How to get body below header using relative positioning? - php

Question

I am trying to create a page where the header is centered 70% of the window and a body 85% of the window. The header goes on top of the body, but I can't seem to accomplish this. When I add relative positioning to my #body div; the div seems to be positioned relative to the window (body) of the page instead of the header. How do I make it so the #body div is positioned relatively below the #header div so the body is going in the flow of the page? (I want all the elements inside #header to stay exactly where I positioned them).
HTML/PHP
<?php
$resultSet = $db->query("SELECT * FROM table");
if ($resultSet->num_rows != 0)
{
while ($rows = $resultSet->fetch_assoc())
{
$id = $rows["id"];
$images = $rows["image"];
$title = $rows["title"];
if ($id <= 3)
{
//Front page Div that contains all the header elements
echo "<div id=header>";
if ($id == 1)
{
//The front page div that contains the large image and the title
echo "<div id=largeDiv>";
echo "<img src=$images>";
//Div inside of largeImg div, that creates semi-transparent block for title
echo "<div id=largeTitle>";
//Main title of header
echo "<h2>$title</h2>";
echo "</div>"; //End of largeTitle div
echo "</div>"; //End of largeDiv
}
//Secondary div inside of #header that goes on the right side of #largeDiv
echo "<div id=smallDiv>";
if ($id == 2)
{
//Left image
echo "<img id=leftImg src=$images>";
}
if ($id == 3)
{
$text = $rows["text"];
//Right image
echo "<img id=rightImg src=$images>";
//Secondary div's title
echo "<h2>$title</h2>";
//Secondary div's text
echo "<p>$text</p>";
}
echo "</div>"; //End of smallDiv
echo "</div>"; //End of header
}
else
{
echo "<div id=body>";
if ($id <= 13)
{
echo "<div id=left>";
echo "<img src=$images>";
echo "</div>";
}
echo "</div>";
}
}
}
?>

Answer 1

body is a page construct and can't be repositioned, so the position style has no acutal effect.
What would be better is if your header content #header was inside another element such as a HTML5 style header, and perhaps #body inside a main container.
So, for example;
<body>
<header>
<div id="header">
Header Content Here
</div>
</header>
<main>
<div id="body">
<div id="left">
Left Content
</div>
</div>
</main>
</body>
CSS
header {
width: 100%;
}
#header{
position: relative;
width: 70%;
height: auto;
margin: 1.5% auto;
}
main {
width: 100%;
}
#body {
position: relative;
width: 85%;
margin: 0 auto;
}
#left {
width: 28.33%;
}
The above is an incomplete solution, but it's an example of how you look to structure your page.
An altnernative is to have a container (like #container) around all the content with the max width of the inner content.
