Ive been making a website with a CSS3 menu. However during the validating process to check if i made no mistakes i broke my CSS3 menu. The menu itself works but theres no drop down menu when hovering "Categorieen" like it did before.
Heres the HTML:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-type" content="text/html;charset=utf-8" />
<title>Website Ronald</title>
<script src="js/jquery.js" type="text/javascript"></script>
<script src="js/jquery.js" type="text/javascript"></script>
<link rel="stylesheet" href="style.css"/>
<style type="text/css">
html {
background: url(images/image2.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
}
</style>
</head>
<body style="margin:0px;padding:0px;overflow:hidden">
<ul id="menu">
<li><a href="Home.html" target="frame_a">Home</a></li>
<li><a href="Categorieen.html" target="frame_a">Categorieën</a></li>
<ul>
<li><a href="Sub/Vliegvelden.html" target="frame_a">Vliegvelden</a></li>
<li><a href="Sub/Landschappen.html" target="frame_a">Landschappen</a></li>
<li><a href="Sub/Auto`s.html" target="frame_a">Auto`s</a></li>
</ul>
<li><a href="Over.html" target="frame_a">Over</a></li>
</ul>
<div align="center">
<iframe src="home.html" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden; height:90%;width:75%;position:absolute;top:60px;left:160px;right:0px;bottom:10px" width="75%" height="90%" name="frame_a" marginheight="5" frameborder="0"></iframe>
</div>
</body>
</html>
