HTML & CSS
1

Ok, so I have looked at a 100 examples online today for css drop down. changing them all the my classes/id’s and it never works. I have applied the simplest parts of the drop down css to my code. Can anyone tell me what i need to add? It won’t even display when i hover

HTML:

<html>
<head>
<link href="style.css" rel="stylesheet" type="text/css"/>

</head>
    <body>
		<div id="content">
	<div id="logo">
		<img src=".png" width="600" height="82" ><a href=""></a>
	</div>
			<div id="surround">[B]
            <div id="nav">
                <ul>
                    <li><a href="">button</a></li>
                         <ul>
                              <li><a href="">sub-button</a></li>
                              <li><a href="">sub-button</a></li>
                         </ul>
                    <li><a href="">button</a></li>
                    <li><a href="">button</a></li>
                    <li><a href="">button</a></li>
                </ul>
            </div>[/B]
        	</div>
        </div><!-- end of content" div -->
        <div id="footer-wrap">
            <div id="footer">
                <p>content</p>
                <p>content</p>
                <p>content</p>
            </div> <!-- end of "footer" div --> 
        </div><!-- end of "footer-wrap" div -->

    </body>
</html>

CSS:

body {
	background: #fff;

#content {
	width: 970px;
	margin: auto;
	padding: 0px 10px 10px 10px;

	border-left: 2px solid #000;
}

#logo {
	margin: 0px 0px 0px 10px;
}


#nav {
	float: right;
	display: block;
	margin: -16px 0 0 0;
}

#nav li {
	list-style-type: none;
	display: inline;
	float: right;
	font-size: 16px;
	position: relative;
	top: -84px;
	right: 7px;
}

#nav a {
	text-decoration: none;
	color: #000;
	font-family: Trebuchet MS, sans-serif;
	font-weight: bold;

	border-left: 2px solid #000;
	margin: 5px;

}

#nav a:link, a:visited {
	color: #000;
	-webkit-transition: color .25s linear .05s;
	transition: color .25s linear .05s;
}

#nav a:hover {

}

/*my basic drop down code that needs help */
[B] #nav ul ul {
 	display: none;
 }

 #nav ul ul:hover {
 	display: block;
 }
[/B]

#footer-wrap {

	margin: auto;
	padding: 10px;

}

#footer p {

In viewing all of those examples, you missed one of the key points, that the sub ul goes inside its parent li:

[COLOR="#FF0000"]<li>[/COLOR]<a href="">button</a>
	<ul>
	<li><a href="">sub-button</a></li>
	<li><a href="">sub-button</a></li>
	</ul>
[COLOR="#FF0000"]</li>[/COLOR]

But there are lots of problems with the CSS, too, so I’ve tidied it up for you in the example below. I removed the surrounding div, as that’s not needed, and also it’s best to avoid all those negative top and left positions and negative margins etc. That’s a sign of poor layout strategy anyway.

If you like, we can help you with the larger layout as well.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
	
<style media="all">
body, ul, li {margin:0; padding: 0;}

#nav {
	float: right;
	display: block;
	margin: 0 0 0 0;
	list-style: none;
}

#nav > li {
	float: left;
	font-size: 16px;
	position: relative;
	margin-left: 5px;
}

#nav a {
	text-decoration: none;
	color: #000;
	font-family: Trebuchet MS, sans-serif;
	font-weight: bold;
	padding: 8px 13px 8px 13px;
	border-color: #000;
	border-style: solid;
	border-width: 0 2px 2px;
	display: block;
}

#nav a:link, a:visited {
	color: #000;
	-webkit-transition: color .25s linear .05s;
	transition: color .25s linear .05s;
}

#nav a:hover {
	color: #fff;
	background: #000;
}

#nav ul {
	position: absolute;
	left: -9999px;
	list-style: none;
}

#nav li:hover ul {
	left: 0;
}
</style>
	
</head>
<body>

<ul id="nav">
<li><a href="">button</a>
	<ul>
	<li><a href="">sub-button</a></li>
	<li><a href="">sub-button</a></li>
	</ul>
</li>
<li><a href="">button</a></li>
<li><a href="">button</a></li>
<li><a href="">button</a></li>
</ul>


</body>

i think “<ul>” should not be used in the sub menu just check it in w3schools website

No, it’s perfectly fine to do that—utterly valid HTML. :slight_smile:

just check it in w3schools website

There are much better places to check.

Erm, Don’t cite w3schools. They are wildly inaccurate most of the time. The site is a link farm, nothing more, using a deceptive name to try to look like a legitimate representative of the w3c. It is not.
