代码主要就是控制动画的滚动效果，CSS用来控制数字的大小等内容。
