Wie erstelle ich eine minimierte Seitenleiste?

Ich kann den Hauptinhalt nicht nach links verschieben. Der folgende Code sorgt dafür, dass der Textinhalt nach rechts verschoben wird, wenn ich auf die Schaltfläche „Öffnen“ klicke: 

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;
  }
}

Wie Sie sehen können, wenn ich versuche, .style.marginRight = "250px" zu ändern, wird der Rand vergrößert, der Inhalt wird jedoch nicht nach links verschoben. Ich möchte den Inhalt nach links verschieben können.

    我不确定我是否完全理解你的问题。 但我认为你是故意这样做的

    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;
}

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

    考虑使用transform:translateX()来代替。它的性能也更高，因为浏览器不必像使用 margin 那样在每个动画帧（每秒 60 帧，以 1/16 秒为单位）执行布局计算。

    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;
}
