Question

我正在尝试将w3schools.com中的"How To - Side Navigation"调整为从屏幕右侧显示，但我遇到了困难。下面提供了w3schools的例子，以及我的尝试。

我发现尝试时，退出按钮的'x'是持久的在网页上（但仍然有效）＆amp;导航栏的高度是只有无序列表的高度。

Sidenav Push示例（左）：

<!DOCTYPE html>
<html>
<style>
body {
    font-family: "Lato", sans-serif;
}

.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, .offcanvas a:focus{
    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;}
}
</style>
<body>

<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 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.</p>
  <span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; open</span>
</div>

<script>
function openNav() {
    document.getElementById("mySidenav").style.width = "250px";
    document.getElementById("main").style.marginLeft = "250px";
}

function closeNav() {
    document.getElementById("mySidenav").style.width = "0";
    document.getElementById("main").style.marginLeft= "0";
}
</script>

</body>
</html>

我的尝试：

<!DOCTYPE html>
<html>
<style>
body {
    font-family: "Lato", sans-serif;
}

.sidenav {
    height: 100%;
    width: 0;
    position: inherit;
    z-index: 1;
    top: 0;
    left: 0;
    float: right;
    background-color: #4D394B;
    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: 0.0s
}

.sidenav a:hover, .offcanvas a:focus{
    color: #f1f1f1;
}

.sidenav .closebtn {
    float: left;
    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;}
}
</style>
<body>

<div id="mySidenav" class="sidenav">

  <a href="#">About</a>
  <a href="#">Services</a>
  <a href="#">Clients</a>
  <a href="#">Contact</a>
</div>

<div id="main">

如何更改Sidenav Push示例来自屏幕右侧？

Answer 1

像这样，您将left: 0;中的.sidenav更改为right: 0;，然后在脚本中将style.marginLeft更改为style.marginRight（请注意，这会发生在2个地方）

＆＃13;

function openNav() {
  document.getElementById("mySidenav").style.width = "250px";
  document.getElementById("main").style.marginRight = "250px";
}

function closeNav() {
  document.getElementById("mySidenav").style.width = "0";
  document.getElementById("main").style.marginRight = "0";
}

＆＃13;

body {
  font-family: "Lato", sans-serif;
}
.sidenav {
  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;
}
.sidenav a {
  padding: 8px 8px 8px 32px;
  text-decoration: none;
  font-size: 25px;
  color: #818181;
  display: block;
  transition: 0.3s
}
.sidenav a:hover,
.offcanvas a:focus {
  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;
  }
}

＆＃13;

<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 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 left.</p>
  <span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; open</span>
</div>
