将屏幕左侧的屏幕外导航栏转换为屏幕右侧时出现的问题

Question

我正在尝试改编w3schools.com的“操作方法-侧面导航” ，使其出现在屏幕的右侧，但遇到了困难。 下面提供了w3schools的示例以及我的尝试。

我已经尝试过，退出按钮的“ x”在网页上是永久存在的（但仍然可以使用），导航栏的高度仅是无序列表的高度。

Sidenav推送示例（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="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>

我该怎么做才能将Sidenav推送示例更改为屏幕右侧？

这样，您在left: 0; 在.sidenav中right: 0; 然后在脚本style.marginLeft style.marginRight更改为style.marginRight （请注意，这发生在2个地方）

 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"; }

 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; } }

 <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>
