进度条是网站中常见的一种，今天经过研究外国一个网站的例子，试着用css3来实现进度条：
html代码如下：
Set above to:
25% /
50% /
75% /
100%
Set above to:
25% /
50% /
75% /
100%
Set above to:
25% /
50% /
75% /
100%
css样式：
body{ background:#222; width:360px; margin:0 auto; font:13px 'trebuchet MS',Arial,Helvetica;}
h2, p {text-align: center;color: #fafafa;text-shadow: 0 1px 0 #111; }
a {color: #777;}
.progress-bar{ background-color:#1a1a1a; height:25px; padding:5px; width:350px; margin:70px 0 20px 0;-moz-border-radius:5px; -webkit-border-raidus:5px; border-radius:5px;-moz-box-shadow:0 1px 5px #000 inset, 0 1px 0 #444;-webkit-box-shadow:0 1px 5px #1a1a1a inset,0 1px 0 #444; box-shadow:0 1px 5px inset,0 1px 0 #444; }
.progress-bar span{ display:inline-block; height:100%; background-color:#777; -moz-border-radius:3px;-webkit-border-radius:3px; border-radius:3px; border-radius:3px; box-shadow:0 1px 0 rgba(255,255,255,.5) inset; -webkit-box-shadow:0 1px 0 rgba(255,255,.5) inset; -moz-box-shadow:0 1px 0 rgba(255,255,.5) inset; -webkit-transition:width .4s ease-in-out; -moz-transition:width .4s ease-in-out;-ms-transition:width .4s ease-in-out;transition: width .4s ease-in-out; }
主要实现进度条的背景：

预览效果：
jquey部分：
$(document).ready(function(){
$('.quarter').click(function(){
$(this).parent().prev().children("span").css('width','25%');
});
$('.half').click(function(){
$(this).parent().prev().children('span').css("width",'50%');
});
$('.three-quarters').click(function(){
$(this).parent().prev().children('span').css('width','75%');
});
$('.full').click(function(){
$(this).parent().prev().children('span').css('width','100%');
