I thought something looked "off" but it may just be my memory lying to me - I'm pretty sure the default (or maybe just the trend) in the mid-90s was for gray backgrounds rather than white. I see from the source that this page is a straight copy with no background set so in modern browsers it defaults to white.

Or perhaps it's just me? I would've been 10 at the time but we did have internet access at home (Dad needed it for work) so perhaps I'm mis-remembering.
