这是我的代码

<div class="fieldlist">
    <label for="shipadd2">
    <input type="radio" id="shipadd2" name="address" />   
    <div class="compacttext"> Lorem ipsum </div>
    </label>
  </div>

CSS是

.fieldlist input[type="radio"] {
    float: right;
    -webkit-appearance: none;
    border: none;
    width: 25px;
    height: 25px;
    background: url(images/radio.png) left center no-repeat;    
    background-size: 20px; 
}
.fieldlist input[type="radio"]:checked {
    background: url(images/radio_checked.png) left center no-repeat;
 
}
