这次给大家带来html+js实现滚动数字的时钟，html+js实现滚动数字时钟的注意事项有哪些，下面就是实战案例，一起来看一下。
下面就是这个滚动时钟动画的全部代码：

<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() {

}
var loop = setinterval(function () {

columns.foreach(function (ele, i) {
var n = +c[i];
var offset = -n * size;
ele.style.transform = 'translatey(calc(50vh + ' + offset + 'px - ' + size / 2 + 'px))';

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。
