用css3和jquery实现的渐变的动态进度条
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：
<div class="progress-bar blue stripes">
<span style="width: 40%"></span>
</div>
<p>Set above to:
<a href="#" class="quarter">25%</a> /
<a href="#" class="half">50%</a> /
<a href="#" class="three-quarters">75%</a> /
<a href="#" class="full">100%</a>
</p>
<div class="progress-bar orange shine">
<span style="width: 65%"></span>
</div>
<p>Set above to:
<a href="#" class="quarter">25%</a> /
<a href="#" class="half">50%</a> /
<a href="#" class="three-quarters">75%</a> /
<a href="#" class="full">100%</a>
</p>
<div class="progress-bar green glow">
<span style="width: 55%"></span>
</div>
<p>Set above to:
<a href="#" class="quarter">25%</a> /
<a href="#" class="half">50%</a> /
<a href="#" class="three-quarters">75%</a> /
<a href="#" class="full">100%</a>
</p>
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：
.blue span {
background-color: #34c2e3;
}
.orange span{

-ms-filter: "progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr='#fecf23', endColorstr='#fd9215')"; /* IE8 */
}
.green span{

to(transparent));
background-image: -webkit-linear-gradient(135deg, rgba(255, 255, 255, .15) 25%, transparent 25%,
transparent 50%, rgba(255, 255, 255, .15) 50%, rgba(255, 255, 255, .15) 75%,
transparent 75%, transparent);
background-image: -moz-linear-gradient(135deg, rgba(255, 255, 255, .15) 25%, tr
