Making BXslider full screen (filling entire browser window)

I am currently trying to implement THIS very simple content slider. I have reached a point where it is working, however using the CSS code below I need to make the slider full screen, filling the entire browser window. However I can not see where to put the code for this can someody help me? I feel like a bit of a dummy for asking such a simple question!

My current code is below.

My HTML code

<body>

<div class="slider">
<ul class="bxslider">
<li><img src="images/slide1.png" /></li>
<li><img src="images/slide2.png" /></li>
<li><img src="images/slide3.png" /></li>
</ul></div>

</body>

My CSS code

.bx-wrapper {
position: relative;
left: 0px;
top: 0px;
padding: 0;
*zoom: 1;
}

.bx-wrapper img {
max-width: 100%;
height: 100%;
display: block;
}

Solution

Here you are a full screen bxSlider + responsive. http://jsfiddle.net/0nj2ry4n/1/

First remove the images and make them background of the li elements.

<ul class="bxslider">
  <li style="background-image: url('http://bxslider.com/images/home_slides/hillside.jpg');"></li>
  <li style="background-image: url('http://bxslider.com/images/home_slides/houses.jpg');"></li>
  <li style="background-image: url('http://bxslider.com/images/home_slides/hillside.jpg');"></li>
  <li style="background-image: url('http://bxslider.com/images/home_slides/houses.jpg');"></li>
</ul>

Then add this css

*{
    margin: 0px;
    padding: 0px;
}
body, html{
    height: 100%;
}
.bx-viewport, .bx-wrapper{
    position:relative;
    width:100%;
    height:100% !important;
    top:0;
    left:0;
}
.bxslider, .bxslider li{
    height: 100% !important;;
}
.bxslider li{
    background-repeat: no-repeat;
    background-position: top center;
    background-size: cover;
}
.bx-wrapper .bx-viewport{
    border: none !important;
}

And call bxSlider

$(document).ready(function(){
    $('.bxslider').bxSlider({
        pager: false
    });
});
