先看看效果

Step 1: XHTML

 <ul class="star-rating">  
    <li><a href="#" title="Rate this 1 star out of 5" class="one-star">1</a></li>   
    <li><a href="#" title="Rate this 2 stars out of 5" class="two-stars">2</a></li>  
    <li><a href="#" title="Rate this 3 stars out of 5" class="three-stars">3</a></li>  
    <li><a href="#" title="Rate this 4 stars out of 5" class="four-stars">4</a></li> 
    <li><a href="#" title="Rate this 5 stars out of 5" class="five-stars">5</a></li>
 </ul>

这里只介绍静态的技术，随后会给出系统的应用，你也是自己加程序来尝试一下，还可以采用ajax来做出绚丽的效果

Step 2:图像|Graphics

为了节省您的空间和宽带，我们采用gif图，这个图片就是打分的按钮。

Step 3:CSS

    .star-rating{
    list-style: none; /* turn off the default list image bullets*/
    margin: 3px; /*I wan’t some space around this thing*/
    padding: 0px; /* I’m anal. I’m pretty sure OL’s have a default padding of 0px, but we’ll set it to 0px just to be safe*/
    width: 100px; /*This list is 5 stars, each star is 20px, therefore it should be 5 x 20px = 100px wide*/
    height: 20px; /* The height of each star is 20px. Since this is a horizontal list, we will set the list height to the height of the star.*/
    position: relative; /*Very important. We will be using absolute positioning later. We want to use relatively-absolute positioning.*/
    background: url(star_rating.gif) top left repeat-x; /* By repeating this image horizontally, the list will appear to have five stars.*/
    }

根据代码我们知道：
去掉了ul的margin和padding以及list-style，定义了高20px宽100px的一个区块

下来时按钮元素的制作，下面是css

    .star-rating li{
    padding:0px; /* no padding at all*/
    margin:0px; /* no margin at all*/
    /*\*/ /*Backslash hack, this causes IE5 Mac NOT to see this rule*/
    float: left; /* for any other browser, we are going to float left, this makes a horizontal list*/
    /* */ /* end the IE5 Backslash hack*/
    }

这段代码让li实现横向排放，并解决IE5 MAC bug
