废话不多说 贴代码

.limits {
    padding: 20px 50px 0px;
}
.limits section{
    padding: 0px 50px;
}

.limits input[type=checkbox] {
    visibility: hidden;
}

    .limits .checkbox {
        width: 15px;
        height: 15px;
        background-color: #5A8BFF !important;
        position: relative !important;
        border: 1px solid #5A8BFF !important;
        display: inline-block;
        margin: 0 !important;
        top: 2px;
    }


    .limits .checkbox label {

注释掉这一段

.limits input[type=checkbox] + label:after {
    content: '\00a0' !important;
    display: inline-block !important;
    border: 2px solid #5A8BFF !important;
    border-top-width: 0 !important;
    border-right-width: 0 !important;
    width: 9px !important;
    height: 5px !important;
    -webkit-transform: rotate(-50deg) !important;
    position: absolute !important;
    top: 3px !important;
    left: 3px !important;
    z-index: 1 !important;
}
