I really want to make a full page layout on Neopets, but I've tried and can't do it. I already know how to make a regular layout, just want to learn how to do a full page layout. Anyone willing to help me or teach me? Thanks!

When you say "Full Page Layout" what do you mean? Do you have an example of a "Regular" layout and a "Full" layout?

This is a full page layout

This is a regular layout

I think this is what you're looking for:
<style type="text/css">
i.d{background:url(http://yourimagehere.jpg) no-repeat;
height:1100; width:800; position:absolute; top:20; left:100;}
</style><i class="d"> </i>

<style type="text/css">
body{background:26BDEC}
</style>
<style type="text/css">
img{filter: alpha(Opacity=0, FinishOpacity=1, Style=2, StartX=0, FinishX=80, StartY=0, FinishY=80)}
p img {FILTER:
progid:DXImageTransform.Microsoft.Alpha( Opacity=100, FinishOpacity=100, Style=1, StartX=0, FinishX=100, StartY=0, FinishY=100)
(color=white)}
table{background:transparent}
</style>

Change the parts in bold and you should have what you want.

I hope this helps. Have a nice day! :)
