first post so please go easy with me,

I want to put header, sidebar, and possibly footer over the top of my fullscreen slider. so that the full screen slider is full background can anyone point to me what I doing wrong. before the wife kills me for spending too much time trying to figure this out.

<?php wp_head(); ?>

<style type="text/css">
html, body {
margin:0 !important;
padding:0 !important;


<body bgcolor="#cccccc">
<?php get_header(); ?>
<?php get_sidebar(); ?>
<?php if(have_posts()) : while(have_posts()) : the_post(); the_content(); endwhile; endif; ?>
<?php get_footer(); ?>


any help greatly appreciated
