了解如何使用 CSS 在图片上添加导航菜单。
创建导航栏:
<div class="bg-img">
<div class="container">
<div class="topnav">
<a href="#home">Home</a>
<a href="#news">News</a>
<a href="#contact">Contact</a>
<a href="#about">About</a>
</div>
</div>
</div>
导航栏样式:
.bg-img {
/* The image used */
background-image: url("img_nature.jpg");
min-height: 380px;
/* Center and scale the image nicely */
background-position: center;
background-repeat: no-repeat;
background-size: cover;
/* Needed to position the navbar */
position: relative;
}
/* Position the navbar container inside the image */
.container {
position: absolute;
margin: 20px;
width: auto;
}
/* The navbar */
.topnav {
overflow: hidden;
background-color: #333;
}
/* Navbar links */
.topnav a {
float: left;
color: #f2f2f2;
text-align: center;
padding: 14px 16px;
text-decoration: none;
font-size: 17px;
}
.topnav a:hover {
background-color: #ddd;
color: black;
}
