css widescreen remedies

[tolgraven]

Some issues:

Not good on wide screen widths. Don't even have to go very wide to manifest.

Stop using wv for height on main page - bleeding galore when wide.
Appears --space-sides not seeing use where needed - could use it in combo with --space-edges to fix eg. blog content becoming too wide.

Probably a lot more but those are the main ones to fix if I'm gonna try shoving my page in people's faces and expect them to see what I see.
