[solved] Problem with Slidecast Plugin

[Former Member]

I solved the problem (:
Changed this:
html {
border-top: 5px solid #fff;
background: #58DDAF;
color: #2a2a2a;
}

To:
html {
border-top: 5px solid #fff;
background: transparant;
color: #2a2a2a;
}

I've been working on my forum for the last few days and solved a lot of problems myself, but this is a thing I can't seem to fix (or find a solution for), so I hoped you could help me out. The trouble is that my background seems to stop at the 'end' of my forum, instead of being full-screen. In the printscreens you can see the teal-bar beneath my forum - which shouldn't be there. The source seems to be my Slidecast plugin I use for my header.

Printscreens:



The original code for the plugin is from: codepen.io/zuraizm/pen/vGDHl
I believe I made some minor changes, but I am not sure any more. I hope you guys can help me out.

I've put this in the forum wrapper
<div id="slider">
<a href="#" class="control_next"><img src="http://s1.postimg.cc/ik1pupwm3/star_silver.png"></a>
<a href="#" class="control_prev"><img src="http://s1.postimg.cc/ik1pupwm3/star_silver.png"></a>
<ul>
<li><img src="http://s11.postimg.cc/aogtbtoo3/header_736px_1.png"></li>
<li style="background: #aaa;"><img src="http://s11.postimg.cc/dwlaovaxv/header_736px_2.png"></li>
<li><img src="http://s11.postimg.cc/k02v8s17n/header_736px_3.png"></li>
<li style="background: #aaa;"><img src="http://s11.postimg.cc/52ue7rnz7/header_736px_4.png"></li>
</ul>
</div>

And those two in the plugin:
Javascript
jQuery(document).ready(function ($) {

$('#checkbox').change(function(){
setInterval(function () {
moveRight();
}, 3000);
});

var slideCount = $('#slider ul li').length;
var slideWidth = $('#slider ul li').width();
var slideHeight = $('#slider ul li').height();
var sliderUlWidth = slideCount * slideWidth;

$('#slider').css({ width: slideWidth, height: slideHeight });

$('#slider ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });

$('#slider ul li:last-child').prependTo('#slider ul');

function moveLeft() {
$('#slider ul').animate({
left: + slideWidth
}, 200, function () {
$('#slider ul li:last-child').prependTo('#slider ul');
$('#slider ul').css('left', '');
});
};

function moveRight() {
$('#slider ul').animate({
left: - slideWidth
}, 200, function () {
$('#slider ul li:first-child').appendTo('#slider ul');
$('#slider ul').css('left', '');
});
};

$('a.control_prev').click(function () {
moveLeft();
});

$('a.control_next').click(function () {
moveRight();
});

});
