html - 动态添加DIVS

我正在尝试动态添加子div，它会自动调整其父div的大小，但是我的CSS无法正确呈现它们。下面的代码

的HTML

<head>
        <title>Dealer Services Hub</title>
    </head>
    <body>
        <div id="wrapper">
            <div id="header">
             </div>
            </div>

            <div id="body">

                <div id = "maindiv">
                    <div class = 'maindivs'>Sales/Credit</div>
                    <div class = 'maindivs'>Finance</div>
                    <div class = 'maindivs'>Compliance/Audit</div>
                    <div class = 'maindivs'>Admin</div>
                    <div class = 'maindivs'>Reporting</div>
                    <div class = 'maindivs'>EOT</div>
                    <div class = 'maindivs'>Test</div>

                </div>

                <div id = "sidebardiv">

                     <div class = 'sidebardivs' div id = 'recentsdiv'><div id = 'recentlinkstitle'>Frequent Views</div></div>
                  <div class = 'sidebardivs' div id ='dealercommentsdiv'>Dealer Comments</div>
                  <div class = 'sidebardivs'>Dealers</div>

                </div>

            </div>

    <!--Footer Div-->
         <div id="footer">
             <div>
                 <span>USBNet</span>
             </div>

             <div>
                <span>Best In Us</span>
             </div>

             <div>
                <span>Directory</span>
             </div>


         </div>

        </div>



</body>


的CSS

}

#body{
    width: 100%;
    height: 100%;
    float: left;
    color:#0C2074;
}

h2{
  font-family: Arial, "Helvetica Neue", Helvetica, sans-serif;
}

#wrapper {
    width:1400px;
    margin: 0;
    padding: 0;
    height: 100%;
    overflow:auto;
}

#header{

    box-shadow: 10px 10px 8px #888888;
    text-align: center;
    float: left;
    margin-top: 20px;
    margin-left: 20px;
    cursor:pointer;
    border-radius: 10px;
    color:#0C2074;
}


#sidebardiv{
    width:300px;
    height:100%;
    float: left;
    border-left: 1px solid #5a5a5a;
    overflow:hidden;
}


.sidebardivs{
    width:90%;
    height: 220px;
    border: 1px solid #000000;
    background: #e5e5e5;
    color:#0C2074;

#recentsdiv{
    font-size: 95%;
}

    text-align: center;
    float: left;
    margin-bottom: 20px;
    cursor:pointer;
}

#footer{
    width: 1320px;
    height:40px;
    float: left;
    background: #0C2074;
    clear: both;
    color:#FFF;
}

#footer div{
    width:33.33%;
    height: 100%;
    text-align: center;
    float: left;
    margin: auto;
    padding-top: 5px;
    padding-right: 5px;;
    padding-bottom: 5px;
    padding-left: 5px;
    border-left: 1px solid #67B2E8;
    border-right: 1px solid #67B2E8;
    font-size: 120%;
    box-sizing: border-box;
}


额外的div是父级“ maindiv”的“ Test”，父级“ sidediv”的“ Dealers”，结果是“ Test” div似乎已被切断，并且“ Dealers” div之间的间隔更大超过必要

最佳答案

现在好点了吗：
