这个DEMO是使用CSS3制作的一个分步注册表单，每个input对应的是每一步，在表单得到焦点时，对应的step也会进行对应的改变。不过这个效果是使用js代码来实现，但整个表单的外观是由CSS3来完成的，整个案例中使用了：@font-face来制作icon图标，使用gradient来制作渐变的按钮效果，使用text-shadow来制作文字阴影效果等等，方便简单点，但细节与创意才是最重要的，喜欢的同学可以看看是怎么实现的吧。

JavaScript代码
window.onload=function(){
var oForm=document.getElementById('form-control');
var aLabel=oForm.getElementsByTagName('label');
var aInput=oForm.getElementsByTagName('input')
for(var i=0;i<aLabel.length;i++){
aInput[i].index=i;
aLabel[i].onclick=function(){
for(var i=0;i<aLabel.length;i++){
aLabel[i].className='';
}
this.className='active';
}
aInput[i].onclick=function(){
for(var i=0;i<aLabel.length;i++){
aLabel[i].className='';
}
aLabel[this.index].className='active';
}
}
}
其实当前Step的状态可以使用“:target”来制作，有兴趣的同学不仿一试。
