How to insert the horizontal navigation bar css into Wordpress?

Q: I am creating a new site using Wordpress, I tried the "insert to page" and work fine on html page, but wondering how to insert the CSSMenu into Wordpress menu?

I am working on Windows 7, Firefox/IE, and currently using the free version to test before buying.

A: CSS3Menu wasn't developed as Wordpress or any other CMS extension, BUT you can use it.

See how should you install CSS3Menu on your page:
1. You should create your menu and publish it on a local drive in any test folder.
2. Open .html file from the saved folder in any text editor
(you'll find folder with images and .css file in this saved folder also).
3. Copy code for the HEAD and BODY sections of CSS3Menu.
4. In Wordpress go to "HTML" tab and paste it in the place where you want to have a menu, for example:

<!-- Start HEAD section -->
<link rel="stylesheet" href="menu_files/style.css" type="text/css" />
<!-- End HEAD section -->

<!-- Start BODY section -->
<ul id="css3menu" class="topmenu">
<p style="display:none"><a href="">Buttons Using CSS</a></p>
<!-- End BODY section -->

5. Notice, you should copy generated folder (with "style.css" file and images) into the same folder with your own webpage.
6. Preview your website in the browser.

That's all.
