我正在尝试调整 "How To - Side Navigation"从 w3schools.com 出现在屏幕右侧,但遇到困难。下面提供了来自 w3schools 的示例,以及我的尝试。

I've found with my attempt, the 'x' for the exit button is persistent on the webpage (but is still functional) & the height of the navbar is only the height of the unordered list.

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>

}

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

如何将 Sidenav Push Example 更改为来自屏幕右侧?

最佳答案

像这样,将 .sidenav 中的 left: 0; 更改为 right: 0; 并在脚本中更改 style.marginLeftstyle.marginRight(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>
