最近才开始写博客,所以把前几个月做项目时遇到的问题整理一下写出来,众所周知,表单中的一写元素原生样式不是很好看,项目中用到的时候需要优化,今天我就写一下单选按钮很多选按钮的样式的优化,首先自己要做出按钮选中之前的图片和按钮选中之后的图片。然后就是代码了。直接上代码:(代码比较多,这是我之前在做项目时样式都搬过来了,样式什么都是可以自己写的。)

HTML代码结构如下:<br /><br /> 1 <div class="radio" >  2     <label> 3         <input type="radio" name="sex" value="" /> 4         <div class="option"></div><!--该div盛放的是优化后的按钮图片--> 5         <span class="opt-text">男</span> 6     </label> 7 </div> 8 <div class="radio"> 9     <label>10         <input type="radio" name="sex" value="" />11         <div class="option"></div><!--该div盛放的是优化后的按钮图片-->12         <span class="opt-text">女</span>13     </label>14 </div>

css代码如下:<br /><br /> 1 label {                 /*设置label的样式*/ 2     width: 100%; 3     padding: 10px 0px; 4     display: block; 5     line-height: 20px; 6     position: relative; 7     font-weight: normal; 8 } 9 .radio .option {      /*把优化后的按钮图片设置为该div的背景图片,把该div定位到原生样式的上方,遮盖住原生样式。*/10     width: 25px;11     height: 25px;12     position: absolute;13     top: 10px;14     left: 0px;15     background-size: cover;16     background: url(img/radio.png) no-repeat;17     background-size: cover;18 }19 .radio input[type="radio"] {  /*为了保险起见,把原生样式隐藏掉*/20     display: inline-block ;21     margin-right: 15px ;22     opacity: 0 ;23 }24 input[type="radio"]:checked+div {  /*当radiuo被选中时,把input下边的div标签的背景图片替换掉*/25     background: url(img/radio-checked.png) no-repeat;26     background-size: cover;27 }
