I'm viewing the site on my mobile right now and it doesn't have any of the custom styling. It's all gray with generic fonts. I was on my desktop an hour ago and it looked fine. Is there a stylesheet that's gone missing or is this by design?
Here is a screenshot.
Update I'm back at a desktop and it looks fine. I think it's really a mobile issue because when I used Safari on the Mac and changed the user agent to iPhone there again was no style.
Resolution Hendrik points me in the right direction below. It's not a bug; it's a feature. Mods, if you could tag this status-bydesign that would be best.
