CSS代码:

 

 div,p,ul,li{
    margin: 0;
    padding: 0;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}
    ul li{
        list-style-type: none;
    }
 .page-sidebar-menu .left-a {
        display: block;
        font-size:12px;
        color:#03478b;
        text-decoration: none;
        -webkit-transition: all 0.4s ease;
        -o-transition: all 0.4s ease;
        transition: all 0.4s ease;
    }
    .page-sidebar-menu li.active {
        background: #bbbbbb;
    }
    .tab-link{
        padding:5px;
        margin:2px 0;
        background-color:#E4EFFB;
    }
    p.active {
        background: #5A86A8;
    }
    .page-sidebar-menu p.active a {
        color:#fff;
    }
    .submenu {
        display: none;
        background: #444359;
        font-size: 14px;
    }

    .submenu li {
        border-bottom: 1px solid #4b4a5e;
    }

    .submenu a {
        display: block;
        text-decoration: none;
        color: #d9d9d9;

        padding: 5px;
        -webkit-transition: all 0.25s ease;
        -o-transition: all 0.25s ease;
        transition: all 0.25s ease;
