css 部分

.pages{
    text-align: center;
    padding: 20px 0;

    .prev,.next {
        width: auto;
        background: transparent;
        -moz-box-sizing: border-box;
        -webkit-box-sizing: border-box;
        box-sizing: border-box;
    }

    a{
        display: inline-block;
        width: 18px;
        height: 18px;
        line-height: 18px;
        border-radius: 3px;
        text-align: center;

        font-size: 14px;
        vertical-align: top;

    }

    .disabled{
