I use code like this at the beginning of a DTML Method that implements
my CSS file:


    <dtml-call "RESPONSE.setHeader('Content-Type', 'text/css')">
    <dtml-call "RESPONSE.setHeader('Last-Modified', bobobase_modification_time().toZone('GMT').rfc822())">
    <dtml-call "RESPONSE.setHeader('Cache-Control','private, max-age=3600')">

    <dtml-if "_.string.find(HTTP_USER_AGENT, 'MSIE') != -1">
    <dtml-comment> Use smaller fonts for MSIE </dtml-comment>
    OL,UL,P,BODY,TD,TR,TH,FORM,.default { font-size: x-small; }
    .smaller, .footer { font-size: xx-small; }
    <dtml-else>
    OL,UL,P,BODY,TD,TR,TH,FORM,.default { font-size: small; }
    .smaller, .footer { font-size: x-small; }
    </dtml-if>


The fixed part of the CSS file follows that.  The first three lines
are my quick&dirty hack to make the URL cacheable (done before Cache
Manager became available).

My code only calls out MSIE as a special case.  You'd have to figure
out the HTTP_USER_AGENT values that apply to the cases you want to
discriminate.
