If you add a clear:both to your navigation div it will come down and you should remove the height of your .header to fit the content. so it will just fit the provided image. here is the code:

$(document).ready(function() {
  $("#slider").animate({
    "left": $(".item:first").position().left + "px",
    "width": $(".item:first").width() + "px"
  }, 0);

  $(".item").hover(function() {
    $("#slider").stop();
    $("#slider").animate({
      "left": $(this).position().left + "px",
      "width": $(this).width() + "px"
    }, 500);
  });

  $(".item").on("mouseout", function() {
    $("#slider").stop();
    $("#slider").animate({
      "left": $('#one').position().left + "px",
      "width": $('#one').width() + "px"
    }, 500);
  });
});

body{ /* Applies to the <body> tag */
	margin:0px; /* Sets the margin on all sides to 0px */
}
.container{ /* The container class */
	width:100%; /* This sets the width */
	height:100%; /* This sets the height */
	background-color:black; /* Sets the background colour */
}

}
