CSS – The difference between CSS positioning in Windows and Linux

The difference between CSS positioning in Windows and Linux… here is a solution to the problem.

The difference between CSS positioning in Windows and Linux

I’m having trouble rendering my html page using the same browser in different operating systems.
There are 3 spans, and the position of each span is corrected by CSS (position:relative).
But I found that the page that looks correct in Firefox under Linux is not displayed correctly in the same Firefox (3.5.7) under Windows OS.

Linux (left – how it should be)/Windows (right): link text

The same goes for other browsers. What is the cause of this problem and how to fix it.
My code:
Question .html:

<! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <link href="css/question.css" rel="stylesheet" media="all" />
        <div class="eventFullDate">
            <span class="eventYear">2010</span>
            <span class="eventDate">17</span>
            <span class="eventMonth">FEB</span>

Question .css:

html, body{
    font-family: Georgia;
    height: 39px;
    width: 31px;
    float: left;
    border: 1px solid;
    border-color: #E3E3E3;
    background-color: #F7FFFF;

span.eventYear, span.eventDate, span.eventMonth{
    color: #EC5C1D;
    position: relative;
    width: 100%;

    left: 1px;
    bottom: 3px;
    font-size: 0.8em;

    left: 5px;
    bottom: 12px;
    font-size: 1.3em;

    left: 3px;
    bottom: 15px;
    font-size: 0.8em;


You should use CSS-reset, which will help standardize your CSS for better cross-browser compatibility: http://developer.yahoo.com/yui/reset/

Also, you have this

html, body{
 font-family: Georgia;

I’m guessing one of your operating systems doesn’t have Georgia fonts. Probably the Windows version.
