CSS: How to remove white space

<p>I am designing a responsive web page. Actually what's happening is though i am setting the width of my header and wrapper with the screen size still I guess it is taking more space due to which a horizontal scroll bar appears down the screen and also the position of buttons are varying from display to display though i am taking the screen size px Here is the code</p><pre><br /><code>$(document).ready(function(){<br /> var a=window.screen.availWidth;<br /> var b=(0.20 * window.screen.availHeight);<br /> var c=(0.60 * window.screen.availHeight);<br /> $("#header").css("background-color","#009acd");<br /> $("#header").css("height",b);<br /> $("#header").css("width",a);<br /> $("#header").css("position","relative");<br /><br /> $("#wrapper").css("background-color","#FFFFFF");<br /> $("#wrapper").css("width",a);<br /> $("#wrapper").css("height",c);<br /> $("#wrapper").css("position","relative");<br /><br /> $("#logo1").css("position", "absolute");<br /> $('#logo1').css("top","5%");<br /><br /> $('#d11').css("position","absolute");<br /> $('#d11').css("top","75px");<br /> $('#d11').css("left","310px");<br /> $('#d11').css("color","#FFFFFF");<br /><br /> $('#marquee').css("position","absolute");<br /> $('#marquee').css("top","-15px");<br /> $('#marquee').css("left","300px");<br /> $('#marquee').css("color","#FFFFFF");<br /><br /> $('h1').css("color","#FFFFFF");<br /> $('h3').css("position","absolute");<br /> $('h3').css("top","90px");<br /> $('h3').css("left","1000px");<br /> $('h3').css("color","#FFFFFF");<br />

$('#css3menu1').css("bottom","17px");<br /> $('#css3menu1').css("left","310px");<br /><br /> $('#videos').css("position", "absolute");<br /> $('#videos').css("top","0px");<br /> $('#videos').css("left","22px");<br /><br /> $('#studymaterial1').css("position", "absolute");<br /> $('#studymaterial1').css("top","148px");<br /> $('#studymaterial1').css("left","32px");<br /><br /> $('#downloads').css("position", "absolute");<br /> $('#downloads').css("top","315px");<br /> $('#downloads').css("left","22px");<br /><br /> $('#wowslider-container1').css("left","233px");<br />
