How to get the Apple Javascript Split Flap Counter to run on pure CSS
How can I replicate apple's split flap counter without using the filmstrip image? I would like开发者_JS百科 to create something similar displaying words and other special characters.
Maybe using CSS transitions or css transforms?

Thanks.
I've implemented this using DIVs, setInterval, setTimeout and CSS3 (webkit-transform, animation, and keyframes).
Here's the rough code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<style>
@-webkit-keyframes spin {
0% { -webkit-transform-origin: 100% 100%; -webkit-transform: rotateX(0deg) skew(0deg, 0deg); }
100% { -webkit-transform-origin: 100% 100%; -webkit-transform: rotateX(90deg) skew(5deg, 0deg); }
}
@-webkit-keyframes spin2 {
0% { -webkit-transform-origin: 0% 0%; -webkit-transform: rotateX(90deg) skew(-5deg, 0deg); }
100% { -webkit-transform-origin: 0% 0%; -webkit-transform: rotateX(0deg) skew(0deg, 0deg); }
}
.box span { font-family: arial; font-weight:bold; font-size: 72px; display:inline-block; }
.scale { -webkit-animation: spin 0.15s infinite linear; }
.scale2 { -webkit-animation: spin2 0.15s infinite linear; }
.dv { background-color: #FFF; border:1px solid #333; display:block; height:45px; width:80px; overflow:hidden; text-align: center; line-height:100%; }
.dv > div > span { width:100%; vertical-align:middle }
.dv > div { height:200%; }
.down > div { position:relative; top:-100%; }
.spn { position:absolute; }
.spn.top { z-index:20 }
.spn.top > .dv { z-index:15 }
.spn.down { z-index:10 }
.spn.down > .dv { z-index:5 }
</style>

While not in pure CSS, someone has built a nice script to exactly replicate the functionality from Apple's site.
