Nested definiations in CSS

[robin9876]

In a CSS I want to define a custom color and the use this in other
parts of the css such as the body tag defination. How do I need to
define the CSS file to be able to do this?

If you are asking whether you can use a variable name in css
that you can assign to somewhere else in your stylesheet, the
answer is no. This sort of thing is very easy to do with a
preprocessor, and for something simple like this, just about any
preprocessor that is available for your system will do.

I've never tried this, but a think (as Lars says) you can try to
preprocess it on server side.
Just link a *.php file instead of *.css and this *.php can just prepare
and serve you typical css file combining some template with variables,
variables definitions.

Remember about serving proper headers (mime type)

Server-side processing may be overkill, depending on exactly what the OP
needs to do. If it's the equivalent of simple macro expansion, then I'd
run it through a preprocessor (command-line PHP, for example) /before/
uploading.

Unless the style sheet really needs to be dynamic (some content might be
based on user preferences, for example), it's a waste of server time.
Doing it properly may entail calculating the Content-Length header value
yourself, and ensuring that freshness and validator information is
included, too. Using a static file allows the server to take care of all
of that for you.

Preprocessing before upload requires a little more effort that simply
uploading and serving something dynamically, but the use of a shell
script do automate the process could negate that, and I think it's a
better solution.
