我如何让我的侧边菜单推动我的网站？

Question

我为网站创建了侧边导航，但我不希望它覆盖在我的网站之上。我希望它推翻网站的其余部分。例如他们如何在this website 上做到这一点。我的代码如下。

<div id="mainbox" onclick="openFunction()">&#9776; </div>
        <div id="menu" class="sidemenu">
            <a href="#">Home</a>
            <a href="#">Shop</a>
            <a href="#">About</a>
            <a href="#">Contact</a>
        <a href="#" class="closebtn" onclick="closeFunction()">&times;</a>
 </div>

<script type="text/javascript">
        function openFunction(){
            document.getElementById("menu").style.width="400px";
            document.getElementById("mainbox").style.marginLeft="400px";
 }
        function closeFunction(){
             document.getElementById("menu").style.width="0px";
             document.getElementById("mainbox").style.marginLeft="0px";
}
</script>

CSS：

#mainbox{
 position: fixed;
 font-size: 40px;
 cursor: pointer;
 transition: all .6s;
 transform: translate(3750%, -1600%);
}

.sidemenu{
 position: fixed;
 top: 0px;
 right: 0px;
 height: 100%;
 width: 0px;
 background-color: #FFEECA;
 z-index: 1;
 padding-top: 100px;
 overflow-x: hidden;
 transition: all .5s;
}

.sidemenu a{
 padding: 8px 8px 8px 64px;
 text-decoration: none;
 font-size: 20px;
 color: #222;
 display: block;
}

.sidemenu a:hover{
  color: white;
}

.sidemenu .closebtn{
 position: absolute;
 top: 0px;
 right: 25px;
 font-size: 36px;
 margin-left: 32px;
}
