Bagaimana untuk membuat bar sisi yang runtuh?

Saya tidak dapat mengalihkan kandungan utama ke kiri. Kod di bawah membuatkan kandungan badan bergerak ke kanan apabila saya mengklik butang buka: 

function openNav() {
  document.getElementById("mySidebar").style.width = "250px";
  document.getElementById("main").style.marginLeft = "250px";
}

function closeNav() {
  document.getElementById("mySidebar").style.width = "0";
  document.getElementById("main").style.marginLeft = "0";
}
body {
  font-family: "Lato", sans-serif;
}

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

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

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

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

.openbtn {
  font-size: 20px;
  cursor: pointer;
  background-color: #111;
  color: white;
  padding: 10px 15px;
  border: none;
  margin-left: 1600px;
}

.openbtn:hover {
  background-color: #444;
}

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


/* On smaller screens, where height is less than 450px, change the style of the sidenav (less padding and a smaller font size) */

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

Seperti yang anda lihat, jika saya cuba menukar .style.marginKanan = "250px"; ia meningkatkan margin tetapi tidak mengalihkan kandungan ke kiri. Saya mahu dapat mengalihkan kandungan ke kiri.

    Saya tidak pasti saya memahami sepenuhnya soalan anda. Tapi saya rasa awak sengaja buat 

    function openNav() {
  document.getElementById("mySidebar").style.width = "250px";
  document.getElementById("main").style.marginLeft = "250px";
}

function closeNav() {
  document.getElementById("mySidebar").style.width = "0";
  document.getElementById("main").style.marginLeft = "0";
}
    body {
  font-family: "Lato", sans-serif;
}

.sidebar {
  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;
}

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

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

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

.openbtn {
  font-size: 20px;
  cursor: pointer;
  background-color: #111;
  color: white;
  padding: 10px 15px;
  border: none;
}

.openbtn:hover {
  background-color: #444;
}

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


/* On smaller screens, where height is less than 450px, change the style of the sidenav (less padding and a smaller font size) */

@media screen and (max-height: 450px) {
  .sidebar {

  .sidebar a {

    Pertimbangkan untuk menggunakan transform:translateX()来代替。它的性能也更高，因为浏览器不必像使用 margin untuk melakukan pengiraan reka letak pada setiap bingkai animasi (60 bingkai sesaat, diukur dalam 1/16 saat). 

    function openNav() {
  document.getElementById("mySidebar").style.width = "250px";
  document.getElementById("main").style.transform = "translateX(-250px)";
}

function closeNav() {
  document.getElementById("mySidebar").style.width = "0";
  document.getElementById("main").style.transform = "";
}
    body {
  font-family: "Lato", sans-serif;
}

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

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

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

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

.openbtn {
  font-size: 20px;
  cursor: pointer;
  background-color: #111;
  color: white;
  padding: 10px 15px;
  border: none;
  margin-left: 1600px;
}

.openbtn:hover {
  background-color: #444;
}

#main {
  transition: transform .5s;
  padding: 16px;
}


/* On smaller screens, where height is less than 450px, change the style of the sidenav (less padding and a smaller font size) */

@media screen and (max-height: 450px) {
  .sidebar {
