</div>
<span style="font-size:30px;cursor:pointer" onclick="openNav()">☰ open</span>

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: 15px;
color: #818181;
display: block;
transition: 0.3s;
}
.sidenav a:hover {
color: #f1f1f1;
}
.sidenav .closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}

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

在侧边栏中，根据其当前的大小和链接数量，滚动条是否显示。我想为侧边栏中的链接设置150像素宽的列，并使滑块仅在没有更多位置放置新列时显示。如何做到这一点？

2020年3月10日版：我希望链接像在文本栏中一样排列：

• 关于
• 服务
• 客户端
• 联系人

等。

Answer 1

您可以尝试将其添加到您的CSS:中

.sidenav a {
min-width: 50px;
float: left;
}
@media (max-width: 480px) {
.sidenav a {
float:none;
}}

通过使用媒体查询，您可以仅为较小的屏幕(如480px以下的所有屏幕(设置侧边栏链接的样式。
