I think that we should also consider consistently using em or %, not both.
There are some subtle differences, see http://kyleschaeffer.com/user-

The differences are not that subtle. :-)
For "font-size", there are no differences, subtle or other, 1em and 100% are
exactly the same, 83% and 0.83em are exactly the same, and are related to
the parental "font-size". You can replace one with the other but there is no
need to do so, it changes nothing.
For "width" there is a huge, not subtle difference, percents are related to
the parental "width", ems are related to the parental "font-size". You
cannot replace one with the other.

PmWiki.css specifies font-size in a number of ways, e.g.
font-size:11pt;
font-size:0.9em;
font-size:100%;
font-size:1em;
font-size:85%;
font-size:9.4pt;
font-size:1.6em;
It seems to me we should revisit this with a view to using one way
throughout, and supporting responsive design.
Note that always 1em = 100%, 0.9em = 90% etc. that is related to the font
size of the parent HTML node.
The "points" are indeed absolute units with a fixed size (1pt = 1/72 of an
inch) but modern browsers don't enforce them for text sizes if a visitor
resizes the text with Ctrl+Scroll or Ctrl+Plus.
Anyways, as browsers all seem to imply that 12pt=100% for a base page, I
changed the 3 occurences I found to percents:
body: 11pt = 11/12 = 91.667%
sidebar: 9.4pt = 9.4/11 = 85.45%
%sidehead%: 11pt = 11/9.4 = 117%
With the browsers I have the page looks exactly the same as before, pixel
for pixel.
If there is a better way to do it (without disturbing existing wikis
much), please share it.
