usually = significantly more then 50% of the time ;)

better = when the web application is faster and easier to maintain  :-)

with CSS coming slow from server its even worser then dynamic pages
when they get slow - you see the page and then while you look or even
start to scroll, elements jump around/get recolored while CSS arrives.

I'd try to avoid this.

What do you expect to change with Z3? Otoh, not using runtime-generated
CSS is usually a better approach anyway.


Just out of interest, why do you think this is *usually* better? This 
does strongly depend on your use case, no?


You could say something like "it is usually better to serve static HTML 
pages" as well.

Hi,
What is the best way of handling CSS?
I've looked at ZStylesheets, but it is buggy and uses depreciated 
functions that will not be available in 2.10.



I recommend a DTML Document as an upgrade to File objects.
If you use DTML you can
a) easily set some custom cache headers in the css


Or use a cache manager :-)


b) refer to images by a dynamic URL to the imagefolder. *

* example:
#body { background:#fff url(/bg.png); }


Which runs against (a) because if you aggressive cache
(which is a good idea) you shouldn't have dynamic elements
in it.

I believe file objects are good enough and you could
probably split the CSS across some files to get the
dynamics w/o loosing performance.


I also use DTML for dynamic stylesheets plus a HTTPCacheManager and a 
set_header script to set the text/css media type (and /* vim: set 
syn=css: */).


Only because I'm lazy to change the paths (mainly for @import) in the 
stylesheets.
