【问题描述】:
在以下 w3schools 代码中,该代码在网页底部实现了响应式菜单,我添加了一个 div,其中包含域的版权声明。我想让版权 div 在屏幕底部居中只要它没有被菜单项覆盖,随着浏览器窗口变小,然后再次移动到页面底部在菜单项被菜单项覆盖时或在菜单项之前已最小化时通过相关按钮打开时位于菜单项下方。
function myFunction() {
var x = document.getElementById("myNavbar");
if (x.className === "navbar") {
x.className += " responsive";
} else {
x.className = "navbar";
}
}
body {
margin: 0;
font-family: Arial, Helvetica, sans-serif;
}
.navbar {
overflow: hidden;
background-color: #333;
position: fixed;
bottom: 0;
width: 100%;
}
.navbar a {
float: right;
display: block;
color: #f2f2f2;
text-align: center;
padding: 14px 16px;
text-decoration: none;
font-size: 17px;
}
.navbar a:hover {
background-color: #ddd;
color: black;
}
.navbar a.active {
background-color: #04AA6D;
color: white;
}
.navbar .icon {
display: none;
}
#copyright {
position: absolute;
top: 20%;
left: 25%;
width: 50%;
height: 50%;
color: white;
}
@media screen and (max-width: 600px) {
.navbar a:not(:first-child) {
display: none;
}
.navbar a.icon {
float: right;
display: block;
}
}
@media screen and (max-width: 600px) {
.navbar.responsive .icon {
position: absolute;
right: 0;
bottom: 0;
}
.navbar.responsive a {
float: none;
display: block;
text-align: left;
}
}
<!DOCTYPE html>
