Hello Adrian
Try something like this:
html, body {
background: #2d335e url(../img/Aurora.png) top center repeat-
x;
}
<body>
<div class="unit on-3 columns">
<div class="fixed column" style="width: 200pt;">
<div id="logo" class="container"><img src="img/logo2.png"
alt="Logo" id="logo" /></div>
</div>
<div class="elastic column">
<div id="content" class="container box"> </div>
</div>
<div class="fixed column" style="width: 200pt;">
<div id="right_nav" class="container box"> </div>
</div>
</div>
</body>
That happened because thats the default behavior of body tag, you
should not apply that classes to the body tag, use a div instead also
you need to add html to the css body rule too.
Hope that help.
Cheers.
