- 使用
伪元素和元素的颜色差，让伪元素向我们的方向移动，实现影子效果。 - 使用
transform属性，计算每一个块元素的位置组成一个数字。
添加数字变换动画
... .number[data-digit="1"] .line:nth-child(1)::before, .number[data-digit="1"] .line:nth-child(1)::after, .number[data-digit="1"] .line:nth-child(2)::before, .number[data-digit="1"] .line:nth-child(2)::after, .number[data-digit="1"] .line:nth-child(3)::before, .number[data-digit="1"] .line:nth-child(3)::after, .number[data-digit="1"] .line:nth-child(4)::before, .number[data-digit="1"] .line:nth-child(4)::after, .number[data-digit="1"] .line:nth-child(6)::before, .number[data-digit="1"] .line:nth-child(6)::after, .number[data-digit="2"] .line:nth-child(4)::before, .number[data-digit="2"] .line:nth-child(4)::after, .number[data-digit="2"] .line:nth-child(7)::before, .number[data-digit="2"] .line:nth-child(7)::after, .number[data-digit="3"] .line:nth-child(4)::before, .number[data-digit="3"] .line:nth-child(4)::after, .number[data-digit="3"] .line:nth-child(6)::before, .number[data-digit="3"] .line:nth-child(6)::after, .number[data-digit="4"] .line:nth-child(1)::before, .number[data-digit="4"] .line:nth-child(1)::after, .number[data-digit="4"] .line:nth-child(3)::before, .number[data-digit="4"] .line:nth-child(3)::after, .number[data-digit="4"] .line:nth-child(6)::before, .number[data-digit="4"] .line:nth-child(6)::after, .number[data-digit="5"] .line:nth-child(5)::before, .number[data-digit="5"] .line:nth-child(5)::after, .number[data-digit="5"] .line:nth-child(6)::before, .number[data-digit="5"] .line:nth-child(6)::after, .number[data-digit="6"] .line:nth-child(5)::before, .number[data-digit="6"] .line:nth-child(5)::after, .number[data-digit="7"] .line:nth-child(2)::before, .number[data-digit="7"] .line:nth-child(2)::after, .number[data-digit="7"] .line:nth-child(3)::before, .number[data-digit="7"] .line:nth-child(3)::after, .number[data-digit="7"] .line:nth-child(4)::before, .number[data-digit="7"] .line:nth-child(4)::after, .number[data-digit="7"] .line:nth-child(6)::before, .number[data-digit="7"] .line:nth-child(6)::after, .number[data-digit="9"] .line:nth-child(6)::before, .number[data-digit="9"] .line:nth-child(6)::after, .number[data-digit="0"] .line:nth-child(2)::before, .number[data-digit="0"] .line:nth-child(2)::after { transform: translateZ(25px); background: #3c4444; box-shadow: 0 0 1vw #425454; } ... <script type="text/javascript"> (function () { let numbers = document.getElementsByClassName("number") setInterval(() => { Array.prototype.slice.call(numbers).forEach((key) => { key.setAttribute("data-digit",parseInt(Math.random() * 9)); }); }, 1000); })() </script>...复制代码- 使用
transition属性给line::before和line::after设置过度动画。 - 通过css属性选择器，获取自定义属性的值。通过变换的值来设置在不同数字下，哪些块需要改变。
- 使用
js修改自定义属性的值。
加入时间

- 使用js获取当前时间，依次修改自定义变量的值。
