javascript - 自定义 HTML 中的单选按钮并删除可检查的圆圈

Question

我有一个问题，有没有办法自定义单选按钮并使用可检查卡而不是可检查圆圈？

我正在研究多项选择题，需要它来使问题视图更具吸引力。这是基本的无线电组。我想要的是只选择一张卡片而不是默认的检查按钮。

<form id="myForm">
<input type="radio" name="radioName" value="1" /> 1 <br />
<input type="radio" name="radioName" value="2" /> 2 <br />
<input type="radio" name="radioName" value="3" /> 3 <br />
</form>

你可以试试这个

.container {
    display: block;
    position: relative;
    padding-left: 35px;
    margin-bottom: 12px;
    cursor: pointer;
    font-size: 22px;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

.container input {
    position: absolute;
    opacity: 0;
    cursor: pointer;
}

.checkmark {
    position: absolute;
    top: 0;
    left: 0;
    height: 25px;
    width: 25px;
    background-color: #eee;
    
}

.container:hover input ~ .checkmark {
    background-color: #ccc;
}

.container input:checked ~ .checkmark {
    background-color: #2196F3;
}


.checkmark:after {
    content: "";
    position: absolute;
    display: none;
}

.container input:checked ~ .checkmark:after {
    display: block;
}

.container .checkmark:after {
 	top: 9px;
	left: 9px;
	width: 8px;
	height: 8px;
