实现起来很灵活，代码如下：
<style>
.star span{
font-size: 2em;
cursor: pointer;
}
.star .red{
color: red;
}
</style>
<h3>示例1：</h3>
<div class="star exp1">
<span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span>
<i></i>
<input type="hidden" name="star" value="1">
</div>
<div class="star exp6">
<span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span>
<i></i>
<input type="hidden" name="star" value="3">
</div>
<div class="star exp4">
<span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span>
<i></i>
<input type="hidden" name="star" value="5">
</div>
<div class="star exp5">
<span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span><span>★</span>
<i></i>
<input type="hidden" name="star" value="7">
</div>
<h3>示例2：</h3>
<div class="star exp2">
<span>W</span><span>W</span><span>W</span><span>.</span><span>E</span><span>B</span><span>C</span><span>M</span><span>S</span><span>.</span><span>C</span><span>O</span><span>M</span>
<i></i>
<input type="hidden" name="star" value="3">
</div>
<h3>示例3：</h3>
<div class="star exp3">
<span>易</span><span>贝</span><span>内</span><span>容</span><span>管</span><span>理</span><span>系</span><span>统</span><span>，</span><span>基</span><span>于</span><span>T</span><span>P</span><span>5</span><span>开</span><span>发</span><span>！</span>
