Here’s the deal. I have a main navigation css. I’d like to create an 
alternate template and instead of replacing the nav.css with a new 
flavored nav.css, I’d like to put my color rules in a theme css file.


Since I've only glanced at the solutions referred to in some of the 
other post, I might be wrong, but it seems that they all break the 
caching aspect of CSS as well as requiring the re-parsing of the style 
sheet each time. There is no need for this to happen.


For starters, have mod_rewrite redirect all CSS requests to the template 
engine and have the desired style sheet as a query string. The style 
sheet template and values to be inserted can be stored either as files, 
in a database, or a combination. The engine pulls the time stamp from 
the template and the values, compares them to the time stamp in the HTTP 
headers, sets the outgoing headers to reflect if it's sending a style 
sheet or not, and finally, parses the template only if needed.


This technique can be extended (and possibly abused) to take advantage 
of other header, cookie, or session info.


Another option is store frequently accessed style sheets on the server 
pre-parsed.

 Well, no -- I frequently use variables in style sheets built in JSP,
 especially early on in development. And there it's simple Expression
 Language (EL) variable substitution, so something like this:
 
 a:hover, a:focus { color: ${contrastColor}; }
 
 can be evaluated per site, per session, or even per request, making
 it really easy to test, tune, and/or customize...
 
 FWIW!

You can also do almost the same thing with PHP just do the following:

?php

$variable=do your declarations here;
$bg=#fff
$h1=100;
$w1=20em;
header('Content-Type: text/css');
echo 

html{
color:#123;
background:$bg;
}

#header{
height:{$h1}px;
width:$w1;
}
;
?

note that it's important that there are double quotes on the echo and
not single.

CSS doesn't do variables, but here's something recently mentioned on the 
css-d list that does something close to what I believe you are 
describing, using php:

RE: [WSG] css variables

2005-09-28 Thread Terrence Wood 
yeah, I thought you meant you were using 56K lines of code to replace 4
lines of CSS... sounded like overkill to me when a one line regex can do
the same thing.

Constants and variables are not going to part of CSS any time soon, so you
will need some kind of server side solution - a few are mentioned in this
thread already.

AFAIK they all use seom form of regex to do the replacement, so
s/selectedLink/#f60/g still works for me =)


kind regards
Terrence Wood.

And as a side note, with MSIE, it is possible to give an ASP extension to
the styles sheet to use scripting logic within that file.

ASP, PHP or whatever server side language you use, as long as you set the appropriate content type on (in) the file (be it css.asp, css.php or whatever) it should work in more browsers than just MSIE.  

I just ran a test and it worked fine in Opera 8, Firefox, MSIE6 and MSIE5 PC.  If it's served as text/css and the output is valid css, it shouldn't matter what the extension is.

If I said MSIE it's because one does *not* need to change the MIME type ;)
