Ok, download the example files and lets start coding !

Step 1. HTML

As usual, we start with the HTML. Here are full html code of our menu. As you can see – this is multilevel menu built on UL-LI elements. But, it is a little unusual. I don’t wrap submenus into own UL element, I am going to hide them, and display if necessary.

index.html

01 <!DOCTYPE html>
02 <html lang="en" >
03     <head>
04         <meta charset="utf-8" />
05         <title>CSS3 multilevel menu with transition and animation | Script Tutorials</title>

12             <a href="https://www.script-tutorials.com/css3-multilevel-menu-with-transition-and-animation/" class="stuts">Back to original tutorial on <span>Script Tutorials</span></a>
13         </header>
14         <div class="container">
15             <ul id="nav">
16                 <li>
17                     <a href="#">Parent link #1</a>
18                     <a href="#">Sub #11</a>
19                     <a href="#">Sub #12</a>
20                     <a href="#">Sub #13</a>
21                     <a href="#">Sub #14</a>
22                 </li>
23                 <li>
24                     <a href="#">Parent link #2</a>
25                     <a href="#">Sub #21</a>
26                     <a href="#">Sub #22</a>
27                     <a href="#">Sub #23</a>
28                     <a href="#">Sub #24</a>
29                 </li>
30                 <li>
31                     <a href="#">Parent link #3</a>
32                     <a href="#">Sub #31</a>
33                     <a href="#">Sub #32</a>
34                     <a href="#">Sub #33</a>
35                     <a href="#">Sub #34</a>
36                 </li>
37                 <li>
38                     <a href="#">Parent link #4</a>
39                     <a href="#">Sub #41</a>
40                     <a href="#">Sub #42</a>
41                     <a href="#">Sub #43</a>
42                     <a href="#">Sub #44</a>
43                 </li>
44             </ul>
45         </div>
46     </body>
47 </html>

Step 2. CSS

Here are the CSS styles of our menu. Maybe you’ve noticed – that in our html – I have two CSS files: layout.css and menu.css. The first file (layout.css) contain the styles of our test page. We will not publish these styles in this article, but if you wish – you can find these styles in our package.
