Okay, you said that you wanted a left navigational menu so i am going to use lissa's template for that...
<html>
<head>
<title>Two Column CSS Layout</title>
<style type="text/css">
body
{ margin-top: 0;
margin-bottom: 0;
margin-left: 0;
margin-right: 0;
padding-left: 0;
padding-right: 0;
}
#menu {
position: absolute;
left: 5px;
padding: 0px;
width: 150px;
}
#content {
margin-left: 200px;
padding: 0px;
margin-right: 15px;
}
</style>
</head>
<body>
<div id="menu">
Your menu will go here. You can place images, text links, etc. in this div. To change the properties of this layer you can change the #menu selector in the style sheet that is located on this page between the head tags.
</div>
<div id="content">
All of your content goes in this div. This side is fluid so that if the window is collapsed, your div will collapse also and fit the screen perfectly. To change the properties of this div you can change the #content selector in the style sheet that is located on this page between the head tags.
</div>
</body>
</html>
to have an external syle sheet, make a CSS file and call it style.css and then take all the bold above and cut and paste into your CSS file and get rid of the <style> tags...
then, in the head tags of each page that you want to use this style sheet... put
<LINK href="style.css" rel="stylesheet" type="text/css">
Then... you should have something that looks like this...
<html>
<head>
<title>Two Column CSS Layout</title>
<LINK href="style.css" rel="stylesheet" type="text/css">
</head>
<body>
<div id="menu">
Your menu will go here. You can place images, text links, etc. in this div. To change the properties of this layer you can change the #menu selector in the style sheet that is located on this page between the head tags.
</div>
<div id="content">
All of your content goes in this div. This side is fluid so that if the window is collapsed, your div will collapse also and fit the screen perfectly. To change the properties of this div you can change the #content selector in the style sheet that is located on this page between the head tags.
</div>
</body>
</html>
Now whatever you want to put in your menu, would would put in that sections and anything you want in your content, you would put in that section... make more sense now?
