title: Difference in css-positioning in windows and linux
body: <p>I have a problem with rendering my html page by the same browsers in different OS. 
  There are 3 spans and position of each span is corrected through css(position:relative).
  But I have found out that the page that looks correct in firefox under Linux, shows not right at the same firefox(3.5.7) under Windows OS. </p>
  
  <p>Linux(Left - How it should be)/Windows(right): <a href="http://img62.imageshack.us/img62/5686/linwin.png" rel="nofollow noreferrer">link text</a></p>
  
  <p>And the same with other browsers. What is the cause of this problem and how is possible to solve it.
  My code:
  question.html:</p>
  
  <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
      &lt;head&gt;
          &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/&gt;
          &lt;title&gt;Question&lt;/title&gt;
          &lt;link href="css/question.css" rel="stylesheet" media="all" /&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;div class="eventFullDate"&gt;
              &lt;span class="eventYear"&gt;2010&lt;/span&gt;
              &lt;span class="eventDate"&gt;17&lt;/span&gt;
              &lt;span class="eventMonth"&gt;FEB&lt;/span&gt;
          &lt;/div&gt;
      &lt;/body&gt;
  &lt;/html&gt;

  <p>question.css:</p>
  
  <pre><code>html, body{
