Today I am going to share with you a tutorial to create multilevel header navigation bar in CSS3 in a very simple manner.
Simple minimalistic Css 3 multilevel navigation
This CSS3 navigation is supported by modern browser only i.e. Chrome, Mozilla, Safari etc. The earlier version of IE 6 or 7 will not be compatible for this navigation.
Step 1
Open Dreamweaver or and other HTML editor and create an html file and name it index.html (or any other name), Put following code into it and save the doc.
<!DOCTYPE html>
<html>
<head>
<title>Simple Minimal CSS3 Navigation by W3update.com</title>
<link rel="stylesheet" type="text/css" href="css3-navigation.css">
<style type="text/css">
body {
background: url('img/pattern.png');
}
.nav {
top: 150px;
left: 150px;
}
</style>
</head>
<body>
<ul class="nav">
<li><a href="#">Home</a></li>
<li class="dropdown">
<a href="#">My Work</a>
<ul>
<li><a href="#">Design</a></li>
<li><a href="#">Webdesign</a></li>
<li><a href="#">Webdevelopment</a></li>
<li class="dropdown">
<a href="#">Identity</a>
<ul>
<li><a href="#">Level 2</a></li>
<li class="dropdown">
<a href="#">Level 2</a>
<ul>
<li><a href="#">Level 3</a></li>
<li><a href="#">Level 3</a></li>
<li><a href="#">Level 3</a></li>
<li><a href="#">Level 3</a></li>
<li><a href="#">Level 3</a></li>
<li><a href="#">Level 3</a></li>
</ul>
</li>
<li><a href="#">Level 2</a></li>
<li><a href="#">Level 2</a></li>
</ul>
</li>
<li><a href="#">App Development</a></li>
</ul>
</li>
<li><a href="#">Services</a></li>
<li><a href="#">Blog</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Contact</a></li>
</ul>
</body>
</html>Step 2
Create a CSS file called navigation.css (or choose any other name) if you are choosing any other name the same should be rightly mentioned in html file at code line 6 where external link is linked. Put following CSS codes into it and save it.
