Not directly related to vibe.d, but I noticed that in Opera 12
the layout of your Phobos test with your documentation
generator doesn't look right. For example here:
The content isn't rendered side-by-side with the menu on the
left, but under it. If you find the time, maybe you can see if
anything can be done about it, Sönke. Opera has usually been
good with CSS compliance. That said, it looks right on the
minimal zoom level.
