html - 单选按钮选中的属性不起作用

Question

我正在尝试在 radio 的标签上悬停效果，因为它工作正常，但我想要实现的是:

如果我选择一个单选按钮，相应的标签应该有一些背景色

我尝试了很多组合，但它对我不起作用。任何帮助将不胜感激。

您必须更改标签父级并放入相同的 <td>所以CSS适用于它，

.checkout_beautify {
    font-size: 16px;
    line-height: 45px;
    font-weight: bold;
    border: 1px dotted black;
    -webkit-transform: scale(1.1);
    -moz-transform: scale(1.1);
    -o-transform: scale(1.1);
    -ms-transform: scale(1.1);
    transform: scale(1.1);
    transition: all 400ms;
    border-radius: 25px;
    text-align: center;
}
.checkout_beautify:hover {
    font-size: 16px;
    line-height: 45px;
    font-weight: bold;
    border: 1px dotted black;
    border-radius: 25px 4px 25px 4px;
    background: #1B1B1B;
    color: #ffffff;
    transition: all 4ms;
    text-align: center;
}
label[for=bank_transfer]:hover {
    font-size: 16px;
    line-height: 45px;
    font-weight: bold;
    border: 1px dotted black;
    border-radius: 25px 4px 25px 4px;
    background: #1B1B1B;
    color: #ffffff;
    transition: all 4ms;
    text-align: center;
}
label[for=icicipg]:hover {
    font-size: 16px;
    line-height: 45px;
    font-weight: bold;
    border: 1px dotted black;
    border-radius: 25px 4px 25px 4px;
    background: #1B1B1B;
    color: #ffffff;
    transition: all 4ms;
    text-align: center;
}
/*CHANGE FOLLOWING*/
.radio input[type="radio"]:checked + label {
    background: pink;
}
.radio input[type="radio"]:checked + label * {
    background: pink;
}

label { float:left; clear:none; }
input[type=radio] { float:left; clear:none; margin: 2px 0 0 20px; }

<table class="radio">
    <tbody>
        <tr class="highlight">
            <td>
                <input type="radio" name="payment_method" value="payu" id="payu" checked="checked">
            
                <label for="payu">
                    <h3 class="checkout_beautify"><b>PAYU MONEY -  (Credit/Debit/NetBanking)</b></h3>
                </label>
            </td>
            <td></td>
        </tr>
        <tr class="highlight">
            <td>
                <input type="radio" name="payment_method" value="icicipg" id="icicipg">
            
                <label for="icicipg">ICICI PAYMENT GATEWAY - (Credit/Debit)</label>
            </td>
            <td></td>
        </tr>
        <tr class="highlight">
            <td>
                <input type="radio" name="payment_method" value="citrus" id="citrus">
            
                <label for="citrus">
                    <h3 class="checkout_beautify"><b>CITRUS - (Netbanking)</b></h3>
                </label>
            </td>
            <td></td>
        </tr>
        <tr class="highlight">
            <td>
                <input type="radio" name="payment_method" value="bank_transfer" id="bank_transfer">
            
                <label for="bank_transfer">
                    <h3><b>DEPOSIT IN BANK</b></h3>
                </label>
            </td>
            <td></td>
        </tr>
    </tbody>

您必须使用 css 才能进行适当的布局。

如果你想在你的代码中使用 Jquery 那么它很好，你可以很容易地实现它。喜欢，
