css3和图片分别实现checkbox单选和多选效果

1.css3实现模拟checkbox效果

<style>
.checkbox {
    position: relative;
    height: 30px;
}
.checkbox input[type='checkbox'] {
    position: absolute;
    left: 0;
    top: 0;
    width: 20px;
    height: 20px;
    opacity: 0;
}
.checkbox label {
    position: absolute;
    left: 30px;
    top: 0;
    height: 20px;
    line-height: 20px;
}
.checkbox label:before {
    content: '';
    position: absolute;
    left: -30px;
    top: 0;
    width: 20px;
    height: 20px;
    border: 1px solid #ddd;
    border-radius: 50%;
    transition: all 0.3s ease;
    -webkit-transition: all 0.3s ease;
    -moz-transition: all 0.3s ease;
}

.checkbox label:after {
    content: '';
    position: absolute;
    left: -22px;
    top: 3px;
    width: 6px;
    height: 12px;
    border: 0;
    border-right: 1px solid #fff;
    border-bottom: 1px solid #fff;
    background: #fff;
    transform: rotate(45deg);
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    transition: all 0.3s ease;
    -webkit-transition: all 0.3s ease;
    -moz-transition: all 0.3s ease;
}

.checkbox input[type='checkbox']:checked + label:before {
    background: #4cd764;
    border-color: #4cd764;
}
.checkbox input[type='checkbox']:checked + label:after {
    background: #4cd764;
}
</style>

在使用的时候使用下面的html代码

<div class='checkbox'>
    <input type='checkbox' id='checkbox1' name='checkboox[]'>
    <label for='checkbox1'>篮球</label>
</div>
<div class='checkbox'>
    <input type='checkbox' id='checkbox2' name='checkboox[]'>
    <label for='checkbox2'>乒乓球</label>
</div>
<div class='checkbox'>
    <input type='checkbox' id='checkbox3' name='checkboox[]' checked>
    <label for='checkbox3'>足球</label>
</div>

2.图片实现

扩展jquery插件

(function($){
	$.extend({
		inputStyle:function(){
			function check(el,cl){
				$(el).each(function(){
					$(this).parent('i').removeClass(cl);

					var checked = $(this).prop('checked');
					if(checked){
						$(this).parent('i').addClass(cl);
					}
				})
			}	
			$('input[type="radio"]').on('click',function(){
				check('input[type="radio"]','radio_bg_check');
			})
			$('input[type="checkbox"]').on('click',function(){
				check('input[type="checkbox"]','checkbox_bg_check');
			})
		}
		
	})

})(jQuery)

//调用
$(function(){
	$.inputStyle();
})

css样式：

@charset 'utf-8';
*{
	padding: 0;
	margin-left: 0;
}
input[type='radio'],input[type='checkbox']{
	width: 20px;
	height: 20px;
	vertical-align:middle;
	opacity: 0;

}
.input_style{
	background: url(../img/green.png) no-repeat;
	width: 20px;
	height: 20px;
	display: inline-block;
}
.radio_bg{
	background-position: -118px 0 ;
}
.checkbox_bg{
	background-position: 0 0;
}
.radio_bg_check{
	background-position: -166px 0 ;
}
.checkbox_bg_check{
	background-position: -48px 0;
}

前端页面

	<p>

			<i class='input_style radio_bg'><input type="radio" name="hot" value="1"></i>
