Adding transition to Side nav bar

Issue

I have a site with a side navigation bar that is supposed to slide in via the right side, then when you close it, it transitions back into the side. When designing this i realized that after clicking the side bar once it overrides my style of “transition:0.5s” and instead just appears.

Here is my code

window.onclick = function(event){if(event.target == document.getElementById('outerNav')){closeNav();}};

function openNav() {
document.getElementById("outerNav").style.display = "block";
    document.getElementById("outerNav").style.transition = "0.5s";
document.getElementById("jrc-sidenav").style.width = "250px";
document.getElementById("et-main-area").style.opacity = "0.7";
document.getElementById("jrc-sidenav-background").style.backgroundColor = "rgba(255,255,255,0.7)";
document.getElementById("hamburger").style.display = "none";

}

function closeNav() {
document.getElementById("jrc-sidenav").style.width = "0";
document.getElementById("et-main-area").style.opacity = "1";
document.getElementById("jrc-sidenav-background").style.backgroundColor = "#fff";
document.getElementById("hamburger").style.display = "block";
    setTimeout(function(){
        document.getElementById("outerNav").style.display = "none";
},500);
}
.outerNav {
  display: none;
  position: fixed;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  overflow: hidden;
  background-color: transparent;
  transition: 0.5s;
}

Solution

The Problem is your outer-nav. When you open the menu it got set to “display:block” – that happens without a transition.
If you also resize it from 0% to 100% with a transition, it should work. See the snippet:

window.onclick = function(event) {
  if (event.target == document.getElementById('outerNav')) {
    closeNav();
  }
};

function openNav() {

  document.getElementById("outerNav").style.position = "fixed";
  document.getElementById("outerNav").style.width = "100%"; //added this for opening the menu
  document.getElementById("mySidenav").style.width = "250px";
  document.getElementById("main").style.marginLeft = "250px";
  document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}

function closeNav() {
  document.getElementById("mySidenav").style.width = "0";
  document.getElementById("main").style.marginLeft = "0";
  document.getElementById("outerNav").style.width = "0%";
  document.body.style.backgroundColor = "white";

}
body {
  font-family: "Lato", sans-serif;
  transition: background-color .5s;
}

.sidenav {
  height: 100%;
  width: 0;
  position: fixed;
  z-index: 1;
  top: 0;
  left: 0;
  background-color: #111;
  overflow-x: hidden;
  transition: 0.5s;
  padding-top: 60px;
}

.sidenav a {
  padding: 8px 8px 8px 32px;
  text-decoration: none;
  font-size: 25px;
  color: #818181;
  display: block;
  transition: 0.3s;
}

.sidenav a:hover {
  color: #f1f1f1;
}

.sidenav .closebtn {
  position: absolute;
  top: 0;
  right: 25px;
  font-size: 36px;
  margin-left: 50px;
}

#main {
  transition: margin-left .5s;
  padding: 16px;
}

@media screen and (max-height: 450px) {
  .sidenav {
    padding-top: 15px;
  }
  .sidenav a {
    font-size: 18px;
  }
}

.outerNav {
  display: block;
  position: fixed;
  left: 0;
  top: 0;
  width: 0%;
  /* 0% when Menu is closed */
  height: 100%;
  overflow: hidden;
  background-color: transparent;
  transition: .5s;
}
<body>
  <div id="outerNav" class="outerNav">
    <div id="mySidenav" class="sidenav">
      <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
      <a href="#">About</a>
      <a href="#">Services</a>
      <a href="#">Clients</a>
      <a href="#">Contact</a>
    </div>
  </div>
  <div id="main">
    <h2>Sidenav Push Example</h2>
    <p>Click on the element below to open the side navigation menu, and push this content to the right. Notice that we add a black see-through background-color to body when the sidenav is opened.</p>
    <span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; open</span>
  </div>
</body>
