Dynamischer Fortschrittsbalken mit Farbverlauf, implementiert mit CSS3 und JQuery

Fortschrittsbalken sind eine gängige Art von Website. Nachdem ich heute das Beispiel einer ausländischen Website studiert habe, habe ich versucht, CSS3 zu verwenden, um den Fortschrittsbalken zu implementieren:

Der HTML-Code ist wie folgt:

    <div class="progress-bar blue stripes">
    <span style="width: 40%"></span>
</div>
<p>Set above to:
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
</p>
 
<div class="progress-bar orange shine">
    <span style="width: 65%"></span>
</div>
<p>Set above to:
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
</p>
 
<div class="progress-bar green glow">
    <span style="width: 55%"></span>
</div>
<p>Set above to:
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
    <a href="http://www.php1.cn/">
</p>

CSS-Stil:

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;    }

Implementieren Sie hauptsächlich den Hintergrund des Fortschrittsbalkens:
