  Units:  (compare http://www.w3.org/TR/CSS2/syndata.html#length-units)

  px: for absolute pixel dimensions related to images or border widths

  pt: should - in theory - be 1/72th of an inch and less sensitive to different resolutions compared to px
      but: it is not generally so :(   =>  avoided;

  main font size:
     => by recommendation (http://www.w3.org/QA/Tips/font-size) defined as  ..., small, medium, ..
     => reason: should be the most device independent option
     => in practice: depends on the browser settings; opera => tools => prefs => fonts => webpage normal text => choose => change font size
     => defined only once for the body, the rest  is scaled using em, which refers to this

  em: relative to the main font size (assigned to the body) - e.g. headers relative to the main size;
      also border padding, table widths, spacing between fonts etc.
