Oh lol, you said vertical gradient whereas it should have been horizontal ;o
And well, if you look at the side you'll see it's wrapped in two div boxes so making it fluid would kind ruin that >_>
How'd you find it? ;O
And thanks! :D Sadly, This one can't be fixed to fluid width because the header is the official TCG art
:( I had to exhaust every bit of it's normal width for what you see right now xD
