Q: 

How do I remove the top margin in a web page?

I have had this problem with every web page I have created. There is always a top margin above the 'main container' div I use to place my content in the center of the page. I am using a css style sheet and have set margins and padding in the body to 0px and set the margin and padding to 0 in the div: 

body{
    margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px;
    padding: 0;
    color: black; font-size: 10pt; font-family: "Trebuchet MS", sans-serif;
    background-color: #E2E2E2;}


div.mainContainer{
    height: auto; width: 68em;
    background-color: #FFFFFF;
    margin: 0 auto; padding: 0;}

I have looked online many times, but all I can see to do is set these margin and padding attributes. Is there something else I should be doing? The margin exists in IE and Firefox.

Here is a more thorough look at the code (it is in the beginning stages of creation, so there isn't much in it...)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
<html xmlns="http://www.w3.org/1999/xhtml"&gt;

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <!-- TemplateBeginEditable name="doctitle" -->
        <title></title>
    <!-- TemplateEndEditable -->
    <!-- TemplateBeginEditable name="head" --><!-- TemplateEndEditable -->
    <link href="../Styles/KB_styles1.css" rel="stylesheet" type="text/css" />
</head>

<body>
<div class="mainContainer">
    <p>Here is the information</p>
</div>
</body>
</html>

Here is the CSS:

@charset "utf-8";
/* CSS Document */

body{
    margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px;
    padding: 0;
    color: black; font-size: 10pt; font-family: "Trebuchet MS", sans-serif;
    background-color: #E2E2E2;}

/* ---Section Dividers --------------------------------------------------------------*/
div.mainContainer{
    position: relative; height: auto; width: 68em;
    background-color: #FFFFFF;
    margin: 0 auto; padding: 0;}

div.header{padding: 0; margin: 0;}

div.leftSidebar{
    float: left;
    width: 22%; height: 40em;
    margin: 0;}

div.mainContent{margin-left: 25%;}

div.footer{
    clear: both;
    padding-bottom: 0em; margin: 0;}

/* Hide from IE5-mac. Only IE-win sees this. \*/
   * html div.leftSidebar { margin-right: 5px; }
   * html div.mainContent {height: 1%; margin-left: 0;}
/* End hide from IE5/mac */

Line height? margin/padding on elements in the mainContainer? Can you show the HTML or do you have a site where we can see it in action?

Do you have Firefox/Firebug and/or Web Developer plugins? Looking at the computed CSS in Firebug or outlining elements with Web Developer can help figure out where the space is coming from.

Is your first element h1 or similar? That element's margin-top could be causing what seems like a margin on body.

Here is the code that everyone was asking for -- its at the very beginning of development so there isn't much in it yet, which may be helpful...

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

<html xmlns="http://www.w3.org/1999/xhtml"&gt;
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <!-- TemplateBeginEditable name="doctitle" -->
        <title></title>
    <!-- TemplateEndEditable -->
    <!-- TemplateBeginEditable name="head" --><!-- TemplateEndEditable -->
    <link href="../Styles/KB_styles1.css" rel="stylesheet" type="text/css" />
</head>

<body>
<div class="mainContainer">
  <div class="header">  </div>
  <div class="mainContent">  </div>
 <div class="footer">  </div> 
</div>
</body>
</html>

Here is the css:

@charset "utf-8";
/* CSS Document */

body{
    margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px;
    padding: 0;
    color: black; font-size: 10pt; font-family: "Trebuchet MS", sans-serif;
    background-color: #E2E2E2;}

html{padding: 0; margin: 0;}

/* ---Section Dividers -----------------------------------------------*/
div.mainContainer{
    height: auto; width: 68em;
    background-color: #FFFFFF;
    margin: 0 auto; padding: 0;}

div.header{padding: 0; margin-bottom: 1em;}

div.leftSidebar{
    float: left;
    width: 22%; height: 40em;
    margin: 0;}

div.mainContent{margin-left: 25%;}

div.footer{
    clear: both;
    padding-bottom: 0em; margin: 0;}

/* Hide from IE5-mac. Only IE-win sees this. \*/
* html div.leftSidebar { margin-right: 5px; }
* html div.mainContent {height: 1%; margin-left: 0;}
/* End hide from IE5/mac */

Cannot reproduce problem in any browser.

Thanks for the tip about where to put this. I didn't know what to do. I will add it now.
