效果图：
是不是比默认的好看多了，个人的审美观应该还是可以的。
当然我们可以在这里查看DEMO演示。
接下来我们一起来看看实现这款美化版Checkbox的源代码。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。
先来看看HTML代码：
<div class="wrapper">
<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>推荐网站:</p>
</li>
<li>
<input type="checkbox" name="check-box" /> <span>何问起</span> </li>
<li>
<input type="checkbox" name="check-box" /> <span>柯乐义</span> </li>
<li>
<input type="checkbox" name="check-box" /> <span>hwq2.com</span> </li>
<li>
<input type="checkbox" name="check-box" /> <span>hovertree.net</span> </li>
</ul>
</div>
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。
$("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：
.radio-btn input[type="radio"], .check-box input[type="checkbox"] {
visibility: hidden;
}
.check-box {
width: 22px;
height: 22px;

上面这段CSS3代码就是用样式来自定义div，让div的样式和checkbox和radiobox一样。
最后我们来模拟点击选中和取消选中，这部分也是用jQuery来实现：
$(".radio-btn").on("click", function () {
var _this = $(this),
block = _this.parent().parent();
block.find("input:radio").attr("checked", false);
block.find(".radio-btn").removeClass("checkedRadio");
_this.addClass("checkedRadio");
_this.find("input:radio").attr("checked", true);
});
$.fn.toggleCheckbox = function () {
this.attr("checked", !this.attr("checked"));
}
$(".check-box").on("click", function () {
$(this).find(":checkbox").toggleCheckbox();
$(this).toggleClass("checkedBox");
});/* 何问起 hovertree.com */
