How to overlap the Nav bar instead of pushing content to right?-CodePudding

I'm using the same code in my website. Is there any way open the nav bar and overlap on right, without pushing content to right? https://codepen.io/dalisc/pen/qzRGxQ

I experimented with position and z-index, but didn't help. Thank you

<div id="mySidebar" class="sidebar" onmouseover="toggleSidebar()" onmouseout="toggleSidebar()">
    <div class="navContent">
  <a href="#">YOUR DASHBOARD</a><br>
  <a href="#">MESSAGE CENTER</a><br>
  <a href="#">IMPACT & OUTCOMES</a><br>
  <a href="#">LEARNERS</a><br>
  <a href="#">PROGRAMS</a>
  <a href="#">SETTINGS</a>
  </div>
</div>

.sidebar {
        height: 100%;
        width: 85px;
        position: fixed;
        z-index: 1;
        top: 0;
        left: 0;
        background-color: #181633;
        transition: 0.5s;
        padding-top: 120px;
        white-space: nowrap;
        overflow-x: hidden;
}
.sidebar a {
        padding: 3px 8px 3px 32px;
        text-decoration: none;
        font-size: 16px;
        color: #D3D2E4;
        display: block;
}

CodePudding user response：

set document.getElementById("mySidebar").style.width = "85px"; instead of document.getElementById("mySidebar").style.width = "250px";

var mini = true;

function toggleSidebar() {
  if (mini) {
    //console.log("opening sidebar");
    document.getElementById("mySidebar").style.width = "250px";
    /*change this line*/
    document.getElementById("main").style.marginLeft = "85px";
    /*change this line*/
    this.mini = false;
  } else {
    //console.log("closing sidebar");
    document.getElementById("mySidebar").style.width = "85px";
    document.getElementById("main").style.marginLeft = "85px";
    this.mini = true;
