像这样

    border: 2px solid black;
    padding-top: 1px;
}
.slideon {
    height: 21px;
    margin: 2px;
}
#slideshow { 
    margin: 50px auto; 
    position: relative; 
    width: 240px; 
    height: 240px; 
    padding: 10px;

这里是如何做到这一点的简单例子。

只需替换图像文件，你就完成了。

<input type="radio" id="r1" name="rr" />
<label for="r1"><span></span>Radio Button 1</label>
<p>
<input type="radio" id="r2" name="rr" />
<label for="r2"><span></span>Radio Button 2</label>

input[type="radio"] {
    display:none;
}
input[type="radio"] + label {
    color:#f2f2f2;
    font-family:Arial, sans-serif;
    font-size:14px;
}
input[type="radio"] + label span {
    display:inline-block;
    width:19px;
    height:19px;
    margin:-1px 4px 0 0;
    vertical-align:middle;
    background:url(check_radio_sheet.png) -38px top no-repeat;
    cursor:pointer;
}
input[type="radio"]:checked + label span {
    background:url(check_radio_sheet.png) -57px top no-repeat;
}

您应该使用一些背景图像到您的单选按钮，并翻转它与另一个图像的变化

.radio {
    background: url(customButton.png) no-repeat;
}

<input type="radio" id="radio-2-1" name="radio-2-set" cl="regular-radio" /><label for="radio-2-1"></label>
<input type="radio" id="radio-2-2" name="radio-2-set" cl="regular-radio" /><label for="radio-2-2"></label>
<input type="radio" id="radio-2-3" name="radio-2-set" cl="regular-radio" /><label for="radio-2-3"></label>
.regular-radio {
    display: none;
}
.regular-radio + label {
    -webkit-appearance: none;
    background-color: #e1e1e1;
    border: 4px solid #e1e1e1;
    border-radius: 10px;
    width: 100%;
    display: inline-block;
    position: relative;
    width: 10px;
    height: 10px;
}
.regular-radio:checked + label {
    background: grey;
    border: 4px solid #e1e1e1;
}
