选择单选按钮时保留其边框效果

Question

我有两个无线电类型选项。当我选择一个选项时，会标记蓝色边框。问题是，如果我点击其他地方，边框效果就会消失。

我希望无论我点击哪里，蓝色边框效果都会保留，除非我切换到其他选项。

另外，我怎样才能将“跨度”中的价格放在右侧，并将产品名称保留在左侧？

Answer 1

您已将蓝色边框的代码放入单选按钮的 :focus 中，您只需将该代码添加到单选按钮的 :checked 中即可。

.radio-custom:checked + .radio-custom-label{
      outline: 1px solid blue;
    }

.checkbox-custom, .radio-custom {
        opacity: 0;
        position: absolute;   
        }
        .checkbox-custom, .checkbox-custom-label, .radio-custom, .radio-custom-label {
        display: inline-block;
        vertical-align: middle;
        margin: 5px;
        cursor: pointer;
        }
        .checkbox-custom-label, .radio-custom-label {
        position: relative;
          display: flex;
          align-items: center;
          padding-right: 10px;
        }
.checkbox-custom-label span, .radio-custom-label span{
  margin-left: auto;
}
        .checkbox-custom + .checkbox-custom-label:before, .radio-custom + .radio-custom-label:before {
        content: '';
        background: #fff;
        border: 2px solid #000;
        display: inline-block;
        vertical-align: middle;
        width: 20px;
        height: 20px;
        padding: 2px;
        margin-right: 10px;
        text-align: center;
        }
        .checkbox-custom:checked + .checkbox-custom-label:before {
        background: rebeccapurple;
        box-shadow: inset 0px 0px 0px 4px #fff;
        }
        .radio-custom + .radio-custom-label:before {
        border-radius: 50%;
        margin: 10px;
        }
        .radio-custom:checked + .radio-custom-label:before {
        background: #000;
        box-shadow: inset 0px 0px 0px 4px #fff;
        }
        .checkbox-custom:focus + .checkbox-custom-label, .radio-custom:focus + .radio-custom-label {
        /*         outline: 1px solid blue; */
/*         width:50%; */
        }
        .radio-custom-label{
        background: #f4f4f4;
/*         width: 50%; */
        }
        .radio-custom:checked + .radio-custom-label{
          outline: 1px solid blue;
        }
    </style>

 <div>
    <input id="pA" value="{{ pago_normal  }}" class="radio-custom" name="radio-group" type="radio">
    <label for="pA" class="radio-custom-label">ProductA
    <span>0</span>
    </label>
</div>
<div>
    <input id="pB" value="{{ pago_cuotas }}" class="radio-custom" name="radio-group" type="radio">
