Css menu design

Webpage menus play necessary part on the web. When designing menus, usability is the key. In this section we are going to show you how to create a simple, usable and functional horizontal menu with HTML and CSS step by step. We assume that you have a basic knowledge of HTML and CSS.

A navigation bar needs standard HTML as a base. In our examples we will build the navigation bar from a standard HTML list. A navigation bar is basically a list of links, so using the <ul> and <li> elements make perfect sense.


Create Navigation menu .

 Example 

<!DOCTYPE html>

<html>

<body>

<ul>

<li><a href="#home"> Home </li>

<li><a href="#About">About us</li> 

<li><a href="#courses">Courses</li>

 <li><a href ="#contacts">Contacts</li>

<li><a href="#downloads">Downloads</li>

</ul>

</body>

</html>

Everything is apparent. While many of the pages on your website are hidden from view in drop-down menus in a horizontal menu, vertical menus let you list every page down the side of the page. Because of this, vertical menus are a fantastic alternative for lengthy, single-page websites and make navigating them easier.

lilist-style-type: none;
