<label> <input class="radio_type" type="radio"/>免费</label>
 <label> <input class="radio_type" type="radio" />积分</label>
 <label> <input class="radio_type" type="radio" />现金</label>

.radio_type {
    width: 20px;
    height: 20px;
    appearance: none;
    position: relative;
    outline: none;
}
.radio_type:before {
    content: "";
    width: 15px;
    height: 15px;
    border: 1px solid #19874f;
    display: inline-block;
    border-radius: 50%;
    vertical-align: middle;
}
.radio_type:checked:before {
    content: "";
    width: 15px;
    height: 15px;
    border: 1px solid #19874f;
    display: inline-block;
    border-radius: 50%;
    vertical-align: middle;

    content: "";
    width: 9px;
    height: 9px;
    text-align: center;
    background: #19874f;
    border-radius: 50%;
