CSS i Netscape.

Hej, jeg er ved at lave webside og forsøger at bruge CSS ark til siderne.

Her er koden:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<HTML>
<HEAD>

<!-- Minus AutoDato -->
    <TITLE>Jonas Kristensen</TITLE>

<META NAME="Generator" CONTENT="Stone's WebWriter 3.5">

<!-- <STYLE TYPE="text/css" HREF="css/submenu.css" REL="stylesheet" TYPE="text/css" -->

<STYLE TYPE="text/css">

DL {
    font-size:large;
    font-family:sans-serif;
    font:bold;
}

DT {
    color:#993399;
    font-size:medium;
    font-family:sans-serif;
    font:bold;
    text-decoration:underline;
}
</STYLE>

</HEAD>
<BODY>

<DL>
    <DT>Tidstunnel-fotosamling
        <DD>My comma within parentheses in an argument list is treated as part of the argument, not as an argument delimiter. Note there can be no whitespace between the macro identifier and the (. The optional arg_list is a sequence of identifiers separated by commas, not unlike the argument list of a C function. Each comma-delimited identifier plays the role of a formal argument or placeholder.
        </DD>
    <DT>Familie og venner
        <DD></DD>   
    <DT>Tegninger
        <DD>Use the virtual keyword to allow derived classes to provide different versions of a base class function. Once you declare a function as virtual, you can redefine it in any derived class, even if the number and type of arguments are the same. The redefined function overrides the base class function.
        </DD>
</DL>


<TABLE WIDTH="570" HEIGHT="100%" BORDER="1" ALIGN="left" CELLSPACING="5" CELLPADDING="0">
    <TR VALIGN="top">
        <TD WIDTH="400"><!-- Celle til forklaring af menuer -->
            sdfsfsfsdfsfs
        </TD>
        <TD><!-- Celle til flydemenu -->
        <DIV ALIGN="left"></DIV>   
        </TD>   
    </TR>
</TABLE>



</BODY>
</HTML>


I internet explorer kan jeg se formateringen, men i netscape har CSS arket ingen virkning.

Jeg har hørt at netscape godt kan tolke CSS, så hvad gør jeg ?
