不爱废话，直接贴代码

CSS ：（主要弹出框css）

/*弹出层*/.modal{
       position: fixed;    top: 0;    right: 0;    bottom: 0;    left: 0;    z-index: 1050;    display: none;    overflow: hidden;    -webkit-overflow-scrolling: touch;    outline: 0;    background-color: rgba(0, 0, 0, 0.5);}.modal .modal-dialog{
       position: relative;    width:auto;    margin: 10px;}.modal .modal-content{
