【问题描述】:
我正在尝试创建一个由三个 div 组成的简单网页:包含图像的标题 div、包含文本的内容 div 和包含导航元素和徽标的导航 div。我的目标是将标题 div 与导航 div 重叠,以便导航元素和徽标始终垂直居中放置在标题 div 的下边框上。
到目前为止,这是我的代码:
<!DOCTYPE html>
<html>
<head>
<title>TITLE</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
body {
text-align: center;
}
#headerimage {
height: 100%;
width: 100%;
z-index: 50;
position: relative;
}
#headerimage > img {
max-width: 100%;
max-height: 100%;
border: 6px;
border-style: solid;
border-color: #671013;
}
#nav {
width: 100%;
overflow: visible;
top: 97.75%;
z-index: 100;
position: absolute;
}
#nav > img {
text-align: center;
vertical-align: middle;
margin-top: -6.2%;
height: 20%;
width: 20%;
}
.nav-element {
width: 10%;
height: 100%;
padding: 5px;
font-family: Impact, Haettenschweiler, 'Arial Narrow Bold', sans-serif;
text-align: center;
font-weight: bold;
border: 4px;
border-style: solid;
border-color: #2d3139;
background-color: white;
color: #80857f;
}
.nav-element:hover {
background-color: #2d3139;
color: white;
cursor: pointer;
}
.left {
float: left;
z-index: 100;
}
.first {
margin-left: 3%;
}
.right {
float: right;
z-index: 100;
}
.last {
margin-right: 3%;
}
#point2 {
margin-left: 9%;
}
#point3 {
margin-right: 9%;
}
#content {
height: 100%;
width: 100%;
}
#text {
padding-top: 8%;
padding-left: 3%;
padding-right: 3%;
padding-bottom: 5%;
text-align: justify center;
font-family: Impact, Haettenschweiler, 'Arial Narrow Bold', sans-serif;
}
</style>

<div id="point3" class="nav-element right last">
Point 3
</div>
<div id="point4" class="nav-element right">
Point 4
</div>
</div>
</div>
<div id="content">
<div id="text">

目前导航 div 并没有保持在下边界的中心,我的在线研究到目前为止还没有带来任何有用的结果,所以如果有人有想法指出我正确的方向,我会非常感激!

什么时候不居中?当你调整屏幕大小时?

是的,我尝试使用带百分比的边距,但到目前为止没有成功
