HTML&CSS ：数字卡片翻转效果

前端Hardy
596 阅读7分钟

这个页面实现了一个动态的数字翻转效果，用于显示分钟和秒。HTML 提供了结构，CSS 定义了样式和动画，JavaScript 则通过定时器动态更新数字，实现翻转效果。

大家复制代码时，可能会因格式转换出现错乱，导致样式失效。建议先少量复制代码进行测试，若未能解决问题，私信我，我会发送完整的压缩包给你。

HTML 结构

  • container：页面的核心容器，居中显示，包含两个翻转效果的数字列表（分钟和秒）。
  • flip minutePlay 和 flip secondPlay：分别用于显示分钟和秒的数字。每个li表示一个数字，包含两个部分：up 和 down，分别表示数字的上半部分和下半部分。每个数字的上下部分都有一个 shadow 用于显示阴影，以及一个 inn用于显示数字内容

CSS 样式

  • *：重置所有元素的外边距和内边距，并设置 box-sizing 为 border-box。
  • body：设置了背景颜色和渐变效果，定义了字体样式、颜色和阴影。
  • a 和 a:hover：定义了链接的样式，鼠标悬停时颜色变化。
  • .container：将容器居中显示，设置为绝对定位。
  • ul.flip：定义了翻转数字的容器样式，包括宽度、高度、字体大小和阴影。
  • ul.flip li：每个数字的样式，绝对定位，覆盖整个父容器。
  • ul.flip li a：为每个数字添加了 perspective（透视效果），使翻转动画更立体。
  • ul.flip li a div：定义了数字上下部分的样式，包括 transform-origin（旋转轴）。
  • ul.flip li a div.up 和 ul.flip li a div.down：分别定义了数字的上半部分和下半部分的样式。
  • ul.flip li a div div.inn：定义了数字内容的样式，包括背景颜色、圆角和阴影。
  • @keyframes asd：定义了数字翻转时的层级变化。
  • @keyframes turn 和 @keyframes turn2：定义了数字上下部分的翻转动画。
  • @keyframes show 和 @keyframes hide：定义了阴影的显示和隐藏动画。

JavaScript部分

secondPlay() 和 minutePlay()

  • 这两个函数分别用于更新秒和分钟的值。
  • 每次调用时，会移除当前激活的数字（active 类），并将其设置为“之前”状态（before 类）。
  • 然后将下一个数字设置为激活状态（active 类），并触发翻转动画。
  • 如果当前数字是最后一个，会循环回到第一个数字。

setInterval

  • 每秒调用一次 secondPlay()，每 10 秒调用一次 minutePlay()，实现动态更新。
