css3和jquery实现自定义checkbox和radiobox组件

主要思路是利用隐藏原来的checkbox和radiobox，用一个div来模拟checkbox/radiobox，并使用jQuery来完成选择切换时的动画效果。

代码如下:
<ul>
<li>
<p>Gender:</p>
</li>
<li>
<input type="radio" name="radio-btn" />Male</li>
<li>
<input type="radio" name="radio-btn" />Female</li>
</ul>
<ul>
<li>
<p>Favorite music:</p>
</li>
<li>
<input type="checkbox" name="check-box" /> <span>Pop music</span></p> <p> </li>
<li>
<input type="checkbox" name="check-box" /> <span>Rock music</span></p> <p> </li>
<li>
<input type="checkbox" name="check-box" /> <span>Rap music</span></p> <p> </li>
<li>
<input type="checkbox" name="check-box" /> <span>Hiphop music</span></p> <p> </li>
</ul>

然后我们用jQuery代码来为每一个checkbox和radiobox创建一个div，这个div的classname为check-box和radio-btn。

代码如下:
$('input[name="radio-btn"]').wrap('<div class="radio-btn"><i></i></div>');
$('input[name="check-box"]').wrap('<div class="check-box"><i></i></div>');

那么我们接下来要让原来的checkbox隐藏，同时设置模拟div的样式：

代码如下:
.radio-btn input[type="radio"], .check-box input[type="checkbox"] {
visibility: hidden;
}

代码如下:
.check-box {
width: 22px;
height: 22px;
cursor: pointer;
display: inline-block;
margin: 2px 7px 0 0;
position: relative;
overflow: hidden;

}
.checkedBox {
-moz-box-shadow: inset 0 0 5px 1px #ccc;
