如何滚动固定的双导航栏？
[英]How to scroll a fixed double navbar?
问题描述
所以我有两个固定的响应式导航栏。 这是我的代码：
function myFunction() { var x = document.getElementById("myTopnav"); if (x.className === "topnav") { x.className += " responsive"; } else { x.className = "topnav"; } }
body { margin: 0; font-family: Arial, Helvetica, sans-serif; } .outer { position: fixed; top: 0px; widtH: 100%; } .topnav { overflow: hidden; background-color: #333; } .topnav a { float: left; display: block; color: #f2f2f2; text-align: center; padding: 14px 16px; text-decoration: none; font-size: 17px; } .topnav a:hover { background-color: #ddd; color: black; } .active { background-color: #4CAF50; color: white; } .topnav .icon { display: none; } @media screen and (max-width: 600px) { .topnav a:not(:first-child) {display: none;} .topnav a.icon { float: right; display: block; } } @media screen and (max-width: 600px) { .topnav.responsive {position: relative;} .topnav.responsive .icon { position: absolute; right: 0; top: 0; } .topnav.responsive a { float: none; display: block; text-align: left; } } .secondnav { background:red; width:100%; height:42px; }

问题是，当调整窗口大小并且导航栏变得响应并且我单击菜单按钮时，由于导航栏中有很多项目，因此我无法滚动浏览菜单。 如何解决这个问题？ 请不要建议其他方法。 请尝试使用此代码。
并预先感谢！

您可以添加以下CSS：
@media screen and (max-width: 600px) {
.topnav.responsive {
position: relative;
max-height: 75vh; /* Set to the hegith you want to use */
overflow-y: scroll; /* Enable scroll */
}
如果您不想显示滚动条，只需添加：
.topnav.responsive::-webkit-scrollbar {
width: 0px; /* remove scrollbar space */
background: transparent; /* optional: just make scrollbar invisible */
}
function myFunction() { var x = document.getElementById("myTopnav"); if (x.className === "topnav") { x.className += " responsive"; } else { x.className = "topnav"; } }
body { margin: 0; font-family: Arial, Helvetica, sans-serif; } .outer { position: fixed; top: 0px; widtH: 100%; } .topnav { overflow: hidden; background-color: #333; } .topnav a { float: left; display: block; color: #f2f2f2; text-align: center; padding: 14px 16px; text-decoration: none; font-size: 17px; } .topnav a:hover { background-color: #ddd; color: black; } .active { background-color: #4CAF50; color: white; } .topnav .icon { display: none; } @media screen and (max-width: 600px) { .topnav a:not(:first-child) {display: none;} .topnav a.icon { float: right; display: block; } } @media screen and (max-width: 600px) { .topnav.responsive { position: relative; max-height: 75vh; /* Set to the hegith you want to use */ overflow-y: scroll; /* Enable scroll */ } .topnav.responsive .icon { position: absolute; right: 0; top: 0; } .topnav.responsive a { float: none; display: block; text-align: left; } } .secondnav { background:red; width:100%; height:42px; }
