Remove the 1px border underneath all headers and make them
use black text to simplify visual appearance

The original libvirt logo was built using what appears to be
either Overpass font, or one stylistically very similar (the
slanted top of letters like 'l', 't', etc). The newly recreated
libvirt logo will use Overpass. Use this font for the website
text too, to provide a consistent style.

Add bolding for <dt><code> elements to make them "stick out" on the
page rather that just a stream of text where the elements only differ
by slightly different font style.

The 'body' CSS class is not used anywhere in the HTML files,
so we can get rid of the definition as well.

According to MDN[1], 'margin-left' and similar CSS properties,
including 'margin-right', cannot be applied to the '::first-line'
pseudo-element, so this rule will never have any effect and can
be safely removed.

Headers are bold already, so the font doesn't need to be that
big to draw attention.

Ensure all CSS rules are separated with a single blank line.

- remove top padding for h1. this means page titles sit flush with the top
  of the side bar (like 'The virtualization API' on the front page)
- up the top padding for the remaining sections. makes it visually easier
  to tell adjacent header sections apart, especially in dense wiki pages
- use two different spacing levels for h2-h4 and h5-h6,
  gives pages some more visual flexibility
- use a slightly lower bottom padding... this makes top padding stick out
  more which makes it visually easier to differentiate between adjacent
  header sections

- Add line-height:150% spacing for all text. This makes text lines far
  less cramped, and seems closer visually to what wikipedia uses.

- Remove bottom and top margin from lists: entries seemed needlessly
  spread out.

- Reduce sublist indentation a bit

- Add a bottom border after headings: IMO this greatly helps in break
  up the vertical flow of a big page of text. Doesn't look great on the
  front page, but helps a lot on dense pages like formatdomain

- change font-family to just 'sans-serif' rather than hardcode a few
  font families. this means we abide the user's browser font setting,
  and makes us consistent with other sites like en.wikipedia.org
- raise font-size to 90%. this is what en.wikipedia.org uses.

With these two tweaks, libvirt.org text renders the same as
en.wikipedia.org with fedora firefox out of the box config. Previously
the font on libvirt.org was very small and difficult to read.

- Drop some redundant bits
- Use consistent spacing
- Group similar blocks near each other

There should be no functional change

This is long since obsolete, just scrap it all
